Shape-indifferent stereo disparity based on disparity gradient estimation

作者：

Highlights：

• An efficient estimation of disparity gradient for accurate disparities is proposed.

• A 3D cost aggregation within a DSI is performed based on the gradient.

• For any shape, including slanted surfaces, accurate disparities are extracted.
