Abstract :
This paper presents a new approach for lossless and lossy compression of DNA microarray images. A DNA microarray is a single stranded DNA fragments, arranged on a glass or nylon slide where the hybridized spots can be detected and extracted by laser scanning of the microarray. The spatial optimization techniques and transforms are employed to achieve excellent compression ratio.
