In this paper, we examine the importance of this \"distortion memory\" via a specific class of memory-based models denoted Distortion Chains that are used for predicting the distortion of the reconstructed video signal in case of missing multiple packets at the receiver. We show that taking into account even the smallest amount of memory that is possible can yield substantial gains in terms of prediction accuracy and packet selection (packet dropping) performance. An additional and rather surprising result of our study is the fact that in certain situations dropping an additional video packet (which could otherwise be delivered) can actually improve the quality of the reconstructed video","PeriodicalId":191719,"journal":{"name":"2005 IEEE 7th Workshop on Multimedia Signal Processing","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130795062","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper presents solutions to this allocation problem for three optimization objectives: minimizing the MSE of the decoded video over all the streams, maximizing the PSNR over all the streams, and minimizing the maximum MSE (equivalent to maximizing the minimum PSNR). Each is shown to be a convex problem which can be solved quickly using standard techniques. This paper then investigates the question of which objective should be used. Subjective tests were conducted to determine how well allocations made according to the various objectives correspond to the preferences of human test subjects. Results indicate, surprisingly, that the minimum MSE objective corresponds best to subjective preferences","PeriodicalId":191719,"journal":{"name":"2005 IEEE 7th Workshop on Multimedia Signal Processing","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114465782","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The entropy measurement, which is commonly adopted as an important feature to describe the degree of disorder in thermodynamics, is used as an underlying feature for identifying key postures. First, we use cumulative entropy change as an indicator to select an appropriate set of key postures from a human behavior video sequence and then conduct a cross entropy check to remove redundant key postures. With the key postures detected and stored as human posture templates, the degree of similarity between a query posture and a database template is evaluated using a modified Hausdorff distance measure.

Based on the distance transform, the proposed local relative distances pattern (LRDP) records the distance pattern of a color plane. Thus, LRDP can be regarded as an integration of chromatic and spatial information. The spectral information for the boundary and texture portion of an image is extracted by the devised frequency histogram. These two descriptors are integrated to form a robust CBIR system.

Summarizing such contents is one of the solutions to diminish the cost in browsing and grasp the contents rapidly. Most of the video summarization methods ever proposed extract `conspicuous' shots from audio/visual point of view, and combine them together to create a summary. These methods imply an issue of disregarding contextual dependency between shots or scenes. We propose a method of summary generation based on `film grammar', which keeps the dependency between shots or scenes. Experimental results show this method provides a viewer better summaries to comprehend the context","PeriodicalId":191719,"journal":{"name":"2005 IEEE 7th Workshop on Multimedia Signal Processing","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132763514","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
