The image processing apparatus detects candidates for the heading region from the image, and defines a predetermined range in the image as a range to be processed. The apparatus further groups the candidates in the range to be processed, based on a feature quantity corresponding to a feature in terms of style of a character string. The apparatus selects a representative group from the resultant groups, and divides the range to be processed, at the position of a candidate belonging to the representative group. The apparatus newly defines each of the portions generated by the division as a range to be processed."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Image processing method and image processing apparatus for extracting heading region from image of document","description":"An image processing apparatus analyzes an image of a document to thereby extract a heading region from the image.
