More Adaptive and Updatable: An Online Sparse Learning Method for Face Recognition

Algorithm 2

Gallery set update strategy.

	Initialization:
(1)	Obtain gallery set , testing set , and its label .
(2)	Set the initial value for (the maximal number of the pictures of each person in the gallery set).
	Update gallery set:
(3)	In gallery set , find the class that the testing sample belongs to using .
(4)	Obtain the number of the pictures in this class and suppose it is .
(5)	If , remove the picture in the second place from the class and put in the last place. If , put in the last place directly.
