LDR-HDR cost calculation comparison. a, b Left and right views; c, d LDR and HDR computed disparity maps; e, f zoomed areas from c and d; (g 1), (g 2), (g 3), and (g 4): from top to bottom: cost values, color/radiance-differences, and gradient-differences between pixels x 1, \(x^{\prime }_{1}\), x 2, and \(x^{\prime }_{2}\), and the pixel shifted by different disparity levels (1–150 pixels) in the x direction of the same line. (g 2) and (g 4) show how by working in HDR space we achieved a more pronounced minimum among costs
