In this paper, we proposed an efficient multiresolution decomposition framework for iris texture feature extraction, which has superior directionality and localized frequency partition. It consists of an improved circular symmetric filter bank followed by a directional filter bank. In our iris recognition system, we adopt a novel non-polar coordinate normalization strategy as iris preprocessing method...
In this paper, we propose a new computer aided diagnosis method for prostate cancer detection in ultrasound image. With multi resolution autocorrelation texture features and clinical features such as location and shape of tumor, we could maintain high specificity with high sensitivity for prostate cancer detection. Multi resolution autocorrelation can detect cancer suspicious region efficiently with...
