Abstract:

In this work, lossless grayscale image compression methods are compared on a medical image database. The database contains ten different types of images with bit rates varying from 8 to 16 bits per pixel. The total number of test images was ca. 3000 originating from 125 different patient studies. Methods used for compressing the images include seven methods designed for grayscale images and 18 ordinary general-purpose compression programs. Furthermore, four compressed image file formats were used. The results show that the compression ratios strongly depend on the type of the image. The best methods turned out to be TMW, CALIC and JPEG-LS. The analysis step in TMW is very time consuming. CALIC gives high compression ratios in a reasonable time, whereas JPEG-LS is nearly as effective and very fast.
