Cross-Modal Discrimination Hashing Retrieval Using Variable Length

Algorithm 2

Testing produce of the proposed method.

	Input: Testing datasets ; trained , and .
	Output: The top n cross-modal data matching the samples to be retrieved.
	Procedure:
(1)	if input independent or then
(2)	compute the corresponding hash code by or ;
(3)	end if
(4)	if input paired then:
(5)	if hash code exists in space of Y data:
	;
(6)	else:
	;
(7)	end if
(8)	end if
(9)	Calculate the Hamming distance between the hash code b' and the hash codes of all samples in the retrieval database
(10)	Sort the distances calculated in ascending order, and return the first n samples.
