It also create a CSV file which has the image name and its corresponding label. * preprocess/greyscale.py processes the images form raw_images, converts them to greyscale, and stores them to greyscale_images. It retains the name of the image. * preprocess/gabor_horizontal.py processes the images form raw_images with gabor filter in the horizontal direction and stores them to gabor_horizontal_images. It retains the name of the image. * preprocess/gabor_vertical.py processes the images form raw_images with gabor filter in the vertical direction and stores them to gabor_vertical_images. It retains the name of the image. * preprocess/laplacian.py processes the images form raw_images with laplacian filter and stores them to laplacian_images. It retains the name of the image. * preprocess/sobelx.py processes the images form raw_images with sobelx filter and stores them to sobelx_images. It retains the name of the image. * preprocess/sobely.py processes the images form raw_images with sobely filter and stores them to sobely_images. It retains the name of the image. * preprocess/sobelxy.py processes the images form raw_images with sobelxy filter and stores them to sobelxy_images. It retains the name of the image. * preprocess/canny.py processes the images form raw_images with canny edge detection and stores them to canny_images. It retains the name of the image. * baseline/raw/network.py contains the custom neural network used for training on raw_images. * baseline/raw/train_and_test.py contains code used for training and testing the neural network on raw_images. * baseline/greyscale/network.py contains the custom neural network used for training on greyscale_images. * baseline/greyscale/train_and_test.py contains code used for training and testing the neural network on greyscale_images. * baseline/gabor_horizontal/network.py contains the custom neural network used for training on gabor_horizontal_images. * baseline/gabor_horizontal/train_and_test.py contains code used for training and testing the neural network on gabor_horizontal_images. * baseline/gabor_vertical/network.py contains the custom neural network used for training on gabor_vertical_images. * baseline/gabor_vertical/train_and_test.py contains code used for training and testing the neural network on gabor_vertical_images. * baseline/laplacian/network.py contains the custom neural network used for training on laplacian_images. * baseline/laplacian/train_and_test.py contains code used for training and testing the neural network on laplacian_images. * baseline/sobelx/network.py contains the custom neural network used for training on sobelx_images. * baseline/sobelx/train_and_test.py contains code used for training and testing the neural network on sobelx_images. * baseline/sobely/network.py contains the custom neural network used for training on sobely_images. * baseline/sobely/train_and_test.py contains code used for training and testing the neural network on sobely_images. * baseline/sobelxy/network.py contains the custom neural network used for training on sobelxy_images. * baseline/sobelxy/train_and_test.py contains code used for training and testing the neural network on sobelxy_images. * baseline/canny/network.py contains the custom neural network used for training on canny_images. * baseline/canny/train_and_test.py contains code used for training and testing the neural network on canny_images. * combined/network.py contains the custom neural network used for training on images with 7 channels [gabor_horizontal, gabor_vertical, laplacian, sobelx, sobely, sobelxy, canny]. * combined/train_and_test.py contains code used for training and testing the neural network on images with 7 channels [gabor_horizontal, gabor_vertical, laplacian, sobelx, sobely, sobelxy, canny].

You will have to rename them to "Net.pt" before you can use them. Drive link: https://drive.google.com/drive/folders/1qC7GQWoFp9Oko-U06pLPvbeLfC_SF34q?usp=sharing
