Webfrequencies of a Gabor filter. Because Gabor filters are geometrically composed using a combination of sinusoids with varying frequencies, they are conventionally used to extract not only mid-frequency features but also very high frequency components such as the fine wrinkles present on a palm print [33] and iris muscle patterns for iris ... In document image processing, Gabor features are ideal for identifying the script of a word in a multilingual document. Gabor filters with different frequencies and with orientations in different directions have been used to localize and extract text-only regions from complex document images (both gray and colour), since text is rich in high frequency components, whereas pictures are relatively smooth in nature. It has also been applied for facial expression recognition Gabor …
