WebFirst, we used residual neural networks for automatic feature extraction. Then, we proposed a second network consisting of Gabor kernels to extract another set of features from the IC-NST dataset. After that, we performed a late fusion of the two sets of features and passed the output through a custom classifier.
WebGabor filters are designed to resemble the performance of the mammalian visual cortical cells, in a sense of extracting features at different orientations and scales. This multiresolution sensitivity of Gabor filters may be helpful for extracting useful meaningful features that can characterise underlying physiology.

Then, the most discriminate features are selected based on mutual information criteria. The system can automatically recognize six expressions:anger, disgust, fear, happiness, sadness and surprise.
There are several ways to extract features with Gabor filters. The most relevant ones are discussed below: 1. The simplest way to generate features with Gabor Filters is to use the real or the imaginary part of the response matrix as a feature vector 2. The phase of the response matrix can be taken as a feature vector … See more In this tutorial, we’ll talk about the Gabor filters, a classic tool in image processing. First, we’ll explain how to compute them. Then we’ll illustrate how to generate featuresfor machine learning using Gabor filters. See more A Gabor filter is a linear filter used in image processing for edge detection, texture classification, feature extraction and disparity estimation. It is a bandpass filter, i.e. it passes frequencies in a certain band and attenuates … See more In this article, we reviewed the Gabor convolution filters, commonly used in image processing. Finally, we illustrated how to extract features from images using Gabor filters. See more
