Pointing at the difficulty in the edge detection of infrared image

the characteristics of the infrared image and its gradient image are analyzed

a daptive edge detecting algorithm based on Tsallis entropy of infrared image is proposed. This method computes the Tsallis entropy of edge and non-edge of 1ocal-image differently.based on the best Tsallis entropy of local image

a evaluation function is proposed.Based on the evaluation

the different structure of edge detecting is selected

the image edge information is enhanced

and avoids the edge missing.Experiment results show that

compared with the traditional edge detecting method

this method decreases the noise of infrared image as possible as it can and enhances image edge.
