Face recognition models need precise landmark alignment for accuracy

Face recognition models require precise alignment to maintain accuracy, as deviations in rotation or scale can lead to misidentification. This process involves detecting key facial landmarks, such as the eyes, nose, and mouth corners, to transform the detected face into a canonical pose. Different detection pipelines, like MTCNN and RetinaFace, output these landmarks, which are then used to compute a similarity transform to align the face to a standard template, ensuring consistent embeddings for recognition.
