Deep Learning Soil Classification

The video tutorial covers soil classification using a convolutional neural network (CNN). It begins with an introduction to different soil types and their classification criteria. The setup of the Python environment, including necessary modules and directories, is explained. Data processing and augmentation techniques are discussed to prepare images for training. The tutorial then details the construction and training of a CNN model using TensorFlow. Testing and potential improvements to the model are explored, followed by a look at alternative classification methods like texture classification.
