Document Image Quality Assessment

Document Image Quality Assessment (DIQA) is an important sub-task in the field of computer vision, focusing on evaluating the quality of document images. This task aims to automatically detect and quantify various factors of quality degradation in document images, such as blurriness, noise, skew, etc., to ensure their readability and usability. DIQA has broad application value in areas like document digitization, OCR recognition, and archive management, effectively enhancing the accuracy and efficiency of subsequent processing.
