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. 81-84, March 2002). More... | |
