+Depth Modes
+###########
+
+Left-Right Check
+****************
+
+Left-Right Check or LR-Check is used to remove incorrectly calculated disparity pixels due to occlusions at object borders (Left and Right camera views
+are slightly different).
+
+#. Computes disparity by matching in R->L direction
+#. Computes disparity by matching in L->R direction
+#. Combines results from 1 and 2, running on Shave: each pixel d = disparity_LR(x,y) is compared with disparity_RL(x-d,y). If the difference is above a threshold, the pixel at (x,y) in the final disparity map is invalidated.
+
+Extended Disparity
+******************
+
+The :code:`extended disparity` allows detecting closer distance objects for the given baseline. This increases the maximum disparity search from 96 to 191.
+So this cuts the minimum perceivable distance in half, given that the minimum distance is now :code:`focal_length * base_line_dist / 190` instead
+of :code:`focal_length * base_line_dist / 95`.
+
+#. Computes disparity on the original size images (e.g. 1280x720)
+#. Computes disparity on 2x downscaled images (e.g. 640x360)
+#. Combines the two level disparities on Shave, effectively covering a total disparity range of 191 pixels (in relation to the original resolution).
+
+Subpixel Disparity
+******************
+
+Subpixel improves the precision and is especially useful for long range measurements. It also helps for better estimating surface normals
+
+Besides the integer disparity output, the Stereo engine is programmed to dump to memory the cost volume, that is 96 levels (disparities) per pixel,
+then software interpolation is done on Shave, resulting a final disparity with 5 fractional bits, resulting in significantly more granular depth
+steps (32 additional steps between the integer-pixel depth steps), and also theoretically, longer-distance depth viewing - as the maximum depth
+is no longer limited by a feature being a full integer pixel-step apart, but rather 1/32 of a pixel.
