The F-transform preprocessing for JPEG strong compression of high-resolution images
Original language description
We are focused on improving the JPEG compression algorithm in the cases where a high ratio compression is required. For this purpose, we propose a preprocessing based on the F-transform. We develop a new discrete version of the inverse F-transform and newhybrid image compression and decompression algorithms, which combine JPEG with the F-transform. In the compression phase, JPEG follows the direct F-transform, while in the decompression phase, the methods are performed in the opposite order, and the new inverse F-transform is applied.We justify and illustrate on high-resolution benchmarks three main advantages of the proposed combination over the pure JPEG.Finally, we propose an easy way to use the hybrid FzT +JPEG compression and decompression algorithms in the current JPEG standard.
