Image Local Entropy Algorithm Based on Skewness

Because it is hard to detect infrared weak small targets,put forward a new method of the local entropy algorithm based on skewness.Chunked processing based on the original image,by using local entropy value judgment image block to find interested area,reuse skewness to judgment,through the adaptive threshold segmentation method for small target detection.After the experiment proved that this method can effectively detect the weak target,it has a simple algorithm,the computational complexity is small,convenient for hardware implementation,etc.
