B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method and device for text detection in a natural image and a method and system for text information extraction.SOLUTION: A method for detecting a text region in an image including at least one connected component (CC) includes: a TBR detection step 310 for detecting at least one text background region (TBR) from an image; a CC filtering step 320 for ensuring at least one candidate text CC by filtering at least one CC; and a CC grouping step 330 for forming at least one CC group by grouping at least one candidate text CC on the basis of the TBR detected in the TBR detection step and generating at least one text region on the basis of at least one CC group. A location of a text in an image can be promptly and/or accurately shown, and as a result, performance in text detection increases.
