Human action recognition of depth sensors has drawn wide attentions in computer vision and multimedia processing areas. In contrast to simple periodic actions, irrelevant actions or sharing sub-actions between different classes of two-person non-periodic interactions make this task challenging. This paper presents heterogeneous features fusion with Collaborative Representation (CR) to address this...
Information fusion is a key research area widely applied to various multimedia analysis tasks such as artificial intelligence, humancomputer interaction, robotics, distributed computing, financial systems and security/surveillance. Feature level fusion has been considered as the most promising fusion method due to the rich information presented at this level. A critical operation of feature level...
Although recognition of vehicle license plate is well studied, characters can be obscured by color stains due to rust, mud, peeling paint or fading colors and become unrecognizable. In this paper, two approaches are presented to remove stains from license plate images by using photometric stereo technique and hole filling algorithm of texture synthesis respectively. The former method extracts height...
