Embodiment Construction
[0037] Preferred embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although preferred embodiments of the invention are shown in the drawings, it should be understood that the invention may be embodied in various forms and should not be limited to the embodiments set forth herein.
[0038] A kind of image fusion method based on contrast analysis, it comprises the following steps:
[0039] Step 1: respectively constructing the morphological gradient map of the input image and its enhanced image; (the enhanced image can be: an enhanced image for the target, edge, resolution, contrast, etc.)
[0040] Step 2: Subtract the morphological gradient maps of the input image and its enhanced image to obtain the contrast difference map of the input image before and after enhancement;
[0041] Step 3: Construct a fusion coefficient matrix according to the contrast difference map;
[0042] Step 4: Complete the fusion of...
