Adaptive motion-compensated interpolation for frame rate up-conversion

In this paper, we propose a frame rate up-conversion (FRC) algorithm using adaptive motion compensation (MC) that reduces the blocking artifacts due to block-based processing. The proposed method uses the motion analysis to determine the type of motion and applies the motion-compensated interpolation (MCI) adaptively. Experimental results indicate good performance of the proposed MCI scheme with significantly reduced blocking artifacts.

Development of an experimental full-digital HDTV system: algorithm and implementation

This paper describes the algorithm and implementation of an experimental full-digital HDTV system we have recently developed. The video compression algorithm is based on motion-compensated DCT without B (bidirectional prediction) frames and the audio compression is based on subband analysis/synthesis technique. The algorithms have commonalties with international standards such as MPEG, with some additional features. The system has been implemented using off-the-shelf ICs and programmable logic devices, and provides a fairly good video/audio quality (28-38 dB peak-to-peak signal-to-noise ratio for video) despite relatively low complexity. >
