How to detect infrared dim targets accurately under complex background and low SCR
condition is of great significance for the development of precision guided weapons and
infrared warning. In order to improve the SCR and detect the dim targets effectively, a new
method for infrared dim target detection based on the gray contrast between the central
region and its neighborhood was proposed. The contrast of the target was improved by
calculating the contrast map and saliency map of the input image while suppressing the …
