This work presents a rigorous and objective evaluation of two progressive image transmission techniques in a frame work of telemicroscopy of biological specimens. First of all, a Lossless Progressive Image Codec (LPIC) which is based on a specific wavelet transform and an efficient en coding method is introduced. This system is then com pared to the standard Progressive-JPEG (P-JPEG) for the specific task of detecting biological specimens in the im ages progressively received by a biologist controlling a re mote transmission electron microscope (TEM). Both meth ods have been quantitatively compared by means of a task oriented methodology that guarantees an objective compar ison. The results that have been obtained allow to claim with statistical significance that our method outperforms the standard P-JPEG throughout the transmission process.
