Our work belongs to this last approach. More particularly, we proposed a detector which uses the constrast 1 . As variations and thus contrasts exist at almost any scale in an image, we must use a multiresolution framework. A Model of Saliency-Based Visual Attention for Rapid Scene Analysis . One of the most basic and widely recognized visual feature is color.
Humans exhibit four characteristic types of eye motion.
Saccadic movements are high speed ballistic motions that center a target in the field of view. This is a computationally inexpensive means to rule out regions which are unlikely to contain faces or hands. L. Itti, C. Koch, and E. Niebur.
