COLLABORATIVE TEXT DETECTION AND RECOGNITION

摘要

Various embodiments provide methods and systems for identifying text in an image by applying suitable text detection parameters in text detection. The suitable text detection parameters can be determined based on parameter metric feedback from one or more text identification subtasks, such as text detection, text recognition, preprocessing, character set mapping, pattern matching and validation. In some embodiments, the image can be defined into one or more image regions by performing glyph detection on the image. Text detection parameters applying to each of the one or more image regions can be adjusted based on measured one or more parameter metrics in the respective image region.

1. A system for identifying text in an image, comprising:
at least one processor; and memory including instructions that, when executed by the at least one processor, cause the system to:
receive the image captured by a computing device;detect text in the image using a predetermined set of text detection parameters;identify one or more regions in the image, each of the one or more image regions covered by at least a portion of the detected text;measure, in response to the detected text being recognized, one or more parameter metrics of each of the one or more image regions;adjust, in response to one or more predetermined conditions being met, the text detection parameters or at least one text detection method applying to each image region based on the measured one or more parameter metrics of the respective image region; andapply the adjusted text detection parameters or the adjusted at least one text detection method to the respective image region of the image.
