Abstract: Local detail enhancement (LDE) is an imagery contrast enhancement method applied to visible and uncooled long wave imagery. It enhances local spatial detail through the use of a median based high/band pass filter. The generated detail channel is blended with a histogram-equalized version of the image, creating an image that contains both local detail as well as retaining some amount of global intensity. Retaining global intensity coherency allows for easier target acquisition when compared to fully local forms of contrast enhancement.

Abstract: Systems and methods of image enhancement comprising: obtaining image data; analyzing the image data and gathering relevant statistics thereon, at least within a first region of interest and a second region of interest; using the gathered statistics corresponding to the first region of interest, configuring a first contrast enhancement module to perform contrast enhancement of at least a first portion of the image data; using the gathered statistics corresponding to the second region of interest, configuring a second contrast enhancement module to perform contrast enhancement of at least a second portion of the image data; and combining the contrast-enhanced image data to form a complete image
