METHOD AND APPARATUS FOR DETECTING GENERALIZED PASSERBY
First Claim
1. A method for detecting a generalized passerby, comprising:
- acquiring an input image;
determining whether a preset common feature of a wheel exists in the input image;
selecting an image window at left side or right side or upper side of a center of a region where the preset common feature of the wheel is located in a case that the preset common feature of the wheel exists in the input image; and
inputting the selected image window into a preset upper-body classifier, detecting whether an upper body of a passerby exists in the selected image window and outputting a first detection result,wherein the preset upper-body classifier is generated by training with a preset common feature of a generalized passerby, the preset common feature of the generalized passerby comprises a common feature of a human body, and the preset common feature of the wheel comprises a circle feature and an oval feature.

6. An apparatus for detecting a generalized passerby, comprising:
-
an acquiring unit configured to acquire an input image; and a first detecting unit configured to determine whether a preset common feature of a wheel exists in the input image, select an image window at left side or right side or upper side of a center of a region where the preset common feature of the wheel is located in a case that the preset common feature of the wheel exists in the input image, input the selected image window into a preset upper-body classifier, detect whether an upper body of a passerby exists in the selected image window and output a first detection result, wherein the preset upper-body classifier is generated by training with a preset common feature of a generalized passerby, the preset common feature of the generalized passerby comprises a common feature of a human body, and the preset common feature of the wheel comprises a circle feature and an oval feature. - View Dependent Claims (7, 8, 9)
