Abstract

The present invention provides a real-time translation method of video captions. The method comprises: performing multi-channel extraction of original images captured in video, and obtaining a plurality of single-channel images; based on the MSER algorithm, extracting MSER areas of the original images and the single-channel images; calculating the local contrast between each MSER area and a background area, determining whether the corresponding MSER areas are filtered or not according to each local contrast; determining the boundary key points of each MSER area; taking the boundary key points as classification screening characteristics, performing classification screening of the each residual MSER area after filtering through a trained SVM, and obtaining a test area; according to a distance between each two adjacent test areas on the vertical direction, performing test distinguishing of each test area, and according to a distance between each two adjacent test areas on the same test line, performing classification of each test area of the same test line; and performing real-time translation of video captions based on each test area after classification.

Description

technical field [0001] The invention belongs to the field of image processing, and in particular relates to a method for real-time translation of video subtitles. Background technique [0002] In recent years, text detection and recognition in natural scene images has become a popular research topic in the fields of computer vision, pattern recognition, and even document analysis. Researchers have proposed a large number of new ideas and methods for extracting textual information from natural scene images. However, currently, when translating video subtitles, real-time translation of video subtitles cannot be achieved due to the high time complexity of extracting text information from images. Contents of the invention [0003] The invention provides a method for real-time translation of video subtitles to solve the current problem that the real-time translation of video subtitles cannot be realized due to the high time complexity of extracting text information from images...
