I. INTRODUCTION
MapReduce [1] has materialized as the nearly all significant programming model for large-scale distributed data processing. The current years using Hadoop open source framework. Hadoop and its processing model are recently formed and like several other innovative technologies might have its own issues, such as need of acquaintance of the mainstream of IT society with it, lack of sufficient specialist forces, and unnecessary defects and problems appropriate to its novelty. though, this processing style that use MapReduce model and distributed file system, will be amongst the nearly all helpful tools for image processing and pattern recognition in the coming years appropriate to its faithfulness with cloud computing structures. To
proposed technique for image data classification using semi supervise learning algorithm based on (Support vector machine) SVM. An Image Recognition System is use to automatically categorize or substantiate a person or an object from a digital image One of the ways to do this is by compare chosen image features from the database. This use for retrieving the subsequent images from the database base on their feature of images which consequent the image itself. The retrieval of the image is base on the content of an image and it is additional resourceful than the text based which is called content based image retrieval that are used for a a variety of application like vision technique of computer .
conventionally, investigate of the images are with text, tags or keywords or annotation allocate to the image while store into the databases. Where as if the image which is accumulating in the database are not exclusively or specially tag or wrongly illustrate then it’s unsatisfactory, arduous and enormously time overwhelming job for searching the exacting image in the huge set of databases. For receiving most precise result Image Recognition Systems are used which search and retrieve the query images from the huge databases based on the image content which is resulting from image itself by with image processing techniques.
To store such immense amount of data as a substitute of with an effortless Client Server architecture it’ll be enhanced to use architecture where in the data demonstrate the property of logical independence. A scheme where in the data has to be distributed on a huge number of workstations so that it might reduce the load of analysis on a single machine.
lot around us at every times. each digital process system, mobile devices ,sensors and transmit it. Big data is inward from manifold sources at an disturbing velocity, quantity and diversity. To extract significant value from big data, you require optimal processing power, analytics capability and skills. To utilize semi supervise learning algorithm based on support vector machine. To classified the data label and unlabeled . receiving the accrue data set subsequent to training testing.
Spatial Big Data Spatial big data refers to data or in sequence that bring up and illustrate geographic features and restrictions of objects [4]. Spatial big data is accumulate into databases as organize and topology for satellite objects such as ocean, lake, plants etc. Spatial data [5] can be as well called as geospatial data, spatial information or geographic information. This type of data is usually process and manipulate by GIS. Spatial data can be categorize into three types: raster data, vector data and network data [6]. Section 2 explains related work in image processing with HDFS and MapReduce over Hadoop framework. Section 3 describe anticipated two phase extended system semi supervise SVM learning algorithm and usage of APIs. Section 4 describe experimental consequences, and Section 5 present the conclusions and future work.

IV.RESULT ANALYSIS
Our training and testing environment is collected of 5 PC computer(Intel i5, 16GB Memory, 2TB HDD, Ubuntu 16.0 64 bit Linux systems, Hadoop 2.6 and Java SE 7), the primary computer worked as NameNode whereas the responsibility of others is DataNode. every of them are associated by 1 gigabit switch. The remote sensing images use for the experiment are get from the satellite, They are consisted of 100 image files, every of which has 6366 5840 pixels declaration , 5 bands and its size is about to 60MB.In arrange to validate the efficiency of our scheme, every the image data more randomly alienated into 5 groups. Then we decide the classification tool in the OTB which describe in the subsequent phase of processing (a map algorithm) to be appropriate a categorization to one of the input image files (Fig.2) and to evaluate the consequences with a semi supervise learning algorithm to the identical input file. Illustrate a evaluation of the classification accuracy amongst the proposed approaches and the semi supervise learning algorithm Based on SVM. As we be able to note, the overall accuracy is amplified from 82.50% for the semi supervise learning algorithm Based on SVM to 90.94% for our technique, acquire complete benefit of the integrated configuration possessions, and it create enhanced consequences than the traditional semi supervise learning. So our proposed approach application will be valuable in future to the subsequent sectors: 1. Meteorological disaster -
Violent, unexpected and unhelpful modify to the environment connected to, formed by, or distressing the earth's atmosphere, particularly the weather-forming process. 2. Military navigation - learning of traverse during untried ground by base or in a land vehicle. 3. Key end corresponding among two images competition the key points next to a database of that get from training images by pronouncement the adjacent neighbor a key summit with minimum Euclidean distance. 4. Monitoring approximately the
sphere to extract discriminative information
concerning regions of the world for which GIS data is not obtainable. 5. Feature vector generation and its learning is extremely important characteristic in machine learning.
IV. CONCLUSIONS AND FUTURE
WORK
Image processing applications covenant with processing of pixels in comparable, for which Hadoop and MapReduce can be successfully used to get superior throughputs. though numerous of the algorithms in Image Processing and additional scientific computing, necessitate use of neighborhood data, for which the obtainable technique of data association and processing are not appropriate. We presented an extensive HDFS and MapReduce interface, called Semi-supervised SVM algorithm, for image processing application. Semi-supervised SVM algorithm present extended library of HDFS and MapReduce to development the single large scale images with high level of concept over writing and reading the images. We plan to implement the bi-directional opening as well in the proposed system, which would be the prerequisite for huge scale canvas images. In future effort propose MapReduce APIs could be comprehensive for a lot of more Image giving out and Computer vision modules. It is also proposed to enlarge the similar to multiple image formats in the inhabitant format itself.
