Abstract

In designing page segmentation systems for documents with complex background and poor illumination, separating the background from the objects (text and images) is very crucial for the success of such system. The new local based neural binarization technique developed by the authors will be used to extract the objects from document images with complex backgrounds. This algorithm uses statistical and textural feature measures to obtain a feature vector for each pixel from a window of size (2n + 1) × (2n + 1) , where n ≥ 1 . These features provide a local understanding of pixels from their neighbourhoods making it easier to classify each pixel into its proper class. A Multi-Layer Perceptron Neural Network (MLP NN) is then used to classify each pixel in the image. The results of thresholding are then passed to a block segmentation stage. The block segmentation technique developed is a feature-based method that uses a Neural Network classifier to automatically segment and classify the image contents into text and halftone images. The results of page segmentation are then ready to be passed into an OCR system that will convert the text image into a format the can be stored and modified.
