The ICDAR 2021 Time-Quality Binarization Competition assessed the performance of 12 new and 49 other previously published binarization algorithms for scanned document images. Four test sets “real-world” documents with different features were used. For each set, top twenty in quality resulting two-tone images had their average processing time presented, yielding an account complexity.

In optical character recognition and document image analysis skew is introduced in coming documented image. Which degrade the performance of OCR and image analysis system so to detection and correction of skew angle is important step of preprocessing of document analysis. Many methods have been proposed by researchers for the detection of skew in binary image documents. The majority of them are...

Skew detection and correction is very important task before pre-processing of an image and it is a major problem in scanned documents, if it not detected correctly it will lead wrong result in future during image analysis. During the scanning of the document, skew is being often introduced in the document image. To measure the processed time and speed taken by skew detection algorithm, the Fast...
