Degraded Document Image Binarization Using Optical Character Recognition

The proposed OCR algorithm to retrieve the text in the scanned document images. Here the text detection algorithm based on two machine learning classifiers: one allows generating candidate word regions and the other filters out non-text ones. The extract connected components (CCs) in images by using the maximally stable extremal region algorithm. In CC clustering adaboost classifiers are used t...

Image Binarization Based On ICA Approach for Optical Character Recognition

Image binarization plays a vital role in text segmentation which is used in OCR application. Binarization of text in degraded images is a challenging task due to the variations in colour, size, and font of the text and the results are often affected by complex backgrounds, different lighting conditions, shadows and reflections. A robust solution to this problem can significantly enhance the acc...

Pornographic Image Filtering Using Skin Recognition Methods

In this paper, we describe various skin detection methods, image filtering methods and comprehensive comparative study among these methods proposed to detect adult classified images. It is based on concept of Computer Vision algorithms and pattern recognition techniques. First the images are changed to identify areas with low color intensity by the color model. In the next part of the proposed ...

Image Normalization and Preprocessing for Gujarati Character Recognition

Pattern recognition has been an important area in computer vision applications. In the case of a planar image, there are four basic forms of geometric distortion caused by the change in camera location: translation, rotation, scaling and skew. So far, a number of methods have been developed to solve these distortions, such as moment invariants’, Fourier descriptor, Hough transformation, shape m...
