Abstract
Aspects of the present invention disclose a method, computer program product, and system for image processing. The method includes one or more processors generating a first set of binary images from a first image based on a first color attribute value range associated with a textual object presented in the first image. The method further includes one or more processors recognizing a first set of candidates for the textual object from the first set of binary images. The method further includes one or more processors determining a first appearance frequency of a first candidate in the first set of candidates. In response to determining that the first appearance frequency exceeds a first frequency, threshold he method further includes one or more processors determining that the first candidate is a first recognition result for the textual object in the first image.
