Performs edge-preserving bilateral filtering on an image.

Algorithm: Bilateral filtering as described in Tomasi & Manduchi, "Bilateral Filtering for Gray and Color Images", ICCV 1998. The underlying implementation is in the internal function __bilateral__.

Inputs:

• I: Input grayscale or RGB image (uint8, int8, uint16, int16, uint32, int32, single, or double).
• degree_of_smoothing: Range Gaussian variance (default: 0.01 * dynamic range squared).
• spatial_sigma: Spatial Gaussian standard deviation (default: 1).

Note that for the range Gaussian, the variance is given, and for spatial Gaussian, standard deviation is given.

Name-Value Pair Arguments:

• "NeighborhoodSize": Window size (odd scalar). Default: 2 * ceil (2 * spatial_sigma) + 1.
• "Padding": Border handling. Options:
  • "replicate" (default)
  • "symmetric"
  • "circular"
  • constant scalar value

Output:

• J: Filtered image, same size and class as I.
