Problems solved by technology

The existing image binarization algorithm usually weights, averages or takes the maximum value of the red component (R value), green component (G value) and blue component (B value) in the RGB value of each pixel Then compare it with the preset threshold to determine whether to set the pixel as a pure black pixel or a pure white pixel. However, it is not easy to find a suitable threshold in this method of uniformly processing the three components of the RGB value, and the image background half In the case of transparency, the effect of image binarization is not ideal, and the background interference cannot be removed, resulting in low accuracy of image recognition

Abstract

The invention discloses an image binarization method and device, an electronic device and a storage medium. The method comprises the following steps of firstly obtaining a plurality of color components of each pixel in a target image, wherein each color component of the plurality of color components corresponds to a preset interval; then determining a binarized pixel value of each pixel accordingto the plurality of color components and the preset interval; then converting the target image into a binary image according to the binarized pixel value. By adopting the embodiment of the invention,the background interference can be effectively removed, thereby improving the accuracy of image recognition.

Description

technical field [0001] The invention relates to the field of image processing, in particular to an image binarization method, device, electronic equipment and storage medium. Background technique [0002] At present, image recognition occupies an important position in the fields of mobile games, face recognition, and driverless driving. Among them, the real-time captured target image is usually matched with the template image of known image elements. When the target image matches the template image When , it is determined that the image elements in the target image are the same as those in the template image, so as to achieve the purpose of identifying the target image. The mainstream image matching methods include histogram matching algorithm, image template matching algorithm and so on. Although these algorithms have high matching efficiency and a wide range of applications, it is still undeniable that these algorithms have a high misrecognition rate. When the accuracy re...
