static void  LocalEigenValuesAndVectors (ImagePlane plane, FixedFilterSize derivatorSize, FixedFilterSize blurSize, out Image lambda1, out Image lambda2, out Image eigenValue1x, out Image eigenValue1y, out Image eigenValue2x, out Image eigenValue2y) 
Calculate the local eigenvalues and eigenvectors of the Hesse matrix applied to the pixels of the input image. More...  
static Image  LocalMinEigenValues (ImagePlane plane, FixedFilterSize derivatorSize, FixedFilterSize blurSize) 
Calculate the minimum local eigenvalues of the Hesse matrix applied to the pixels of the input image. This approach helps identify locations inside the image that contain curved edges. More...  
static double  WangQuality (ImagePlane plane1, ImagePlane plane2) 
Calculate the Wang quality for two images. The Wang Quality is a measure of similarity between two images as proposed in a publication by Z. Wang and A. C. Bovik (IEEE Signal Processing Letters, vol. 9, no. 3, pp. 8184, March 2002). More...
