ABSTRACT: To process the traffic
monitoring image, a local Histogram Equalization method based on fuzzy
mathematics was proposed in this paper. In this paper, firstly, we define a
function to measure the similarity degree of two images. Then, a suitable
Gaussian fuzzy distribution function was chose to generate a 3 × 3 matrix of
influential factors. In order to reduce the artificial boundaries, we combined
the 3 × 3 influential matrix with a 3 × 3 smooth filter matrix to get the final
smooth-influ- ence matrix. Finally, the smooth-influence matrix was used to
process the center block image. The simulation results demonstrated that the
proposed method can reduce time consumption while improving the image contrast
and can get satisfactory results.
