Inverse Diamond Search Algorithm for 3D Medical Image Sets Compression
نویسندگان
چکیده
The scheme of motion estimation is introduced to exploit the redundancy between continuous frames of 3D medical image sets in this paper. The proposed scheme is based on inter-frame motion estimation of inverse diamond search algorithm. The residual images are encoded by the Huffman encoder. The test images include five sets of the heart and two sets of the brain MRI images. The average compression ratio of the inverse diamond search algorithm is similar to the JPEG_LS and diamond search algorithm. The inverse diamond search leads to speed improvement around 5 % over diamond search for all the tested MRI sets.
