While the visual rendering of map data is probably the first thing catching somebody's eyes e.g. in a route planning application, the actual usability is heavily dependent on the ability to efficiently search for textual information in the map data. In ...

It's very popular to mark the concerned regions on a document using a mark pen. How to detect the marked regions in the scanned document images is a difficult problem. In this paper, an approach to solve the above problem is proposed. First, the color ...

In this paper, we present an image processing tool that supports efficient image feature extraction and pre-processing developed in the context of a computer-aided detection (CAD) system for lung cancer nodule detection from CT images. We outline the ...

In this paper, a simple but efficient approach for blind image splicing detection is proposed. Image splicing is a common and fundamental operation used for image forgery. The detection of image splicing is a preliminary but desirable study for image ...

Several approaches to real-time video object tracking are reviewed. A new alternative approach for fast real-time object tracking based on colour thresholding is presented. Tracking is performed on non-rigid objects in a sequence of video frames based on ...

In this paper a new feature called crosscount for document analysis is introduced. The feature crosscount is a function of white line segment with its start on the edge of document images. It reflects not only the contour of image, but also the ...
