Figure 8. CNN-based end-to-end regression for livestock body weight prediction from RGB or RGB-D images, extracting hierarchical features through convolutional blocks and predicting weight via a fully connected regression head. The input image shown in Figure 8 was collected by the authors at Guojia Pig Farm, Longyao County, Xingtai City, Hebei Province, China. CNN: Convolutional neural network; RGB: red-green-blue; RGB-D: red-green-blue-depth; ReLU: rectified linear unit.
