algorithm used to calculate the absolute length of the 2D vector

  • VLT_L2: sqrt(gx*gx+gy*gy)
  • VLT_max: max(fabs(gx), fabs(gy))

template<class InputStorageType, class OutputStorageType>
enum BIAS::FilterBase::TBorderHandling
inherited

enum for border calculation, same meanings as in matlab:

  • TBH_valid: returns only the pixels whose values can be computed without using zero padding of the input image. The resulting output image is smaller than the input image. The ROI of the output image is set accordingly.
  • TBH_same: returns the set of pixels that can be computed by applying the filter to all pixels that are actually part of the input image. Border pixels are computed using zero padding, but the center pixel of the computational kernel is applied only to pixels in the image. This results in an output image that is the same size as the input image.
  • TBH_full: returns the full convolution. This means conv2 returns all pixels for which any of the pixels in the computational molecule overlap pixels in the image, even when the center pixel is outside the input image. The resulting output image is larger than the input image. This is not implemented at the moment.

Member Function Documentation

template<class InputStorageType , class OutputStorageType >
void GradientGaussAsymmetric::_CalculateKernels ( double  Sigma,
double  Ratio 
)
protected

Fills _HVec with gaussian function and _VVec with derivative of gaussian function with standard deviation Sigma.

The size of _HVec and _VVec is calculated by using Ration. The Gaussian function is truncated, when the ration between biggest and smalles entry falls below Ratio.

Todo:
check if this is a proper filter mask in the sense of convolution -> reflection at center. We might have introduced an inconsistency here when switching to generic convolution.
