Expand description

Applies Ridge Detection Filter to an input image. Implements Ridge detection similar to the one in Mathematica using the eigen values from the Hessian Matrix of the input image using Sobel Derivatives. Additional refinement can be done using Skeletonization and Binarization. Adapted from segleafvein and M_RF

Required Methods§

source

fn as_raw_mut_RidgeDetectionFilter(&mut self) -> *mut c_void

Provided Methods§

source

fn get_ridge_filtered_image( &mut self, _img: &dyn ToInputArray, out: &mut dyn ToOutputArray ) -> Result<()>

Apply Ridge detection filter on input image.

Parameters
  • _img: InputArray as supported by Sobel. img can be 1-Channel or 3-Channels.
  • out: OutputAray of structure as RidgeDetectionFilter::ddepth. Output image with ridges.
