In this paper , a new method for image compression based on adaptive quantization using set of selected bit planes is being proposed .This technique combines adaptive quantization with an additional unit, with the aim of checking the intensity variation of each image block, and selects bit planes on basis of their intensity variations as compared to predefined threshold. Block truncation method and adaptive quantization coding method for image compression are also explained. The results obtained showed a good reduction in bpp compared with the AQC algorithm, with a little loss in PSNR due to the dropping of some blocks that claimed to be low intensity variation according to a comparison with predefined thresholds for each color plane.
