Optimal filter design for low entropy pyramid coding
نویسندگان
چکیده
In a previous published work, the lowest entropy for lossless encoding of the standard image " Lena " is found to be 5.311 bpp [3]. In this paper, we design an optimal filter using the Hybrid method approach that will give lower entropy of 4.198 bpp for the same image with saving of 21.22% and with saving in computation complexity and encoded sample of 32% and 20%, respectively than that in [3].

A progressively predictive image pyramid for efficient lossless coding
A low entropy pyramidal image data structure suited for lossless coding and progressive transmission is proposed in this work. The new coder, called the progressively predictive pyramid (PPP) is based on the well-known Laplacian pyramid. By introducing inter-resolution predictors into the original Laplacian pyramid, we show that the entropy level in the original pyramid can be reduced significa...
متن کاملBurt and Adelson : Laplacian Pyramid the Gaussian Pyramid
We describe a technique for image encoding in which local operators of many scales but identical shape serve as the basis functions. The representation differs from established techniques in that the code elements are localized in spatial frequency as well as in space. Pixel-to-pixel correlations are first removed by subtracting a lowpass filtered copy of the image :From the image itself. The r...
متن کاملLossless Subband Image Compression Using Integer Coeecient Filter Banks
A new class of two-channel lter banks having integer lter coeecients is proposed. The integer lter coeecients are obtained by maximizing for subband coding gain. The number of bits required to represent the subband samples are kept low through eecient nonlinear implementation techniques. Several integer coeecient lter banks are tested for lossless image compression. An octave-band (dyadic) freq...
متن کاملLow entropy image pyramids for efficient lossless coding
An efficient image source coding technique gives good compression performance at low computational complexity. This research introduces an efficient coding technique, based on pyramid coding, that involves transforming an image into an equivalent lower entropy form prior to lossless coding. The proposed method is also a multiresolution technique that facilitates progressive image transmission.
