Abstract

The invention is suitable for the image identification field, and provides an image identification method. A pixel in an image to be identified is obtained; when the pixel value of the pixel is smaller than or equal to the pixel values of a plurality of pixels in a preset area, the pixel is determined as a target pixel, wherein the preset area is an area which takes the pixel as a center point; and through the determined target pixel, an image of a head area in the image to be identified is formed.

Description

technical field [0001] The invention belongs to the field of image recognition, in particular to an image recognition method and device. Background technique [0002] With the increasing urbanization, the urban population continues to expand, and the activities of groups increase day by day. The safety of the crowd has become a social problem, so people counting has become a research hotspot. [0003] Usually, people counting will use the technology of head recognition to count the head after recognition. The existing head recognition technology uses a color model to identify the head. In the preparatory work, a large number of head samples need to be collected for learning, such as the type of clothing, dress, hairstyle, hat and head decoration. [0004] Existing head recognition technologies use color models to recognize head images. If similar colors or different dresses and hairstyles appear on the head, it will lead to misjudgment and low accuracy of image recognition....
