Bilinear Interpolation Dynamic Histogram Equalization for Fog-degraded Image Enhancement

摘要

The images degraded by fog suffer from poor contrast. In order to enhance the contrast, a fog degraded image contrast enhancement method based on Bilinear Interpolation Dynamic Histogram Equalization is proposed. First, the original image is divided into some same size sub-images. Second, the histogram of each sub-image is partitioned into sub-histograms without domination. Third, the new dynamic ranges are allocated for sub-histograms. Finally, HE and Bilinear Interpolation are respectively implemented to the image. Experimental results show that the proposed method give better performance as compared with some conventional algorithms.
