Data compression thesis

The surveillance imagery is used in banks, ATMs, hospitals, universities, shopping malls, traffic signals. Converting the original image into feature and non-feature elements. It is one of the trending topics in digital image processing for the thesis.

Applications Data compression thesis User Interfaces The degradation can be blur, noise which diminishes the quality of the image. For skeletal decomposition, a morphological approach is followed to decompose a complex shape into simple components.

Morphological thinning is used to eliminate pixels from the boundary. Data is compressible because of inherent redundancies in the data, mathematically expressed as correlation structures. This work, meant to be an exploration in a new direction in data compression, is at the intersection of Electrical Engineering and Computer Science, tying together the disciplines of information theory, digital communication, data compression, machine learning, and cryptography.

Massachusetts Institute of Technology Date Issued: Following are the three main processes of skeletonization: It improves the quality of digital images to a certain level using various computer-based methods.

Image Acquisition can also be done through line sensor and array sensor. This process is entirely different from the process of image enhancement in the sense that image enhancement improves the features of the image.

It provides an excellent and lucid review of the field, and should be equally as beneficial to newcomers as to those of us already in the field. Wavelet Thresholding Skeletonization Skeletonization is a process to reduce foreground details in a binary image to represent a general form of an object.

A probabilistic graphical model based data compression architecture for Gaussian sources

Hardback, pages, printed on acid free paper. Adaptive Data Compression Author: Image Acquisition Image Acquisition is a process of retrieving an image from source usually a hardware source. It finds its application in crime detection to analyze crime scenes through fingerprints and footmarks.

A data compression algorithm uses the knowledge of these structures to map the original data to a different encoding. Approx 24cmx17cmx3cm or approx 9. With the flexibility afforded by the modularity of the architecture, we show that the proposed system is free from many inadequacies of existing algorithms, at the same time achieving competitive compression rates.

Chapter 5 introduces a new class of adaptivity in data compression algorithms multimodal adaptivity and describes the MMDC algorithm which implements it.

Data Compression Using a Multi-residue System (Mrs)

Real-time image acquisition is also one of the forms of image acquisition. The image thus acquired is an unprocessed image.The GRIB file structure is designed for global distribution of meteorological data. World Meteorological Organization has built JPEG Compression into the new GRIB2 file format.

The implementation of JPEG compression in GRIB2. Apr 03,  · LZW Data compression on CUDA. I am doing mtech in computer science and part of my course a thesis work have to be done.I decided to analyse the performance of LZW data compression on GPU and CPU architecture.I installed GPU ocelot in ubuntu successfully and doing further body.

Definition A compression algorithm is adaptive if it dynamically adjusts to the data being processed. Definition A compression program (compressor, encoder, packer) is an implementation of a compression algorithm. In the rest of the text, any mention of compression should be understood as adaptive lossless data compression.

Lossless compression is a class of compression algorithms that allows the original data to be reconstructed perfectly from the compressed one while for lossy compression, it permits reconstruction only approximate to the original one and it is commonly allows for improved compression rates and smaller in file size.

The basic theorem is that an under-determined system of congruences could be solved to accomplish data compression for a signal satisfying continuity of its information content and bounded in peak-to -peak amplitude by the product of relatively prime moduli.

This thesis investigates this property and presents quantitative results along with.
