Discriminative Codebook Hashing for Supervised Video Retrieval

Algorithm 1

Discriminative codebook.

Input: the number of categories ; the number of samples per category ; code length ; maximum number of iterations ; fault tolerance rate .
Output: codebook
(1)	for iteration
(2)	for category
(3)	[random half coordinate]
(4)	[the rest coordinate]
(5)	end
(6)	if any two rows of satisfy equation (7)
(7)	break
(8)	end
(9)	end
