This study aims to achieve video compression by using a novel lifting - based hybrid encoder which also uses motion compensation. The proposed encoder separates video frames into temporal groups within which certain frames are selected for producing temporal and spatial predictions over the rest of the frames. The predictions utilize spatio-temporal lifting together with motion compensation. The combination of spatial information with temporal changes is inspired from the edge-adaptive lifting idea, which alters prediction directions in images. A further incorporation of well-known block-matching methods with different levels was observed to improve the performance. To provide the first compression results, unpredicted frames and residues between the predicted frames and their originals are quantized and entropy encoded. PSNR measurements are used to measure the performance analysis of the proposed encoding method.

Experimental results reveal that higher compression ratios are obtained as block-matching level is increased, while Peak signal to noise ratio (PSNR) values remain in reasonable ranges. PSNR values of around 29 dB are obtained with a 1000:27 compression ratio.
