Known Issues

• When uploading an image with multiple faces in the Face Detection API, not all faces can be detected. Suggest using images with only one face or trim the image to contain one face only before using this API.

• When using the quality check API to detect the optimal rotation angle, some images may return the wrong rotation angle. We are currently working on modifying the algorithm to improve the accuracy.

• If the same image is added and deleted over 5 times in a feature database with max_size larger than 100K, the cross-database search (1vN) API has the possibility to get an empty set, even if there are similar features registered. To prevent this issue, create a feature database with a smaller size or avoid adding and deleting the same image multiple times.
