Method and apparatus for object classifier generation, and method and apparatus for detecting object in image

摘要

The present invention provides method and apparatus for object classifier generation, and method and apparatus for detecting object in image. The method for generating a two-cell structure feature descriptor of a two-cell structure composed of a center cell and a neighbor cell in an image region, wherein the neighbor cell is one of eight cells around and adjacent to the center cell, the method comprising: calculating step for calculating statistics of gradients in the center cell and the neighbor cell respectively; and comparing step for comparing the calculated statistics of gradients in the center cell and the neighbor cell, so as to obtain a two-cell structure feature descriptor for describing the feature of the two-cell structure, and;wherein the two-cell structure feature descriptor is one bit binary value.
