The article discusses the process of converting and scaling PIL Images to Images in PyTorch using functions like Compose() and ToImage(). It explains how ToTensor() can be used to convert a PIL Image or ndarray to a tensor and scale the values accordingly. The author recommends using the newer version (v2) of the functions for better compatibility and performance. Various examples and code snippets are provided to demonstrate the usage of these functions with different data types such as int, float, complex, and bool.
