A method includes a step of acquiring a first image of a scene using a first image sensor of an electronic device and acquiring the first image of the scene using a second image sensor of the electronic device. The method also includes a step of generating a first feature map from the first image and generating a second feature map from a second image. The method further includes a step of generating a third feature map based on the first feature map, the second feature map, and an asymmetric search window. The method further includes a step of generating a depth map by restoring spatial resolution for the third feature map.
