Embodiment Construction
[0060] The precision enhancement method for visual media semantic index proposed by the present invention comprises the following steps:
[0061] (1) Perform semantic indexing on the objects and scenes contained in the initial visual media to obtain the detection confidence value of the initial visual media semantic index, and construct a matrix C according to the detection confidence value, and the rows in the matrix C correspond to A sample in video media c i , 1≤i≤N, such as an image or a video shot, the column in the matrix C corresponds to an object or scene v j , 1≤j≤M, any element c in the matrix C ij Indicates sample c i the contained object or scene v j The detection confidence value, wherein, N represents the number of samples, and M represents the number of objects or scenes;
[0062] (2) Set a detection confidence threshold, compare the detection confidence value in the above matrix C with the set detection confidence threshold, if the detection confidence valu...
