IMAGE TARGET IDENTIFICATION METHOD AND APPARATUS

WIPO Patent Application WO/2019/000653

A1

The invention discloses an image target identification method and apparatus. The image target identification method includes the steps of: S1, conducting binary processing for each pixel point in an image, and dividing the pixel points into effective pixel points and background points; S2, setting the magnitude of a third threshold according to the total number of pixel points of the image and the size scope of a target to be identified, comparing the number of effective pixel points in the connected area in a binary picture with the third threshold, setting the pixel points in the area as background points if the number is smaller than the third threshold so as to remove the area; S3, determining an external connecting rectangle frame of the remaining connected areas to form a framing area; and S4, taking connected areas with overlapping framing area as a combined integral area, and determining an external connecting rectangle frame of the integral area. In the image, the image content in the external connecting rectangle frame is identified as a target. The target identification method can effectively identify each target objects in the image with low contrast degree.
