The Multiresolution Image Format

The Multiresolution Image Format

There are many raster based file formats nowadays, but at least in one point all of them are very similar to each other: the image contained by the file, has only one resolution on the entire image. This means that number of pixels of the image unambiguously can be computed knowing dimensions of this image (columns and rows). When the hardware used for displaying this image also known, the actual resolution can be defined as DPI.

High Efficiency Image File Format implementation

High Efficiency Image File Format implementation

14 3. HIGH EFFICIENCY IMAGE FILE FORMAT STANDARD The High Efficiency Image File Format (HEIF) is a new image file format standard for storing raster images, image sequences and related metadata. The standardiza- tion effort started soon after the High Efficiency Video Coding (HEVC) standard was finalized, when it was realized that HEVC had good compression performance also with still pictures, and could be used e.g. with digital cameras if it was pos- sible to save photographic metadata to the same file [10]. However, HEIF is not restricted to storing HEVC encoded images only, but it can contain other encoded bitstream formats as well. As HEIF is built on existing ISO Base Media File Format (ISOBMFF) and HEVC standards, these are presented briefly before proceeding to HEIF structure and features in more detail.

SECURE FILE AND IMAGE PROCESSOR

SECURE FILE AND IMAGE PROCESSOR

One primary detriment of utilizing blacklisting of document extensions is that it is relatively difficult to order a rundown that incorporates all the conceivable augmentations that an aggressor can utilize. For instance if the code is running in the facilitated condition, generally such situations permit countless Scripting languages, for example, pearl python Ruby and so on and rundown can be interminable. A vindictive client can without much of a stretch sidestep such check by uploading called "access", which contains the line of code like beneath as The extension is correct and you checked the document is really a Legitimate JPEG file according to its header. However, it could at present be a noxious JPEG utilizing one of the numerous image parser bugs to exploit customer downloading the file. There was no extraordinary protection against. Change over the JPEG to a GIF and back to JPEG, while changing overtake the image documenting content only and start Add Type application/x-httpd-php.jpg. The above line of code instructs apache webserver to execute jpg pictures as though they were PHP contents. The aggressor would now be able to upload a file with a jpg expansion, which contains the PHP code.

Automating Mobile Device File Format Analysis

Automating Mobile Device File Format Analysis

In order to allow for code reuse and provide more flexible options for developers to execute common programming tasks, a corpus of common functions are gathered together and made available to programmers to call; these are commonly referred to as libraries. Android applications bind to libraries either statically or dynamically. During static binding, all library function references are resolved before program execution and the library file links to the binary executable before program execu- tion. The consequence is a larger binary file but also allows for increased application portability – the program executes regardless of if the host operating system has the required libraries. If not statically bound, Android applications can dynamically link to a shared object library at execution. The decision occurs during the application build phase, where the linker neglects the dynamic library’s symbols and does not perform checks of the sections (.bss, .text, or .data); instead it checks if the dynamic library contains the symbols needed by the binary. If it finds them, then the linker creates the executable. This is illustrated in Figure 9.

A Framework for File Format Fuzzing with Genetic Algorithms

A Framework for File Format Fuzzing with Genetic Algorithms

Chapter 4 Mamba Fuzzing Framework Binary reconnaissance, as described in Chapter 3, is the first step in fuzzing applications with a genetic algorithm. The next step is to leverage data collected during reverse engineering, correlate it with dynamic analysis, and have a genetic algorithm measure performance based on the correlation. To facilitate measuring a negative test case’s performance based on static and dynamic analysis, a fuzzing framework must first fulfill most of the requirements derived in Chapter 2, and additionally support processing information exported during binary analysis along with tracing program execution. An analysis of preexisting fuzzing frameworks determined that the best option for fulfilling these requirements is to develop a new framework. This new framework, Mamba, concentrates on testing the robustness of a Mac OS X application’s file parsing routines. It implements general feedback fuzzer functionality and includes multiple feedback fuzzing algorithms. Mamba is an object oriented framework designed to create a rich environment for application testing. It is written in the Ruby scripting language which promotes rapid development and eventual cross platform support. Yukihiro Matsumoto developed Ruby around 1995 and adoption of the language has significantly increased since its introduction. Ruby is an interpreted language, and its interpreter and core are written in C. All major operating systems, Mac OS X, Windows, and Linux, support this language, and several alternative implementations of the original standard have been developed and adopted. By implementing a framework in a scripting language like Ruby, many low-level implementation errors are nullified and implementation time is decreased. For instance, Ruby mollifies most memory management problems, because it handles freeing memory with its own garbage collection algorithm.

