Glossary: CWT continuous wavelet transform DoG difference of Gaussians DWT discrete wavelet transform LoG Laplacian of Gaussian Haar wavelets Haar wavelet family of wavelets constructed from rescaled square-shaped functions steerable filters steerable filter class of orientation-selective convolution kernels used for feature extraction that can be expressed via a linear combination of a small set of rotated versions of themselves. As an example, the oriented first derivative of a two-dimensional [2D] Gaussian is a steerable filter. | Limiting references: Multi-scale boundary representations
