Abstract
In an example embodiment, method, apparatus and computer program product are provided. The method includes facilitating receipt of first image (I1) and second image (I2) of a scene. Cost volume between images I1 and I2 for set of foreground labels (FL) and set of background labels (BL) is determined that includes matching costs of pixels in I1 and corresponding pixels in I2 for FL and BL. Reduced cost volume is determined from the cost volume, including matching costs of pixels in I1 and corresponding pixels in I2 for FL and a background label (L1) of BL, where matching cost of an individual pixel in I1 and corresponding pixel of the individual pixel in I2 for L1 includes minimum matching cost from a set of matching costs of the individual pixel for BL. A disparity map is generated by performing cost aggregation of the reduced cost volume in I1 and I2.