Kepler Data Validation Time Series File: Description of File Format and Content

Kepler Data Validation Time Series File: Description of File Format and Content

The Kepler space mission searches its time series data for periodic, transit-like signatures. The ephemerides of these events, called Threshold Crossing Events (TCEs), are reported in the TCE tables at the NASA Exoplanet Archive (NExScI) 1 . Those TCEs are then further evaluated to create planet candidates and populate the Kepler Objects of Interest (KOI) table, also hosted at the Exoplanet Archive. The search, evaluation and export of TCEs is performed by two pipeline modules, TPS (Transit Planet Search) and DV (Data Validation). TPS searches for the strongest, believable signal and then sends that information to DV to fit a transit model, compute various statistics, and remove the transit events so that the light curve can be searched for other TCEs. More on how this search is done and on the creation of the TCE table can be found in Tenenbaum et al. (2012), Seader et al. (2015), Jenkins (2002). For each star with at least one TCE, the pipeline exports a file that contains the light curves used by TPS and DV to find and evaluate the TCE(s). This document describes the content of these DV time series files, and this introduction provides a bit of context for how the data in these files are used by the pipeline.

Context Parsing (Not Only) of the Object-File-Format Description Language

Context Parsing (Not Only) of the Object-File-Format Description Language

The Microsoft’s Windows Portable Executable (WinPE) [29] format also supports all the three file types — object files, executables, and libraries. Win- dows PE can be used on all Windows-based systems on architectures Intel IA-32, IA-64, x86-64, ARM, and others. The structure of the PE format is based on the COFF format [10]. It consists of a number of headers and sections that tell the loader how to map the file into memory. Each section has its own header and often a specific purpose, for illustration see 1. For example, the .text sec- tion holds the program code; .data sections hold global variables, .edata and .idata sections contain exported and imported symbols, etc.

Computing Aggregate Queries in Raster Image Databases Using Pre-Aggregated Data

Computing Aggregate Queries in Raster Image Databases Using Pre-Aggregated Data

query execution. In raster image databases, aggregation is a very important statistical concept used to represent a set of items by a single value, or to classify them into groups while determining a value for each group. The most widely used aggregations are add, average, mini- mum and maximum. Notably, performing aggregate op- erations on large volumes of multidimensional raster data pose several challenges to existing raster database tech- nology. That is, while delivering small-sized results, large data portions have to be touched during query evaluation. In application domains such as Geographic Information Systems (GIS), the computation of many fundamental operations requires the usage of aggregate functions [3] but to the best of our knowledge, pre-aggregation support has been provided for one single operation, namely, scal- ing(zooming). In a different application domain, most On-Line Analytical Processing (OLAP) systems adopt a pre-aggregation approach for ensuring adequate response time during data analysis. Based on the observation that data structures and operations in both application do- mains share similarities, our approach for speeding up ag- gregate operations consists in taking existing knowledge of OLAP pre-aggregation as a basis for defining an intel- ligent pre-aggregation scheme in raster image databases. OLAP pre-aggregation addresses three main problems: View Selection, Query Rewriting and View Maintenance. Despite the high maturity of these technologies [4], it has never been attempted, to the best of our knowledge, to adapt them to the field of raster image databases. In this paper, we focus on the problem of answering a query in the presence of pre-aggregated data. We present a pre-aggregation framework along with a cost model to study the effect of using pre-aggregation in the computa- tion of aggregate queries in multidimensional raster image databases.
