Abstract

The invention provides an image identification method and apparatus. The method comprises steps of obtaining an image to be processed; according to a preset strategy, obtaining positional information of an edge identifier in the image to be processed; according to the positional information of the edge identifier and a preset shape of a sensitive area, determining the sensitive area in the image to be processed; and identifying an image in the sensitive area by a preset algorithm. The invention firstly determines the sensitive area in a small range by the edge identifier, and then identifies the image in the sensitive area. As the image identification area is narrowed, the image can be rapidly positioned, so that the image identification speed is accelerated, the image identification time is saved, and the image identification efficiency is improved.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image recognition method and device. Background technique [0002] Image processing is the technique of analyzing images with computers to achieve the desired results. Also known as image processing. Image processing generally refers to digital image processing. A digital image refers to a large two-dimensional array obtained by shooting with industrial cameras, video cameras, scanners and other equipment. The elements of this array are called pixels, and their values ​​are called grayscale values. Image processing technology generally includes three parts: image compression, enhancement and restoration, matching, description and recognition. [0003] During the image processing of image extraction, there are usually background interference objects in the imaging area. The existing technology needs to use software processing to perform global sensitive imag...
