The groups of correlated images exist in many practical cases. These are, for example, the components (spectrum bands) of the multispectral images, the sequences of the computer tomography images, video sequences from surveillance TV cameras with fixed spatial position, video information from TV microscopes, etc. The new Hierarchical Transform is reversible. It results in high decorrelation of the processed groups of images and ensures high power concentration in the former in the group, called “eigen”. The decorrelation, achieved through the AHT is close in efficiency to the “classic” PCA, but has lower computational complexity. Besides, the structure of the AHT algorithm is extremely suitable for parallel processing. In the paper are also given some experimental results for the algorithm modeling, applied on sequences of CT images. The computational complexity of the AHT algorithm is compared with this of the classic PCA.","PeriodicalId":144044,"journal":{"name":"2013 11th International Conference on Telecommunications in Modern Satellite, Cable and Broadcasting Services (TELSIKS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2013-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128482443","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 proposed scheme is both multi-Tb/s and beyond 100 Tb/s enabling technology.

The Selva's interpolator has been used for design and implementation of fractional delay filters. The filter has been designed using an approximate prolate window. However, the frequency response of the filter has not been analyzed. In this contribution, we analyze the frequency response of Selva's interpolator and we compare it to the Farrow structure. Finally, we show that Selva's interpolator can have very selective frequency domain performance, and thus it can be effectively used in some DSP applications.","PeriodicalId":144044,"journal":{"name":"2013 11th International Conference on Telecommunications in Modern Satellite, Cable and Broadcasting Services (TELSIKS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2013-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127731861","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}
