Nút Khử Răng Cưa (Anti-Aliasing Node)#

Nút Khử Răng Cưa.

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

Đầu Vào (Inputs)#

Đầu vào màu tiêu chuẩn.

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 option 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.

Corner detection and rounding off (set to 0). Notice how corners are smoothed because they are treated as artifacts.#

Full corner detection and rounding preserves the sharp edges around the corner.#
