Sažetak
The aim of this paper is to compare the quality of digitized chest X-ray images with digitally captured chest X-ray images in children with lung tuberculosis (TB), compressed using popular JPEG and JPEG2000 compression algorithms, for further electronic correspondence. All images were compressed using JPEG and JPEG2000 compression algorithms with six compression degrees (3 bpp, 1.5 bpp, 1 bpp, 0.7 bpp, 0.5 bpp, 0.3 bpp). Picture quality was evaluated by means of usual objective measures of picture quality such as MSE, SNR and PSNR. All compressed images were shown to physicians, who were asked to evaluate diagnostic accuracy of each image (by poor, good or excellent). According to physician's subjective evaluation both JPEG and JPEG2000 compression for all X-ray digitized images (all TB-attributes) were accepted as excellent.
