H.264/AVC intra-frame encoding contains several computation-intensive coding tools that form a long data dependency loop that is difficult to speed up. In this paper, we present a low-power and high-performance H.264/AVC intra-frame encoder. We propose several novel approaches to alleviate the performance bottleneck caused by the long data dependency loop among 4 × 4 luma blocks, integrate an efficient...
Estimating 3D motion parameters from a sequence of images is of crucial importance in many image analysis applications, ranging from robot vehicle guidance to obstacle avoidance, target tracking, the reconstruction of 3D models. In this paper, a novel algorithm to recover parameters for translational motion using such a parallel binocular system is presented. This approach overcomes the difficulty...
We present a high-performance hardware architecture for H.264/AVC full-mode intra-frame encoding. We propose a novel method to alleviate performance bottleneck caused by the long data dependency loop among 4times4 blocks. Synthesized into a TSMC 0.13 mum CMOS cell library, our design takes 212 K gates to run at 138 MHz and is able to real-time encode 1080HD (1920times1088) video sequences at 30 frames...
We propose a high performance architecture for fractional motion estimation and Lagrange mode decision in H.264/AVC. Instead of time-consuming fractional-pixel interpolation and secondary search, our fractional motion estimator employees a mathematical model to estimate SADs at quarter-pixel position. Both computation time and memory access requirements are greatly reduced without significant quality...
