Abstract
A character recognition method and apparatus are disclosed, relate to the field of image recognition technologies, reduce a calculation time, and increase character recognition efficiency. The method includes: obtaining picture data (110); performing calculation on the picture data by using calculation layers shared by a first classifier and a second classifier, to obtain a first result, where the first classifier is a classifier for recognizing a specific character in the picture data, and the second classifier is a classifier for recognizing whether the picture data is a character picture (120); performing calculation by bringing the first result into remaining calculation layers other than the shared calculation layers in the first classifier, to obtain a first probability corresponding to each character (130); performing calculation by bringing the first result into remaining calculation layers other than the shared calculation layers in the second classifier, to obtain a second probability (140); calculating, based on the first probability and the second probability, a confidence value that the picture data is recognized as each character (150); and outputting a character reco…
