Summary:Techniques for generating an enhanced image. A first image is generated using a camera of a first modality, and a second image is generated using a camera of a second modality. Pixels that are common between the two images are identified. An alpha map is generated. The alpha map reflects edge detection weights that are computed for the common pixels based on saliency values. A determination is made as to how much texture from the images to use to generate an enhanced image. This determination is based on the edge detection weights included within the alpha map. Based on the edge detection weights, textures are merged from the common pixels to generate the enhanced image. Color is also added to the enhanced image, where the color reflects an additional property (e.g., the texture source for the pixel) that is associated with one or both of the images.
