Article
Stereo rectification and stereo matching are two critical components for the practical application of stereo vision systems. Previous studies treat them as two individual issues. For stereo rectification, various traditional algorithms are proposed to estimate homography transformations, but the performance and the efficiency are unsatisfactory for...
Article
Efficient real-time disparity estimation is critical for the application of stereo vision systems in various areas. Recently, stereo network based on coarse-to-fine method has largely relieved the memory constraints and speed limitations of large-scale network models. Nevertheless, all of the previous coarse-to-fine designs employ constant offsets...

Article
Semi-global matching (SGM) is favored for high accuracy real-time stereo matching design as it achieves a good trade-off between disparity image quality and computational complexity. Nevertheless, most of previous SGM designs so far are restricted to the real-time processing of small image resolution and disparity range, or achieve high throughput...

Video display processing is an indispensable module in a variety of multimedia systems. With the increase of video format to 4Kx2K@60fps, the design of efficient display processing circuit faces severe challenges. This paper presents a video display processor which supports a variety of video formats and integrates multiple advanced algorithms for...
Preprint
Deep neural networks allow for fusion of high-level features from multiple modalities and have become a promising end-to-end solution for multi-modal sensor fusion. While the recently proposed gating architectures improve the conventional fusion mechanisms employed in CNNs, these models are not always resilient particularly under the presence of se...
Article
Large disparity stereo matching is critical to the application of a stereo vision system especially for outdoor scenes. Nevertheless, how to efficiently design high accuracy large-disparity stereo matching on a field-programmable gate array (FPGA) is still a grand challenge. The computational complexity of previously proposed stereo matching is ine...
Article
Guided image filtering (GIF) is a promising edgepreserving filtering technique that has been applied in a variety of applications. Nevertheless, an efficient VLSI architecture design of GIF is still very challenging for the real-time processing of full-HD videos. Previously proposed architectures are somewhat inefficient in terms of either on-chip...
Conference Paper
Although coding artifacts reduction is one of indispensable modules in video display processing system, its VLSI design is still rarely studied. Existing coding artifacts reduction approaches mainly focus on in-loop techniques, the other post-processing methods have not addressed the challenges posed by display system and are actually inapplicable...
Article
High-quality and cost-efficient image upscaling design is very important for many real-time video processing applications, especially when the display panel resolution reaches ultrahigh definition. Compared with New Edge-Directed Interpolation (NEDI) based implicit edge directional upscaling, explicit methods require less computational resource and...
