virtual L_INT LBitmap::TextBlurDetector(pNonBlurredBlocks, NonBlurredBlocksCount, pBlurredBlocks, BlurredBlocksCount, CombinedTextBlocks)
the array of in focus blocks after applying text blur detector.
the number of out of focus blocks after applying text blur detector.
the array of out of focus blocks after applying text blur detector.
the number of out of focus blocks after applying text blur detector.
the boundary of text area in the image, that's isn't a background.
