In the recent years,microarray technology gained attention for concurrent monitoring of numerous microarray *** remains a major challenge to process,store and transmit such huge volumes of microarray ***,image compression techniques are used in the reduction of number of bits so that it can be stored and the images can be shared *** techniques have been proposed in the past with applications in different *** current research paper presents a novel image compression technique i.e.,optimized Linde–Buzo–Gray(OLBG)with Lempel Ziv Markov Algorithm(LZMA)coding technique called OLBG-LZMA for compressing microarray images without any loss of *** model is generally used in designing a local optimal codebook for image *** construction is treated as an optimizationissue and can be resolved with the help of Grey Wolf Optimization(GWO)*** the codebook is constructed by LBGGWO algorithm,LZMA is employed for the compression of index table and raise its compression efficiency *** were performed on high resolution Tissue Microarray(TMA)image dataset of 50 prostate tissue samples collected from prostate cancer *** compression performance of the proposed coding esd compared with recently proposed *** simulation results infer that OLBG-LZMA coding achieved a significant compression performance compared to other techniques.
