Edges in infrared image usually cause serious false alarms in single frame infrared small target detection. So a novel edge-preserving background estimation method is proposed for small target detection to attenuate this problem. First we will introduce the patch similarity feature of infrared image. Then, patch similarity of infrared image is utilized to formulate edge-preserving infrared background...
This paper investigates precise pupil center localization in low-resolution images. Being an essential preprocessing step in many applications such as gaze estimation, face alignment as well as human-computer interaction, robust, precise, and efficient methods are necessary. We present a method for accurate eye center localization operating with images from simple off-the-shelf hardware such as webcams...
