SYSTEM OF OBJECT DETECTION |
摘要 |
In a system of object detection, a color detector detects at least one image region in an input image having a color specifically pertinent to the object under detection, thereby obtaining an object width. A dynamic down-sampling unit adaptively performs down-sampling on the detected image region using a generated down-sampling factor according to the object width. An image feature generator receives the down-sampled image and accordingly generates image features for describing the object under detection, and a cascade of classifiers then operates on the image features. |

1. A system of object detection, comprising:
a color detector operable to receive an input image and configured to detect at least one image region in the input image having a color specifically pertinent to the object under detection, thereby obtaining an object width; a dynamic down-sampling unit configured to adaptively generate a proper down-sampling factor according to the object width, and perform down-sampling on the detected image region using the generated down-sampling factor, thereby generating a down-sampled image; an image feature generator operable to receive the down-sampled image, and accordingly configured to generate image features for describing the object under detection; and a cascade of classifiers configured to operate on the image features. |
