Description

DeepFace currently supports cosine distance, Euclidean distance, and Euclidean L2 distance for face embedding comparisons. To enhance distance metric options, we should add angular distance, which is based on the angle between two embeddings. This metric is particularly useful for spherical embeddings and provides an alternative to cosine distance.

Formula

angular_distance = np.arccos(similarity) / math.pi
