Abstract: An overtaking vehicle warning system includes an image photographing unit attached to a front of a vehicle to photograph an object in a forward direction of the vehicle; a driving unit receiving image data from the image photographing unit to select a region of interest, extracting a feature of a vertical edge from the region of interest to compare the feature of the vertical edge with a feature of a previous frame, and generating warning generating signal when a matched feature is equal to or greater than a threshold value; and a warning unit receiving the warning generating signal to generate an overtaking vehicle warning signal. An edge region is searched from an image photographed in the forward direction to obtain a predetermined feature, and warning is generated with respect to the overtaking vehicle by tracking a vehicle having the corresponding feature.

Abstract: Video processing in general and image processing in particular is a very complex process. This is more so when the analysis is required to extract information from the images for providing of the same directly or indirectly to the users. This additional complexity is due to the direct competition with users who are used to analyzing of the images both syntactically and semantically. One of the ways to contain the complexity of image analysis is to exploit the domain semantics during image processing. A system and method to help in semantics based image processing involves the identification of one or more domain relevant semantic hierarchies and using of the same during image processing.
