Embodiment Construction
[0095] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0096] In the prior art, the semi-coupling mapping strategy is not used to connect the relationship between sketch images and ordinary photos to reduce the differences between heterogeneous samples. Intrinsic projections of heterogeneous data can be revealed without combining learned metric matrices. For sketch images and ordinary photos in complex scenes, the prior art dictionaries do not have good applicability. The existing technology does not combine discriminant constraints to make the same category compact and separate different categories, which is not conducive to retrieval and classification.
