WebOct 1, 2024 · The gabor_feature_extraction method extracts the Gabor Features of the image. This method is modified in comparison to the initial Matlab code to give users the option to downsample the image or to normalize the features. Moreover, I added the Magnitude feature because according to literature it improves predictability. WebTexture feature description is a remarkable challenge in the fields of computer vision and pattern recognition. Since the traditional texture feature description method, the local binary pattern (LBP), is unable to acquire more detailed direction information and always sensitive to noise, we propose a novel method based on generalized Gabor direction pattern …
