A RIGOROUS EVALUATION OF PROGRESSIVE IMAGE TRANSMISSION METHODS FOR TELEMICROSCOPY OF BIOLOGICAL SPECIMENS

摘要

This work presents a rigorous and objective evaluation of two progressive image transmission techniques in a framework 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 encoding method is introduced. This system is then compared to the standard Progressive-JPEG (P-JPEG) for the specific task of detecting biological specimens in the images progressively received by a biologist controlling a remote transmission electron microscope (TEM). Both methods have been quantitatively compared by means of a task-oriented methodology that guarantees an objective comparison. The results that have been obtained allow to claim with statistical significance that our method outperforms the standard P-JPEG throughout the transmission process.
