报告摘要：

In pattern recognition and 3D computer vision, corresponding points between two images at low level are often the basis for object matching or identification at high level. Finding corresponding points from two images is usually based on the local image content surrounding the points under consideration. Early methods use simple template matching which may be computationally time consuming and sensitive to noise, and variation in illumination and view direction. Local image descriptor is a vector contains features derived from an image patch centered at a given point. It aims to provide translation, rotation and/or scaling invariant features for fast and reliable matching. It has been studied for about 14 years by researchers. This talk gives an overview of local image descriptors and some sample applications.
