Takes an image and divide it into many blocks then examine each block to check if it's background or not and if it's in focus or out of focus.
Parameter | Description |
pNonBlurredBlocks | the array of in focus blocks after applying text blur detector. |
NonBlurredBlocksCount | the number of out of focus blocks after applying text blur detector. |
pBlurredBlocks | the array of out of focus blocks after applying text blur detector. |
BlurredBlocksCount | the number of out of focus blocks after applying text blur detector. |
CombinedTextBlocks | the boundary of text area in the image, that's isn't a background. |
SUCCESS | The function was successful. |
< 1 | An error occurred. Refer to Return Codes. |
This command supports 8,12, 16-bit grayscale images and 24, 32-bit colored images.
