In this paper, we propose an efficient stereo image rectification method using the horizontal baseline. Since the stereo camera is generally manually arranged, there are geometric errors due to the camera misalignment and the differences between the camera internal characteristics. Although the conventional calibration-based stereo image rectification method is simple, it has an opportunity to ...

Image rectification is the process of applying a pair of 2 dimensional projective transforms, or homographies, to a pair of images whose epipolar geometry is known so that epipolar lines in the original images map to horizontally aligned lines in the transformed images. We propose a novel technique for image rectification based on geometrically well defined criteria such that image distortion d...

In this paper we present Document analysis and classification system to segment and classify contents of Arabic document images. This system includes preprocessing, document segmentation, feature extraction and document classification. A document image is enhanced in the preprocessing by removing noise, binarization, and detecting and correcting image skew. In document segmentation, an algorith...

In this paper we study how learning can be used in several aspects of car detection and tracking. The overall goal is to develop a system that learns its surrounding and subsequently does a good job in detecting and tracking all cars (and later pedestrians and bicycles) in an intersection. Such data can then be analyzed in order to determine how safe an intersection is. The system is designed t...
