To monitor the large area covered by water desirably, underwater acoustic networks have grown rapidly in the recent decade. However, due to the differences between terrestrial radio propagation and underwater acoustic propagation, it is crucial to design energy efficient routing protocols for underwater acoustic network. In this paper, we propose a power efficient clustered routing protocol named...
Superpixel segmentation is popularly used as a preprocessing in image segmentation and object recognition. However, none of effective superpixel segmentation algorithms have been proposed to highlight the contour features of the salient object in image, and they are difficult to describe the irregular superpixel boundaries. That will make a bad impact on subsequent image processing. In this paper,...
Due to the influence of both background interference and time-varying position, it is difficult to detect the moving object by computer vision in the complex background environment. This paper novelly builds a topological structure of typical features to detect object. The presented method can effectively detect the object which is scaling, rotating or in affine transformation, because of the using...
In intra string copy (ISC) technique for screen content coding, since the two string matching parameters, string position offset (pos) and string length (len), exhibit some unusual characteristic, directly applying the existing HEVC binarization to the one-dimentional (1-D) string matching parameters results in poor entropy coding performance. To solve this problem, in this paper, we propose a bijective...
In this paper, we present an arbitrary shape matching (ASM) coding technique for screen contents. In ASM coder, a Coding Unit (CU) is broken into multiple pixel sample strings. Each string called matched string in the CU has a matching string in the previously coded and reconstructed pixel buffer. Then the distance (either 1D or 2D) between the matching string and matched string and the length of...
Computer screens contain both discontinuous-tone content and continuous-tone content, which have essentially different characteristics. Thus, dual-coder approach is needed to effectively compress screen contents. This paper proposes a Pseudo-2D-matching (P2M) coder based dual-coder architecture for screen contents. An input Largest Coding Unit (LCU) is pre-coded simultaneously by a P2M coder and a...
