Is it legal to use face detector (such as MTCNN) to detect the face?
I notice that there are more than one face in some of the images, are there any method to deal with these images?
Dear yjhuang,
thanks for pointing this out. In fact, there may be a very small number of images where you will find multiple faces. As a rule of thumb, the main face will be always roughly in the middle of the image, whereas secondary ones may be found on the background. Regarding your question, any free-of-use public non-commercial software can be used.
Best Regards
Is it legal to manually label face boxes？
Dear participant,
you can label your train data as we didn't impose any restriction on this.
However, you may need to consider that at the code verification stage, we are going check the results of winning approaches on the test set without any extra labels.
Best
