In view of the histogram equalizing algorithm to enhance image in digital
image processing, an Infrared Image Gray adaptive adjusting Enhancement Algorithm
Based on Gray Redundancy Histogram-dealing Technique is proposed. The algorithm
is based on the determination of the entire image gray value, enhanced or lowered the
image’s overall gray value by increasing appropriate gray points, and then use
gray-level redundancy HE method to compress the gray-scale of the image. The
algorithm can enhance image detail information. Through MATLAB simulation, this
paper compares the algorithm with the histogram equalization method and the
algorithm based on gray redundancy histogram-dealing technique
, and verifies the effectiveness of the algorithm.
