Binarization of Black/Green Board Data Captured by Mobile 1 Puneet, 2 Naresh Kumar Garg 1 Department of Computer Science & Engineering, GRDIET, Bathinda, Punjab, India 2 Department of Computer Science & Engineering, GZSPTU Campus, Bathinda, Punjab, India __________________________________________________________________________________________ Abstract: This paper deals with the binarization of mobile captured images from the black/green board images in which text is segment from the degraded images of the black/green board and get the 92.589% accuracy. In proposed technique first apply the enhancement technique to eliminate the distortion in background of given image. After enhancement image is segmented in 3x3 parts and computed locally threshold value. Binarization is the active area of research in academic because it is the important phase of the pre-processing in the field of pattern recognition and the rate of recognition is highly dependent on the accuracy of binarization.

Binarization of camera-captured document using A MAP approach

Document binarization is one of the initial and critical steps for many document analysis systems. Nowadays, with the success and popularity of hand-held devices, large efforts are motivated to convert documents into digital format by using hand-held cameras. In this paper, we propose a Bayesian based maximum a posteriori (MAP) estimation algorithm to binarize the camera-captured document image...

Binarizing Business Card Images for Mobile Devices

Business card images are of multiple natures as these often contain graphics, pictures and texts of various fonts and sizes both in background and foreground. So, the conventional binarization techniques designed for document images can not be directly applied on mobile devices. In this paper, we have presented a fast binarization technique for camera captured business card images. A card image...

Robust Binarization of Stereo and Monocular Document Images Using Percentile Filter

Camera captured documents can be a difficult case for standard binarization algorithms. These algorithms are specifically tailored to the requirements of scanned documents which in general have uniform illumination and high resolution with negligible geometric artifacts. Contrary to this, camera captured images generally are low resolution, contain nonuniform illumination and also posses geomet...

Foreground-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...
