This paper describes a new method for iris segmentation using HSI and RGB color spaces. The outer and inner boundaries of the iris are extracted using the k-means unsupervised clusterization method. For the outer boundary detection the best results is obtained using as input variables of the clusterization method the red and green components of the RGB space. The final outer boundary is detected through...
This study proposed to use wavelet transfer to acquire image hue and value as image features, and use Back-propagation Neural Network Fuzzy Clustering analysis to recognize type of textile texture. Firstly, the RGB color space of original color image is transferred to HSV color space; secondly, wavelet transfer is applied to obtain vertical, horizontal and diagonal images of hue and value, and compute...
