Web11.3.4.2 Gabor filter features. The Gabor filter feature extraction process starts with the application of a two-dimensional Gabor filter which is applied to each image individually. The process is guided by Gabor's uncertainty principle, which states that the product of frequency resolutions and time must be greater than a constant. WebGaborFilter is a linear, spatially directional and frequency-selective filter commonly used in image processing for texture analysis and segmentation. In the spatial domain, a 2D …
WebLike the Gabor filter, the log-Gabor filter has seen great popularity in image processing. Because of this it is useful to consider the 2-dimensional extension of the log-Gabor filter. With this added dimension the filter is not only designed for a particular frequency, but also is designed for a particular orientation.
