Image processing and the analysis of images in order to extract relevant data is an ever-growing topic of research. Although there are numerous methods readily available, the task of image preprocessing and feature extraction requires developing specific algorithms for specific problems by combining different functions and tweaking their parameters. This paper proposes a framework that allows.

Feature extraction by using gabor filter 1 view (last 30 days) Gregor on 12 Sep 2012 0 Link Hello, I'm quite new in the field of SVM's and would need an advice. I currently trying to optimize a SVM (based on LIBSVM). I was thinking about using a gabor filter to extract the features from my images. Gabor filters are bandpass filters which are used in image processing for feature extraction, texture analysis [1] , and stereo disparity estimation [9,10,13-15,24,30] . The impulse response of these filters is created by multiplying an Gaussian envelope function with a complex oscillation. Gabor [11] showed that these elementary functions.

Reshape data into a matrix X of the form expected by the kmeans function. Each pixel in the image grid is a separate datapoint, and each plane in the variable featureSet is a separate feature. In this example, there is a separate feature for each filter in the Gabor filter bank, plus two additional features from the spatial information that was added in the previous step.

Gabor wavelet transform is applied to extract feature. Affected by illumination, gesture, expression and other factor's variation, face image pattern is easy to be changed, so it is important to find a robust data representation for the correct classification of face pattern.
