Image marking method and electronic equipment

The invention provides an image marking method and electronic equipment, relates to the technical field of image mining, and mainly solves the technical problem of accurate description of an image. The method comprises the steps of obtaining a label set of a to-be-marked image, wherein the label set comprises at least one existing label of the image; filtering the labels in the label set to obtainfiltered labels; calculating a visual similarity matrix and a semantic similarity matrix between the labels according to the filtered labels; calculating a mixed similarity matrix according to the visual similarity matrix and the semantic similarity matrix, and clustering the mixed similarity matrix to obtain a visual theme of the to-be-marked image, the visual theme comprising at least one filtered label; and marking the to-be-marked image by adopting the visual theme. Therefore, extra data does not need to be introduced for training, and the public pre-training algorithm model is fully utilized; the method has the
