In our CBIR system for the domain of HRCT images of the lung, physicians do not find this interaction too onerous since the boundary surrounding a pathology bearing region does not have to be precise. But in our new domain, a liver image database, that is unfortunately not the case. The boundaries supplied by the physician must correspond precisely to the outline of the liver or to the boundary of a pathology bearing region inside the liver. To meet this demand, we have developed a new user interaction framework for semi-automatic boundary extraction. All that a physician has to do is to click on a couple of pixels on the boundary to be extracted. The system then tries its best to extend the boundary as far as possible, sometimes even extracting the entire contour correctly. When errors occur, all that the physician is called upon to do is to click on where a correction to the boundary needs to take place. In this manner, an entire boundary can be specified with very little input from the human, which is a most important consideration with physicians as he/she can hardly be expected to click on every boundary point.","PeriodicalId":190569,"journal":{"name":"Proceedings IEEE Workshop on Content-Based Access of Image and Video Libraries (CBAIVL 2001)","volume":"367 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2001-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122843224","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 affective content is viewed as the amount of feeling/emotion contained in and mediated by a video toward a viewer. The ability to automatically extract video content of this nature will lead to a high level of personalization in broadcast delivery to private users, as well as considerably broadening the possibilities of efficiently handling and presenting large amounts of audio-visual data stored in emerging video databases. The technique we have developed uses the so-called \"dimensional approach to affect\" concept underlined by psychophysiology studies. Our computational method sets to represent the affective content as feature points in the so-called 2D emotion space. We manage to obtain time curves that represent the two affect dimensions (arousal and valence) for a video, considered respectively, from low-level video characteristics. Combining the two time curves results in the so-called affect curve that is regarded as a reliable representation of transitions from one feeling to another along a video, as perceived by a viewer. We illustrate the success of our technique on excerpts taken from an action movie and a typical soccer game, respectively.","PeriodicalId":190569,"journal":{"name":"Proceedings IEEE Workshop on Content-Based Access of Image and Video Libraries (CBAIVL 2001)","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2001-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121036670","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}
