Entropy Conserving Binarization Scheme for Video and Image Compression
Madhur Srivastava
The paper presents a binarization scheme that converts non-binary data into a set of binary strings. At present, there are many binarization algorithms, but they are optimal for on…
Quantum Image Representation Through Two-Dimensional Quantum States and Normalized Amplitude
Madhur Srivastava, Subhayan R. Moulick, Prasanta K. Panigrahi
We propose a novel method for image representation in quantum computers, which uses the two-dimensional (2-D) quantum states to locate each pixel in an image through row-location a…
An Adaptive Statistical Non-uniform Quantizer for Detail Wavelet Components in Lossy JPEG2000 Image Compression
Madhur Srivastava, Satish K. Singh, Prasanta K. Panigrahi
The paper presents a non-uniform quantization method for the Detail components in the JPEG2000 standard. Incorporating the fact that the coefficients lying towards the ends of the…
A Semi-automated Statistical Algorithm for Object Separation
Madhur Srivastava, Satish K. Singh, Prasanta K. Panigrahi
We explicate a semi-automated statistical algorithm for object identification and segregation in both gray scale and color images. The algorithm makes optimal use of the observatio…
Non-uniform Quantization of Detail Components in Wavelet Transformed Image for Lossy JPEG2000 Compression
Madhur Srivastava, Prasanta K. Panigrahi
The paper introduces the idea of non-uniform quantization in the detail components of wavelet transformed image. It argues that most of the coefficients of horizontal, vertical and…
Multisegmentation through wavelets: Comparing the efficacy of Daubechies vs Coiflets
Madhur Srivastava, Yashwant Yashu, Satish K. Singh +1
In this paper, we carry out a comparative study of the efficacy of wavelets belonging to Daubechies and Coiflet family in achieving image segmentation through a fast statistical al…
