In a typical computer vision application, such as video event detection, the “meaningful” information is fundamentally represented by pre-defined features, which determine the appropriate analytical methodologies in the following processing phases. Based on the uncompressed low-level image characteristics, such as colour, intensity and spatial positions, the features used for event detection in this...
According to the color and geometric properties of traffic signs in China, an efficient algorithm of the segmentation and detection of yellow traffic signs in natural scenes is proposed in this paper. Firstly, the image segmentation algorithm based on RGB model is improved and applied on segmenting yellow traffic signs in natural scenes. Then, the detection algorithm based on the shape of the traffic...
