Abstract
This disclosure is directed to image fusion. A computer system obtains a near infrared (NIR) image and an RGB image of a scene. A first NIR image layer is generated from the NIR image. A first RGB image layer and a second RGB image layer are generated from the RGB image. The first NIR image layer and first RGB image layer have a first resolution. A depth map is also generated and has the first resolution. Each pixel of the first NIR image layer and a corresponding pixel of the first RGB image layer are combined based on a respective weight to generate a first combined image layer used to reconstruct a fused image. For each pair of pixels of the first NIR and RGB layers, the respective weight is determined based on a depth value of a respective pixel of the depth map and a predefined cutoff depth.
