Abstract: Reducing image file size by means of lossy compression algorithm scan lead to distortions in image content affecting detection of fine detail structures, either by human or automated observation. In the case of microscopic images of blood cells, which usually occupy large amounts of disk space, the use of such procedures is justified within a controlled quality loss. Although JPEG 2000 remains as the accepted standard for lossy compression, still a set of guidelines need to be established in order to use this codec in its lossy mode and for particular applications. The present paper deals with a quality analysis of reconstructed microscopic leukocytes images after they have been lossy compressed. The quality loss is investigated near the lower compression bound by evaluating the performance of several segmentation algorithms together with objective quality metrics. The value of compression rate of 142:1 is estimated from the experiments.
