Anti-Aliasing Node.

The Anti-Aliasing node removes distortion artifacts around edges known as aliasing.

Tính Chất (Properties)

Ngưỡng (Threshold)

Controls edge detection sensitivity across the whole image.

Giới Hạn Tương Phản (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.

Làm Tròn Góc (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.

../../../_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.

../../../_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.
