چکیده

Video quality assessment is widely used for signal measure. Classic method is often use algebra method for make a compute model, such as PSNR, which often lead to difficult for alignment of video sequence number and it limit its application in real world. This paper presents a novel method bases on high dimensional space. The method considers a image as a point in high dimensional space and make correspond calculation. Firstly, it use special kernels to covering some image points from original image; then when a noised image is put into space, the method is performed to find the most similar one in highdimensional space and gives its similarity. Experimental results show that the propose method make the measurement easily and meet the real noised image sequence. The proposed method is constructive and this work can provide a very useful method for video quality assessment model.

Key-Frame Based Robust Video Hashing Using Isometric Feature Mapping

In order to identify videos on the Internet, a robust video hashing based on key frames and Isometric Feature Mapping (ISOMAP) is proposed in this paper. In this method, key frames extraction and hash generation are two major components. During the video hashing, key frame extraction is achieved by a uniform distribution vector and video tomography analysis, while hash generation is accomplishe...

Parallel Transport Frame in 4 -dimensional Euclidean Space

In this work, we give parallel transport frame of a curve and we introduce the relations between the frame and Frenet frame of the curve in 4-dimensional Euclidean space. The relation which is well known in Euclidean 3-space is generalized for the …rst time in 4-dimensional Euclidean space. Then we obtain the condition for spherical curves using the parallel transport frame of them. The conditi...

Adaptive Spectral Separation Two Layer Coding with Error Concealment for Cell Loss Resilience

This paper addresses the issue of cell loss and its consequent effect on video quality in a packet video system, and examines possible compensative measures. In the system's enconder, adaptive spectral separation is used to develop a two-layer coding scheme comprising a high priority layer to carry essential video data and a low priority layer with data to enhance the video image. A two-step er...

Action Change Detection in Video Based on HOG

Background and Objectives: Action recognition, as the processes of labeling an unknown action of a query video, is a challenging problem, due to the event complexity, variations in imaging conditions, and intra- and inter-individual action-variability. A number of solutions proposed to solve action recognition problem. Many of these frameworks suppose that each video sequence includes only one ...
