Object Detection and Neural Networks

This tech talk covers performing object detection using convolutional neural networks (CNNs) in ERDAS IMAGINE. The process is divided into three stages: capturing training data, training the neural network, and applying the trained model to new images. The tutorial demonstrates how to use machine learning layout tools to capture training footprints and image chips, create training samples, and train a CNN. Finally, it shows how to apply the trained model to detect objects in new aerial photos, specifically mapping oil palm locations.
