Abstract
A method for valuation of image dark data based on similarity hashing, the method including: (1) acquiring a dark dataset, and inputting the dark dataset into a trained deep self-taught hashing algorithm model to obtain a hash code of each image in the dark dataset; (2) constructing a hash map according to the hash code of each image in the dark dataset obtained in (1), where the hash map includes a plurality of nodes, each node represents the hash code of each image; (3) acquiring a significance score of each node in the hash map obtained in (2); and (4) sorting significance scores of the plurality of nodes obtained in (3) in a descending order, and outputting images corresponding to top k significance scores of the plurality of nodes to users, where k is a natural number.
