Automatic Number Plate Recognition System for Vehicle Identification using Optical Character Recognition

Automatic Number Plate Recognition System for Vehicle Identification using Optical Character Recognition

Abstract: Automatic License Plate Recognition (ANPR) is an image processing technology that uses a license plate to identify the vehicle. The goal is to design an efficient automated vehicle identification system using the vehicle license plate. The system is implemented at the entrance of the security control of a highly restricted area, such as the military zones or the area around the main government offices, for example. Parliament, Supreme Court, etc. The developed system spots the vehicle and then captures the vehicle image. The region of the vehicle's plate is extracted using the segmentation of the image into an image. The optical character recognition technique is used for character recognition. The resulting data is used to compare it with records in a database for specific information such as the owner of the vehicle, place of registration, address, etc. in real image. It is observed in the experiment that the developed system successfully detects and recognizes the vehicle's plate in real images.

Automatic Number Plate Recognition System for Vehicle Identification using Optical Character Recognition

Number plate acknowledgment is a type of programmed vehicle recognizable proof. [2] A number plate is the one of a kind recognizable proof of vehicle. [3] It is a picture preparing innovation used to distinguish vehicles by their own particular number plates. Constant number plate acknowledgment assumes an essential part in keeping up law requirement and keeping up movement rules.[5] It has wide applications ranges, for example, toll court, stopping region, exceedingly security territories, visitor's regions and so forth. Number plate acknowledgment is intended to distinguish the number plate and afterward perceive the vehicle number plate from a moving vehicle consequently. Programmed number plate acknowledgment has three noteworthy parts: vehicle number plate extraction, character division and Optical Character Recognition (OCR).[6]Number plate extraction is that phase where vehicle number plate is recognized. The recognized number plate is pre-prepared to evacuate the clamor and after that the outcome is passed to the division part to portion the exclusively characters from the removed number plate. The

The link budgets allow receiving transmitted AIS signals from space, and consequently a global maritime surveillance can be considered. However, some challenges arise, especially message collisions due to the use of a Self Organized Time Division Multiple Access (SOTDMA) protocol (not designed for satellite detecting). Thus, advanced signal processing for separation of received signals is needed.

Design of Lignin Sensor for Identification of Paper Grades for an Automatic Waste Paper SortingSystem.

Design of Lignin Sensor for Identification of Paper Grades for an Automatic Waste Paper SortingSystem.

Besides being a proof-of-concept sensor for paper grade identification, this sensor’s inherent flexibility allows the same set-up to be used both for experimentation purposes and as an industrial standard sensor when the monochromator is removed. A series of experiments were conducted to study the effects of various chemicals in the paper and other factors that might influence the fluorescence due to lignin from the samples. Fluorescence intensity is a relative measurement that depends on instrument characteristics. Instrument factors, such as light source fluctuations, optical misalignments, and drift in the detector electronics, also affect fluorescence intensity measurements. Intensity measurements are also affected by nonspecific background fluorescence. Photobleaching of the fluorophore is another potential source of error in intensity-based fluorescence. Additionally, the presence of optically absorbing compounds in the sample can introduce additional measurement artifacts. This makes comparison of data taken with different instruments, or even with the same instrument at different times, difficult. Fluorescence intensities can be standardized only in conditions close to ideal and hence this attempt is not to standardize the fluorescence intensity values for each grade, instead, it is to provide a sensor that would distinguish between grades. In distinguishing between grades, it can be conveniently assumed that all grades are subjected to the same external conditions and also the output from every sample is subjected to the same instrument factors. All fluorescence intensity graphs obtained from this research have therefore been normalized to the peak values since it is the trends in the graphs and the ability of the sensor to distinguish between grades that matter. The sensor could be made more accurate by using ratiometric measurements, however, ratiometric measurements require an increase in instrument complexity and it is also instrument-dependent.

DIVERSITY

THE THROUGHPUT FOR MULTI HOP RELAY WIRELESS SENSOR NETWORKS BASED ON COOPERATIVE DIVERSITY

Running red lights (RRL) currently become a hotspot social issue. Although it is commonly mentioned to detect and warn by using traffic monitoring, this idea has still remain in human recognition. Therefore, this paper designs a method to remedy it, which can detect the behavior of the pedestrians crossing the road automatically. From the sequential images taken by traffic monitoring, the use of optical flow estimating the track of motion objects whether cross the designated area enables automatic identification, then we carry out frames subtraction to isolate and identify the pedestrians from the moving objects. Combine the advantage of both algorithms, a system is presented to recognize the RRL event. Ultimately, the experiment confirms and indicates that what we proposed works effectively in some way.

Efficient Optical Character Recognition System for Automatic Soccer Player's Identification

Efficient Optical Character Recognition System for Automatic Soccer Player's Identification

We can notice that the use of the template matching technique is well suited for our system of automatic number recognition of soccer players. On one hand, template matching is particularly fast when used in context of our system, be- cause it requires only the recognition of numerical characters, rather than a wider range of alphanumerical characters as in other applications, such as license plate recognition (LPR). Indeed, our template stores in total only 10 images of one- digit numbers (0 to 9). Hence, the matching is performed against a maximum of ten stored images, in order to recognize the extracted character, which is compu- tationally very efficient. Moreover, the scale sensitivity of the template matching technique is used in our work as an advantage, since smaller dimensions of the template dimensions lead to a faster matching. On the other hand, the recogni- tion rate obtained by our implementation of this method in our system is much higher than those presented in the literature as discussed in Section 3.

