Gradual and random binarization of gray-scale holograms.

چکیده
A new method called gradual and random binarization to binarize gray-scale holograms, based on an iterative algorithm, is proposed. The binarization process is performed gradually, and the pixels to be binarized are chosen randomly. Errors caused by this operation are spatially diffused. A comparison with other established methods based on error diffusion, direct binary search, and iterative stepwise quantization shows that the gradual and random binarization method achieves a very good compromise between computational complexity and reconstruction quality. Optical reconstructions are presented.

Implementation of Bernsen’s Locally Adaptive Binarization Method for Gray Scale Images
In digital image processing, binarization (two-level thresholding) is a commonly used technique for image segmentation. It is the process of converting a gray scale image to a binary image. Furthermore, binarization methods are divided into two groups as global binarization and locally adaptive binarization. A number of binarization techniques have been proposed over the years. Bernsen’s method...

This paper presents an evaluation of eleven locally adaptive binarization methods for gray scale images with low contrast, variable background intensity and noise. Niblack’s method with the addition of the postprocessing step of Yanowitz and Bruckstein’s method added performed the best, and was also one of the fastest binarization methods. Keywords— Locally adaptive binarization, Thresholding, ...
متن کاملBinarization of noisy gray-scale character images by thin line modeling
In this paper, we propose two new methods for the binarization of noisy gray-scale character images obtained in an industrial setting. These methods are different from other conventional binarization methods in that they are specially designed to detect only character-like regions. They exploit the fact that characters are usually composed of thin lines (strokes) of uniform width. We first mode...
متن کاملEnhancement of Image Resolution by Binarization
Image segmentation is one of the principal approaches of image processing. The choice of the most appropriate Binarization algorithm for each case proved to be a very interesting procedure itself. In this paper, we have done the comparison study between the various algorithms based on Binarization algorithms and propose a methodologies for the validation of Binarization algorithms. In this work...
متن کاملUsing Irregular Pyramid for Text Segmentation and Binarization of Gray Scale Image
Compared to binary images that most text extraction methods work on, gray scale images provides much more information for the extraction task. On the other hand complication also arises in determining the subject textual content from its background region (ie. thresholding) before the actual text extraction process can begin. Differing from the usual sequence of processes where document images ...
