The overall system involves the relative spectral transform-perceptual linear prediction for spectrogram image extraction, cosine similarity measure for feature matching, dynamic Hilbert curve for spectrogram routing, and Gaussian mixture model for 1-D spectrogram classification. As an example of our approach, results for honk, dolphin, and whale classification are presented. This method works well on a wide variety of bio-sounds, especially for the highly self-repeated ones. Applications of this approach include biological signal analysis and spectrogram library establishment.","PeriodicalId":236574,"journal":{"name":"2010 2nd International Conference on Image Processing Theory, Tools and Applications","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132638545","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}

In this paper, we describe a stroke feature extraction method which will used in the lettrine indexing. A lettrine is a letter decorated who appear at the beginning of a chapter or a paragraph in ancient books. It's principally composed of strokes. This method is developed with the goal to characterize for indexing them by content using these particular components. We thus use strokes instead of pixels as elementary component. This study is innovative and first results are interesting.

These objects are rich in information, such as human face. They should be coded with higher quality than unfocused ones as in foveated video coding, for which eye tracking can serve as a preliminary step. We show that human gaze points often cover only a very small area of the screen, even less than 10%, providing great opportunities to save much more bit rate. Gaze points from a number of subjects watching a scene can be represented compactly in the proposed box diagram, another contribution from this work, that can give simple description of the scene just in a one diagram.","PeriodicalId":236574,"journal":{"name":"2010 2nd International Conference on Image Processing Theory, Tools and Applications","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129231289","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 input H.264/AVC stream is fully decoded by the transcoder. Macroblock coding modes are extracted from the input stream and are reused to encode the output stream. A set of new motion vectors is computed from the input stream coded motion vectors, and are mapped to either the hierarchical B-frame or zero-delay referencing structures employed by H.264/SVC. These new motion vectors are further subjected to a 3 pixel refinement. As a result, a significant decrease in computational complexity is achieved, while maintaining a close to optimum compression efficiency.","PeriodicalId":236574,"journal":{"name":"2010 2nd International Conference on Image Processing Theory, Tools and Applications","volume":"108 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133177486","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}

Paper's main motif is inferring information about planer movement of the head using a video camera and transforming this motion to the pixel coordinate system of the display so as to control the position of mouse pointer. Iterative sparse optical flow algorithm computes the pattern of apparent motion between sequential facial image frames captured by the webcam. Adaboost based Cascaded Harr classifier is used to detect face and eye across frames and we have given special attention towards the issues involving drawback regarding misdetection of tilted faces in the image frame inspite of training our datasets with tilted facial images. Left/Right eye blink is used to control the clicking event of mouse. Blink of eye is modelled by fitting the trained data using Spline and Gaussian curve which determines the likelihood function to determine the posterior probability. This work is motivated by the need to design an affordable real-time system in the interest of a large serving community.","PeriodicalId":236574,"journal":{"name":"2010 2nd International Conference on Image Processing Theory, Tools and Applications","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123282543","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}
