Abstract

The application discloses a method and a device for recognizing text areas in an image. A specific embodiment of the method comprises: acquiring a color value and position information of each pixelin the image to be recognized; clustering the pixels based on the color value of each pixel, wherein the color values of the pixels in each pixel category are the same or similar; for each pixel category after clustering, determining the contour of each connected area constituted by the pixels in the pixel category to obtain a contour set; and merging the contours based on the color value and position information of each contour in the contour set to obtain respective text areas in the image. The embodiment improves the accuracy of text line sequence recognition in image character recognition.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to the field of pattern recognition technology, and in particular to a method and device for recognizing text regions in an image. Background technique [0002] Optical Character Recognition (OCR), also known as text recognition, refers to the technology of recognizing characters in images. [0003] However, for images with mixed graphics and text, complex typesetting and various styles, the existing character recognition technology can only recognize character lines and characters when recognizing them, but cannot judge the order between character lines and character lines. Suppose the picture to be recognized is as figure 1 As shown, the general OCR system will sort the recognized text from top to bottom and from left to right, so figure 1 The sequence of text recognized in is "Title 1 Chapter 3 Chapter 2 Chapter 4", but actually in the typesetting of the original im...
