Abstract 

This paper proposes a low-complexity intra-frame video coding system for very low resolution sequences. The application focuses on power constrained wireless visual sensors, recording extremely low-resolution video, namely, 30x30 pixels. In the proposed framework, high-performance video coding techniques such as block-based transforms, intra prediction and entropy coding are employed. The proposed system features several different configurations, all of which are evaluated both in terms of coding efficiency and computational complexity. Based on the experimental results, the best configuration is identified. Experimental results show that the proposed configuration achieves better coding performance than the H.264/AVC Intra frame codec, at only 23.7% of its encoding complexity.
