Vision-based Vehicle Detection in Real Traffic Environment Using Fast Wavelet Transform and Kalman Filter

摘要

A new vision-based approach for robust vehicle detection is addressed in this study. First, fast wavelet transform (FWT) is proposed to extract image texture, while grey level co-occurrence matrix (GLCM) is employed to measure and analyze the extracted texture. Then, vehicles can be extracted because the vehicle sections and the shadow sections have different kAiures in the foreground image. Moreover, we put forward the state and observation matrixes of Kalinan filter which can be used to track vehicles under complicated traffic scenes. Experimental results in real traffic scenes show that the proposed methods are effective and efficient.
