- W2043959417 abstract "Image compression algorithms based on full-frame discrete transforms completely eliminate the artifacts generated by block quantization techniques. Previously, we have shown that full-frame compression using an adaptive two-dimensional bit-allocation table is capable of achieving compression ratios as high as 10:1 to 20:1, while maintaining excellent image fidelity, when applied to computed radiography images, and film radiographs digitized with 2K x 2K resolution. Cross-sectional images such as computed tomography and magnetic resonance have spectral properties qualitatively different from those of projection radiographs. We report results of a study on the efficiency of our algorithm applied to images from these digital modalities. We find that we can achieve excellent results with compression ratios in the range 3:1 to 7:1. For CT images of the head, previous attempts at using the full-frame technique had required a hybrid method that used separation of skull and soft tissue. This is unnecessary with our new two-dimensional bit-allocation table. The study was performed on a hardware implementation of our algorithm which can compress a 512 x 512 x 12-bit image in less than 1.5 seconds." @default.
