Data compression thesis

The main purpose of this technique is to extract more information from noisy images and surveillance imagery. Data is compressible because of inherent redundancies in the data, mathematically expressed as correlation structures.

A probabilistic graphical model based data compression architecture for Gaussian sources

Chapter 3 investigates the use of adaptivity in data compression algorithms. This area has a tremendous scope for research. This process is entirely different from the process of image enhancement in the sense that image enhancement improves the features of the image. The surveillance imagery is used in banks, ATMs, hospitals, universities, shopping malls, traffic signals.

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.

Following are the main methods of image restoration process: Image Acquisition Image Acquisition is a process of retrieving an image from source usually a hardware source. Converting the original image into feature and non-feature elements.

Department of Electrical Engineering and Computer Science.

It improves the quality of digital images to a certain level using various computer-based methods. Approx 24cmx17cmx3cm or approx 9. This work offers the most complete bibliography on this subject I am aware of. In FIP, the pixel values are changed to enhance the image quality.

The local extreme points are detected as the skeletal points. Massachusetts Institute of Technology. This work builds on recent research on model-code separation compression architectures to extend this concept into the domain of lossy compression of continuous sources, in particular, Gaussian sources.


A thesis submitted to the Graduate Council of Texas State University in partial fulfillment of the requirements for the degree of Master. 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. 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.

Data Compression Using a Multi-residue System (Mrs)

data compression for radar signals: an svd based approach by zhen zhou b.s.e.e., tsinghua university, thesis submitted in partial fulfillment of the.

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.

Latest Thesis Topics in Digital Image Processing

In the rest of the text, any mention of compression should be understood as adaptive lossless data compression. Image Compression By Wavelet Transform by Panrong Xiao Digital images are widely used in computer applications.

Uncompressed digital images require considerable storagecapacity and transmission bandwidth. Efficient image compression solutions are becoming more critical with the recent growth of data intensive, multimedia-based web .
