+Temporal Auto-Exposure with Hardware Blending
+=============================================
+
+Some graphics pipelines compute auto-exposure like this:
+   :Textures:
+      #. Previous average brightness
+      #. Current average brightness
+   :Passes:
+      #. Store previously generated average brightness
+      #. Generates current average brightness
+      #. Smooth average brightnesses and compute auto-exposure
+
+You can use hardware blending for auto-exposure:
+   :Textures:
+      #. Average brightnesses (previous + current)
+   :Passes:
+      #. Generate and smooth average brightnesses
+      #. Compute auto-exposure

+Census Transform in HLSL
+========================
+
+The census transform is a filter that represents the pixel's neighborhood relationship in a binary string. The binary string will be ``0000000`` if the center pixel is lesser than all of its neighbors. The binary string will be ``11111111`` if the center pixel is greater than or equal to all of its neighbors.
+
+The filter does not depend on the image's actual intensity. As a result, the filter is robust to illumination.
