Method: Magick::Image#adaptive_sharpen

Defined in:
ext/RMagick/rmimage.cpp

#adaptive_sharpen(radius = 0.0, sigma = 1.0) ⇒ Magick::Image

Adaptively sharpens the image by sharpening more intensely near image edges and less intensely far from edges.

The #adaptive_sharpen method sharpens the image with a Gaussian operator of the given radius and standard deviation (sigma).

For reasonable results, radius should be larger than sigma. Use a radius of 0 and adaptive_sharpen selects a suitable radius for you.

Returns a new image.

Parameters:

  • radius (Numeric) (defaults to: 0.0) —

    The radius of the Gaussian in pixels, not counting the center pixel.

  • sigma (Numeric) (defaults to: 1.0) —

    The standard deviation of the Laplacian, in pixels.

Returns:
