SIFT (Scale-Invariant Feature Transform) is preferred over CNNs in scenarios requiring handcrafted feature extraction, such as applications with limited computational resources or where interpretability is critical. SIFT is effective for detecting and describing local features in images, making it suitable for tasks like image stitching, 3D reconstruction, or object matching in smaller datasets. Unlike CNNs, which require training on large datasets, SIFT operates directly on the image without needing extensive pre-training. It is particularly useful in applications where simplicity, robustness to scale and rotation, and resource constraints are priorities.