Automatic Identification of Arabic Dialects

Automatic Identification of Arabic Dialects

In this work, automatic recognition of Arabic dialects is proposed. An acoustic survey of the proportion of vocalic intervals and the standard deviation of consonantal intervals in nine dialects (Tunisia, Morocco, Algeria, Egypt, Syria, Lebanon, Yemen, Golf’s Countries and Iraq) is performed using the platform Alize and Gaussian Mixture Models (GMM). The results show the complexity of the automatic identification of Arabic dialects since. No clear border can be found between the dialects, but a gradual transition between them. They can even vary slightly from one city to another. The existence of this gradual change is easy to understand: it corresponds to a human and social reality, to the contact, friendships forged and affinity in the environment more or less immediate of the individual. This document also raises questions about the classes or macro classes of Arabic dialects noticed from the confusion matrix and the design of the hierarchical tree obtained.

An Automated Vehicle License Plate Recognition

An Automated Vehicle License Plate Recognition

necessitates the use of automated systems to maintain vehicle information. The information is highly required for both management of traffic as well as reduction of crime. Number plate recognition is an effective way for automatic vehicle identification. Vehicle Number Plate Detection (VNPD) is a mass surveillance system that captures the image of vehicles and recognizes their license number. Vehicle Number Plate Detection (VNPD) system is a type of intelligent transportation system (ITS).Some of the existing algorithms based on the principle of learning takes a lot of time and expertise before delivering satisfactory results but even then lacks in accuracy. In the proposed system an efficient method for recognition for Indian vehicle number plates has been devised. The algorithm aims at addressing the problems of scaling and recognition of position of characters with a good accuracy. The objective is to design an efficient automatic authorized vehicle identification system by using the Indian vehicle number plate such that the number plate of vehicle can be identified accurately and to implement it for various applications such as automatic toll tax collection, parking system, Border crossings, Traffic control, stolen cars etc In this proposed system , different phases such as number plate localization, character segmentation & recognition of the number plates are carried out. The system is mainly applicable for non standard Indian number plates by recognizing single & double line number plates under different varying illumination condition and works on multilingual, multi colour number plates according to Indian condition.

Automatic Identification of Rhetorical Questions

Automatic Identification of Rhetorical Questions

After model selection via cross validation, our to- tal feature space dimensionality varies between 2914 for the precedent only feature set and 16615 for the question + subsequent feature set. Distinct n-gram and POS n-gram features are considered for each of same speaker and different speaker for precedents and subsequents so as to capture the distinction between the two. Examining the rel- ative number of features selected for these sub- feature sets also gives a rough idea of the strength of the various cues. For instance, same speaker feature dimensionality tended to be much lower than different speaker feature dimensionality, sug- gesting that considering context uttered by the re- spondent is a better cue as to whether the question is rhetorical. Additionally, unigrams and bigrams tend to be more useful features than POS n-grams for the task of rhetorical question identification, or at least considering the less common POS n-grams is not as predictive.

Identifying Moving Objects Using Background Subtraction, Optical Flow Method, Deep Neural Network for Camera in Motion Using PYNQ Architecture: Review of Recent Research Trends

Identifying Moving Objects Using Background Subtraction, Optical Flow Method, Deep Neural Network for Camera in Motion Using PYNQ Architecture: Review of Recent Research Trends

Over the ongoing years, Moving object detection is an imperative and vital part in the field of computer vision because of its extensive variety of utilizations like video observation, checking of security at air terminal, law requirement, video compression, programmed target identification, marine surveillance and human action recognition. Surveillance frameworks have increased incredible significance because of expanding security demands. Investigating the whole place is a critical and troublesome undertaking. In this manner surveillance systems are generally utilized in numerous regions. Generally, moving item is identified by two kinds of Camera: Static camera and Moving camera. Static camera recognizes the object by the Background subtraction Algorithm and screens the similar area. However, the supposition of the stationary camera has limits of the use of detection algorithm on account of increment of moving camera stages, for example, vehicles, robots and cell phones. Moving camera can screen bigger regions in its moving way. The video frames of a stationary camera will have a similar background, however it can't be the equivalent for moving camera frame since every one of the purposes of the video frames will change their position on each move. A video is a gathering of fundamental structural units, for example, scene, shot and frame related with sound information.

2.2 Acquiring the Automatic Thesaurus There are many alternative distributional similarity measures proposed in the literature, for this work we used the measure and thesaurus construction method described by Lin (1998). For input we used grammatical relation data extracted using an automatic parser (Briscoe and Carroll, 2002). For each noun we considered the co-occurring verbs in the direct object and subject relation, the modifying nouns in noun-noun relations and the modifying ad- jectives in adjective-noun relations. We could easily extend the set of relations in the future. A noun, ,
