How to get qualified iris image is one of the difficulties in iris recognition. It also restricts the extensive application of iris recognition. Thus, how to quickly and easily collect an iris image with high resolution and rich texture plays a vital role for the speed and accuracy of an iris recognition algorithm. In this paper, a qualified status detection and localization algorithm for iris image based on Adaboost is proposed, which can quickly and efficiently detect unqualified iris images, such as inco...
