As I know, there are many algorithms to process face recognition by using recognition points. For twins recognition, we need to increase the number of recognition points, because twins also have some various features. However, this will reduce the algorithm performance. And maybe just a little change on face, the algorithm cannot recognize. If we reduce the number of recognition points, face of twins may be passed over. My question is: How to perform face recognition for twins, but guarantee can recognize human if his face has a little changes (after waking up, getting older, making up etc.)? Or any recommendations!

Anything relating to twin recognition (includes deep learning etc).
Having a big background in face recognition, honestly speaking, I don't think that there is any possibility to distinguish identical twins just based on facial photographs. This is particularly true when you want to be able to recognize them in adverse conditions, e.g., difficult illumination, low resolution and alike.
Just think about how humans would distinguish twins. They would not rely on the facial images, but on other behavioral traits that are not available in the images.
If the information is not inside the images, you cannot extract the information. Hence, there is very little chance that any purely image-based algorithm would be able to distinguish twins.
I think for better performance for identical twins, use multi-Biometrics especially on face and ear images which ear image is a part from profile face image. Moreover, ear images have used to identical twins and triplets.

yes.we can do distinguish between identical twins using facial marks. for more information refer the following articleArticle Analysis of Facial Marks to Distinguish Between Identical Twins
