摘要:
A system and method for reflection removal of an image from a dual-pixel sensor. The image including a left view and a right view. The method including: determining a first gradient of the left view and a second gradient of the right view; determining disparity between the first gradient and the second gradient using a sum of squared differences (SSD); determining a confidence value at each pixel using the SSD; determining a weighted gradient map using the confidence values; minimizing a cost function to estimate the background layer, the cost function including the weighted gradient map, wherein the image includes the background layer added to a reflection layer; and outputting at least one of the background layer and the reflection layer.
