In this paper, a segmentation-free keyword spotting method is proposed for Bangla handwritten documents. In order to tolerate large variations in handwritten scenarios, we extracted key points based on SIFT key point detector, and the end and intersection points found by morphological operations. Heat Kernel signature (HKS) is used to present the local characteristics of detected key points. Instead...
Although a large number of methods for video text detection and recognition have been proposed over the past years, it is hard to find the best state-of-the-art method because of nonavailability of standard datasets, ground truth, and common evaluation measures. Therefore, in this paper, we propose a semiautomatic system for ground truth generation for video text detection and recognition, which includes...
A web-based system for retrieving imaged documents from a digital library is described in this paper. First, some image preprocessing is performed off-line on the underlying imaged document to extract its word objects. Then, each word object is represented by a string known as its feature code, based on which a feature code file of the corresponding document is constructed. On the web interface side,...
