+
+   Anti-Aliasing Node.
+
+The Anti-Aliasing node removes distortion artifacts around edges known as aliasing.
+
+
+Inputs
+======
+
+Image
+   Standard image input.
+
+
+Properties
+==========
+
+Threshold
+   Controls edge detection sensitivity across the whole image.
+
+Contrast Limit
+   Controls contrast level to consider when detecting edges.
+
+   The human eye does not perceive all edges equally. For instance,
+   it tends to mask low contrast edges in the presence of much higher contrasts in the surrounding area.
+   Therefore, applying anti-aliasing to unperceived edges will produce artifacts.
+   This parameter quantifies the difference between low contrast and high contrast neighboring edges.
+
+Corner Rounding
+   Detect corners to help preserve the original shape.
+   Setting *Corner Rounding* to 0 means no corner detection and no corner rounding will take place.
+   The higher the value the better corners will be preserved, i.e. resemble original image.
+
+
+Outputs
+=======
+
+Image
+   Standard image output.
+
+
+Examples
+========
+
+.. list-table:: The Anti-Aliasing node has three properties shown here.
+
+   * - .. figure:: /images/compositing_types_filter_antialiasing-node_example-1-threshold.gif
+          :align: center
+
+          Changing threshold affects all edges.
+
+     - .. figure:: /images/compositing_types_filter_antialiasing-node_example-2-contrast_limit.gif
+          :align: center
+
+          Changing contrast limit affects neighboring edges below contrast limit.
+
+.. list-table:: The effect of corner rounding.
+
+   * - .. figure:: /images/compositing_types_filter_antialiasing-node_example-3-corner_rounding-off.png
+
+         Corner detection and rounding off (set to 0).
+         Notice how anti-aliasing node smooths the corner because it treats it as an artifact.
+
+     - .. figure:: /images/compositing_types_filter_antialiasing-node_example-3-corner_rounding-on.png
+
+         Corner detection and rounding on.
+         Setting this value to 1 tells the anti-aliasing node the sharp edges
+         around the corner are not an artifact and should therefore be reserved.
