The document describes a study on detecting kidney stones using image processing and deep learning techniques. The researchers preprocessed CT and MRI scan images of kidney stones using techniques like gray level co-occurrence matrix for feature extraction. They then trained a convolutional neural network (CNN) model on the images to classify kidney stones. The CNN model consisted of convolution, ReLU, pooling and fully connected layers. The trained model could accurately detect and classify kidney stones in input images. The researchers concluded that combining image processing and deep learning was an effective method for automated kidney stone detection.
