Embodiment Construction

[0027] In the following description, specific details such as specific system structures and technologies are presented for the purpose of illustration rather than limitation, so as to thoroughly understand the embodiments of the present invention. It will be apparent, however, to one skilled in the art that the invention may be practiced in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.

[0028] figure 1 The implementation flow of the image-based target detection method provided by the embodiment of the present invention is shown, and the details are as follows:

[0029] In S101, a classifier of a cascaded structure composed of multiple binary trees is generated, and the binary tree is characterized by pixel intensity contrast.

[0030] In the embodiment of the present invention,...

Abstract

The invention is suitable for the technical field of computer vision, and provides an image-based target detection method and apparatus. The method includes the following steps: generating a classifier of a cascade structure formed by multiple binary trees, the binary trees taking pixel intensity contrasts as features; conducting image traversal through sliding windows, and obtaining multiple window images; inputting the pixel intensity contrast features of the window images into the classifier; if there is one window image that passes the classifier and an output classification result is not less than a preset threshold value, determining that the window image includes a detection target; and if the classification result of the window image at any grade of the classifier is smaller than the preset threshold value, determining that the window image does not include a detection target. According to the invention, the detection rate of target detection for images is effectively increased, and the false detection rate is reduced.

Description

technical field [0001] The invention belongs to the technical field of computer vision, in particular to an image-based target detection method and device. Background technique [0002] Various places such as shopping malls, shops, hospitals, passenger stations, etc. generally need to count the number of migrants. Real-time traffic flow information is of great significance for estimating the rent level of shopping malls, store operations, traffic flow during golden holidays, traffic flow of public service agencies during peak periods, and store location selection. Using the statistics of people flow data, managers can rationally dispatch manpower and material resources, rationally allocate resources, and determine the people flow control plan, so as to obtain the best operating results. [0003] The basis of people counting is to use faces, heads or limbs as detection targets, so as to realize people counting in surveillance images, but the inventors found that existing tar...
