Depth channel extraction

The process of isolating spatial distance information from an image to create a grayscale representation where pixel luminance corresponds to the distance from the camera lens.

Applications

  • lens-blur: Simulating realistic bokeh by applying depth-dependent convolution.
  • 3d-photo-adjustments: Executing localized color grading, lighting, and atmospheric effects based on spatial planes.
  • Compositing: Creating seamless integration between foreground and background elements using depth-aware masking.
