Abstract
A contrast-based image fusion system and method of processing multiple images to form a processed or fused image including regions selected from one or more images. Images are divided into image regions. Portions of the images are filtered if necessary. A contrast map is generated for each image via a convolution kernel resulting in a contrast map with contrast values for each image region. Contrast values are compared and image regions are selected based on a selection criteria or process such as greater or maximum contrast. The selected image regions form the fused image. If necessary, the luminance of one or more portions of the fused image is adjusted. One sensor is selected as a reference sensor, and an average intensity of each region of the reference sensor image is determined across the reference sensor image. The intensity of one or more regions in the final image is adjusted by combining the determined average luminance values and intensity values of the final image.
