Metric Rectification to Estimate the Aspect Ratio of Camera-Captured Document Images
Document images from mobile phone cameras and digital cameras suffer from geometric distortion; therefore distortion correction is desired for better character recognition. We propose a method to calculate the aspect ratio of planar documents using 3D perspective projection of quadrangles without using vanishing points. The proposed method is based on estimation of direction of a pair of parall...
متن کاملForeground-Background Regions Guided Binarization of Camera-Captured Document Images
Binarization is an important preprocessing step in several document image processing tasks. Nowadays handheld camera devices are in widespread use, that allow fast and flexible document image capturing. But, they may produce degraded grayscale image, especially due to bad shading or non-uniform illumination. State-of-the-art binarization techniques, which are designed for scanned images, do not...
متن کاملAdaptive Binarization of Unconstrained Hand-Held Camera-Captured Document Images
This paper presents a new adaptive binarization technique for degraded hand-held camera-captured document images. The state-of-the-art locally adaptive binarization methods are sensitive to the values of free parameter. This problem is more critical when binarizing degraded camera-captured document images because of distortions like non-uniform illumination, bad shading, blurring, smearing and ...
متن کاملThe IUPR Dataset of Camera-Captured Document Images
Major challenges in camera-base document analysis are dealing with uneven shadows, high degree of curl and perspective distortions. In CBDAR 2007, we introduced the first dataset (DFKI-I) of camera-captured document images in conjunction with a page dewarping contest. One of the main limitations of this dataset is that it contains images only from technical books with simple layouts and moderat...
متن کاملA Dataset for Quality Assessment of Camera Captured Document Images
With the proliferation of cameras on mobile devices there is an increased desire to image document pages as an alternative to scanning. However, the quality of captured document images is often lower than its scanned equivalent due to hardware limitations and stability issues. In this context, automatic assessment of the quality of captured images is useful for many applications. Although there...
