Function Documentation

bool puma::compute_orientationST(Workspace *grayWS, double dogsigmaArr, double gausigmaArr, puma::Cutoff cutoff, puma::MatVec3<double> *direction, bool print = true, int numThreads = 0)

Function to compute the orientation using the Structure Tensor (i.e. find the direction of least gradient change)

Parameters

• grayWS – the input workspace to serve as a mask according to the cutoff (Note: the ST filter is applied on the whole image, the cutoffs are only applied when computing the Eigenvectors to put in the direction MatVec3)

• dogsigmaArr – kernel size parameter for Gaussian derivatives (should be smaller than rho)

• gausigmaArr – kernel size parameter for Gaussian filter (should be bigger than sigma)

• cutoff – the grayscale range to consider, according to the input ws

• direction – the output orientation field

• print – whether to print progress, optional

• numThreads – number of threads to use, optional

Returns

true if successful, false if it failing
