Deep Binary Representation for Efficient Image Retrieval

Table 4

MAP of image retrieval on CIFAR-10 dataset with 4 different bit lengths. We use 1000 query images and calculate the MAP within top 5000 returned neighbors. The first line is the result of semantically even situation and the second is semantically uneven situation.

Method	CIFAR-10 (MAP)
	16 bits	24 bits	32 bits	48 bits
DBR-even	0.612	0.648	0.658	0.680
DBR-uneven	0.608	0.647	0.658	0.683
