If we know some properties of the image, than thresholding process only needs to ensure this property is satisfied. In a printed text image, if we know the ratio of area between the sheet and character, then we can choose satisfied threshold value

This paper presents the segmentation algorithm used for localization of iris for the development of robust iris recognition algorithms for biometric process. Iris localization plays a vital importance in iris identification. The method determ
