The potential of these filters largely depends on the apriori knowledge about the type of noise corrupting the images. This makes the standard filters to be application specific. The widely used proximity based filters help in removing the noise by over-smoothing the edges. On the other hand, sharpening filters enhance the high frequency details making the image non-smooth. In this paper, we have introduced a new finite impulse response (FIR) filter for image restoration where, the filter undergoes a learning procedure. The FIR filter coefficients are adaptively updated based on correlated Hebbian learning. This algorithm exploits the inter pixel correlation in the form of Hebbian learning and hence performs optimal smoothening of the noisy images. The proposed filter uses an iterative process for efficient learning from the neighborhood pixels. Evaluation result shows that the proposed FIR filter is an efficient filter compared to average and Wiener filters for image restoration applications","PeriodicalId":421826,"journal":{"name":"Proceedings of the Fifth IEEE International Symposium on Signal Processing and Information Technology, 2005.","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126383661","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 present a new image-based approach to infer 3D human structure parameters from uncalibrated video. The estimation is example based. First, we acquire a special motion database through an off-line motion capture process. Second, given an uncalibrated motion video, we abstract the viewpoint and then the silhouettes database associated with 3D poses is built by projecting each data of the 3D motion database into 2D plane. Next, with the image silhouettes, the unknown structure parameters are inferred by performing a similarity search in the silhouettes database. We pay more attention on how to retrieving 3D body pose by matching 2D silhouette based on shape context. Through a lot of experiments, the results we got are really satisfying. To accelerate the process of calculating the distance in shape context, we use PCA (principal components analysis) to reduce the computation of complexity. We use trampoline sport, which is an example of complex human motion, to demonstrate the effectiveness of our approach and compare the results with those obtained with Hu moments method","PeriodicalId":421826,"journal":{"name":"Proceedings of the Fifth IEEE International Symposium on Signal Processing and Information Technology, 2005.","volume":"138 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121365794","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}
