Abstract

The invention provides a text picture filtering method and device and electronic equipment, and relates to the technical field of image processing, and the method comprises the steps: converting a to-be-filtered color picture into a color space model; determining a text color in the to-be-filtered color picture as a target color, and obtaining a color space range value of the target color; and performing color conversion on the color space model according to the color space range value of the target color to obtain a text picture corresponding to the to-be-filtered color picture. According tothe invention, the text picture filtering accuracy is improved.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a text picture filtering method, device and electronic equipment. Background technique [0002] With the explosive development of the information age, more and more image data are disseminated through various channels, and the ensuing challenge is how to quickly and effectively obtain useful information from massive data centers. The text in natural scenes is all-encompassing, including landscapes, characters, and buildings. How to obtain valuable text images from numerous pictures for text detection and text recognition is a problem that has attracted much attention in the field of computer vision. The existing text image filtering technology filters the text in the image based on the image histogram of the image. Because the color values ​​in some images are not absolute values, the accuracy of the existing text image filtering technology is low. Contents of ...
