Traffic light recognition is a key technology for intelligent vehicles and Advanced Driver Assistance Systems (ADAS). This paper proposes a multi-feature fusion based real-time traffic light recognition algorithm for intelligent vehicles. In the region of interest determined by the vanishing line, technologies including color segmentation, blob detection, and structural feature extraction are employed...
An arbitrary shape region of interest (ROI) coding is presented for scalable wavelet video codec in this paper. The framework of ROI-based wavelet coding is shown in the Figure 1. First, by segmenting and tracking of the original video, we can obtain the region of interest for each frame. The shapes information of the ROI is given in the way of two-value template (MASK). The ROI can be one or more...
In this paper, we present a biased sampling strategy for object class modeling, which can effectively circumvent the scene matching problem commonly encountered in statistical image-based object categorization. The method optimally combines the bottom-up, biologically inspired saliency information with loose, top-down class prior information to form a probabilistic distribution for feature sampling...
