Abstract

The invention discloses a region identification method and device, and belongs to the field of image processing. The region identification method comprises that binaryzation is carried out on a text region to obtain a binary text region which comprises multiple characters in the same row; a histogram of the binary text region is calculated according to the vertical direction, and the histogram comprises accumulated values of horizontal coordinates and foreground color pixel points of pixel points in each column; and according to distribution information of the accumulated values in the histogram, a character region of characters in the text region is identified. Thus, the problem that positioning of a text region is low in accuracy in the prior art is solved, and the character region can be accurately positioned according to distribution information of the accumulated values of the foreground color pixel points in the histogram.

Description

technical field [0001] The present disclosure relates to the field of image processing, and in particular to an area recognition method and device. Background technique [0002] In the field of image processing, before the terminal recognizes the text in the image, the terminal needs to first recognize the character area of ​​the text. [0003] An area recognition method provided in the related art includes: the terminal removes the background in the image, and extracts the foreground image; then identifies the edge of the characters in the extracted foreground image through the edge enhancement technology; determines the The character area of ​​each literal. [0004] In the above solution, since the edge enhancement technology can only provide rough positioning, the accuracy of the character area positioned by the above solution is low. Contents of the invention [0005] In order to solve the problem of low positioning accuracy of character areas in the related art, the...
