Is computer vision a subset of machine learning?

Computer vision is not strictly a subset of machine learning, but the two are closely intertwined. Computer vision focuses on enabling machines to interpret and process visual data, such as images and videos, while machine learning provides algorithms and models to learn patterns from data and make predictions. Many computer vision techniques, particularly in recent years, rely on machine learning models, such as convolutional neural networks (CNNs) or transformers. However, computer vision also involves traditional image processing methods that do not require machine learning. Techniques like edge detection, histogram equalization, and morphological operations fall under this category. These approaches are valuable for tasks where machine learning may not be necessary or feasible. While modern computer vision heavily incorporates machine learning, the field itself is broader and includes elements of signal processing, computer graphics, and even physics. It is more accurate to say that machine learning has become a critical enabler for advancements in computer vision rather than labeling computer vision as a strict subset.
