Small group people behavior analysis based on temporal recursive trajectory identification

Small group people behavior analysis has attracted much attention in recent years. How to detect, track and analyze the group behavior of related people is a challenging problem. In this paper, a framework for small group people behavior analysis is …

No-reference video quality assessment on mobile devices

The explosive growth of video applications and services on mobile devices has made it important to assess video quality. In this paper, we propose a no-reference video quality assessment method for mobile videos. Based on the analysis on common …

A Mesh-Based Method for Wavelet Video Coding Using Edge-Detection in Low Frequency Subband

In this paper, we propose a mesh-based method for motion estimation and compensation over low frequency subband for wavelet video coding. We concentrate on edge-detection information and apply different parameters using edge magnitude and edge angle …

Image interpolation based on decomposition

This paper proposes a new approach for interpolating natural images. Unlike other conventional interpolation methods, we exploit the characteristics of an image and decompose it into a texture part and a non-texture (cartoon) part. In the non-texture …

A Hierarchical Diffusion Algorithm for Community Detection in Social Networks

Community discovery is one of the most important steps to understand the social networks. We propose a hierarchical diffusion method to detect the community structure. Our algorithm is based on the idea that people in different communities usually …
