METHOD, COMPUTER-READABLE MEDIUM, AND ELECTRONIC DEVICE FOR IMAGE TEXT RECOGNITION - A simplified explanation of the abstract

This abstract first appeared for US patent application 18354726 titled 'METHOD, COMPUTER-READABLE MEDIUM, AND ELECTRONIC DEVICE FOR IMAGE TEXT RECOGNITION

Simplified Explanation

The patent application describes a method for recognizing text in an image using image processing techniques.

  • The method starts by converting the image into a grayscale image.
  • The grayscale image is then segmented into different layers based on the grayscale values of the pixels.
  • Image erosion is performed on each layer to obtain a feature layer that contains connected regions.
  • The feature layers are overlaid to create an overlaid feature layer with connected regions.
  • The connected regions on the overlaid feature layer are dilated in a specific direction to identify text regions.
  • Text recognition is then performed on the text regions to extract the recognized text corresponding to the image.


Original Abstract Submitted

An image text recognition method includes converting an image into a grayscale image, and segmenting, according to layer intervals to which grayscale values of pixels in the grayscale image belong, the grayscale image into grayscale layers with one corresponding to a layer interval, performing image erosion on a grayscale layer to obtain a feature layer corresponding to the grayscale layer, the feature layer including at least one connected region; overlaying feature layers to obtain an overlaid feature layer, the overlaid feature layer including connected regions; dilating connected regions on the overlaid feature layer according to a preset direction to obtain text regions; and performing text recognition on the text regions on the overlaid feature layer to obtain a recognized text corresponding to the image.
