In video processing compression techniques are required to improve the efficiency of transmission and storage of video data. Data compression methods can be classified into two basically different categories: lossy compression methods and lossless compression methods. Lossless compression methods are required for medical image processing and for compressions broadcast materials. We developed a novel video lossless compression method using the Hilbert curve, by mapping the three-dimensional data to one-dimensional data along the curve and then applying adaptive linear prediction coding to the one-dimensional data. Experimental results show that better compression ratio is obtained with our method than with losslessJPEG, although the processing time for both methods is almost equal.
