Abstract: In applications of image analysis and computer vision, Gabor filters have maintained their popularity in feature extraction. The reason behind this is that the resemblance between Gabor filter and receptive field of simple cells in visual cortex. Being successful in applications like face detection, iris recognition, fingerprint matching; where, Gabor feature based processes are amongst the best performers. The Gabor features can be derived by applying signal processing techniques both in time and frequency domain In this paper basically we did the comparative study about the previous existing approach of Gabor filter and their applications.
Keywords: Gabor filter, Gabor energy, image quality assessment, Gabor features.
