This paper describes a new binocular tracking method using Log Polar Mapping (LPM) which approximately represents the mapping of the retina into the visual cortex in primate vision. Using LPM makes it possible not only to obtain both a high central resolution and a wide eld of view, but also to signicantly reduce processing image data. In this paper, LPM is(More)
A new technique for description and recognition of human gestures is presented. First, a method is proposed to represent gestures as an ordered sequence of simple basic motions. It is based on the rate of change of gesture motion direction (referred to as \curvature") that is estimated using optical ow from monocular motion images. Then, proceedings from(More)
