Document Type and Number:
WIPO Patent Application WO/2021/172699
Kind Code:
A1
Abstract:
The present invention relates to a system and a method for determining importance of a text block extracted from an image, the system comprising: a character recognition unit for extracting text from an input image; a character block unit for generating a text block by dividing the extracted text into sentence units; and a calculation unit for extracting a feature from each text block, designating a characteristic for a corresponding text block, and if a value of the designated characteristic for the text block exceeds a preconfigured threshold value, classifying the text block into a corresponding text block to be output. According to the present invention as described above: features may be extracted from a text block generated by recognizing texts included in an image; by performing binary classification on text to be output, via importance calculation for the extracted features, only text that matches the calculated importance from among the texts included in the image may be selected and output; and via linkage with a screen reader, only information necessary for online shopping for a visually impaired person may be provided by voice.
