This paper presents prefix codes which minimize various criteria constructed as a convex combination of maximum codeword length and average codeword length or maximum redundancy and average redundancy, including a convex combination of the average of an exponential function of the codeword length and the average redundancy. This framework encompasses as a special case several criteria previousl...

This paper introduces a fast algorithm for microarray image segmentation and an object-based coding technique to compress the segmented DNA microarray images using modified embedded block coding with optimized truncation (EBCOT) [1]. Microarray images are segmented into foreground and background by a modified Mann-Whitney test-based algorithm, which is much faster than Chen et al.’s original on...

We present an image compression scheme that is error resilient and offers lossless decompression in the absence of channel noise. Attempts are made to detect transmission errors and data found to be in error is discarded so as not to pollute the decompressed output. This is achieved while still maintaining a level of compression that is competitive with lossless image compression standards.
