High noise level from darkness and low dynamic range are two characteristics of low light surveillance image that severely degrade the visual quality. Traditional low light image enhancement methods merely use the 2D cues without the depth information of the scene. Recently, the depth based image enhancement methods are proposed to enhance the depth perception of the image. However, these depth based...
We describe an algorithm for dynamic texture synthesis of video sequences of frames exhibiting certain stationary properties over time, such as sea-waves, whirlwind or moving crowds. The algorithm is based on taking into account the similarity among reference images in the video inter-frame coding. It allowed us to better express the time-varying relationship of the dynamic texture and to extend the...
In this paper we focus on building low latency resource location service over unstructured Peer-to-Peer (P2P) networks. In state-of-the-art search approaches in unstructured P2P systems ,they often evaluate efficiency by overlay hops, while two nodes logically adjacent maybe physically far away and from user's QoS, clients always want to acquire as many as objects in a short time, so we propose an...
In video coding system, because of the delay between current picture and the reference pictures, the temporal prediction is not good for the video sequences with nonlinear motion and global illumination change between frames. Dynamic textures are sequences of frames of moving scenes that exhibit certain stationary properties in time, which have great significance in applications such as video production...
The traditional frame error concealment methods primarily predict the motion trend for the corrupted pixel or block, which would generate edge fragmentation and object deformation. When the damaged images contain the contents of the non-linear motion and the global illumination change, these methods would have bad effects. In order to improve the efficiency of frame error concealment, we propose an...
