A method of providing search results based on multi-modal features includes performing a vector operation between attributes according to a user query on a multi-modal embedding space; and providing search results corresponding to the user query based on an embedding vector acquired through the vector operation.

Method, computer device, and non-transitory computer-readable recording medium to provide search results based on multi-modal features

A method for extracting a fingerprint of a video having a plurality of frames includes obtaining a plurality of pixel value matrices from each of the plurality of frames, calculating maximum values of average pixel values in each axis of the plurality of pixel value matrices for each of the plurality of frames, and calculating the fingerprint of the video based on a temporal correlation of the maximum values calculated for the plurality of frames.

Method and apparatus for extracting a fingerprint of video having a plurality of frames

A method for extracting a fingerprint of a video includes calculating 2D discrete cosine transform (DCT) coefficients from each of the plurality of frames of the video, extracting, from the 2D DCT coefficients, a coefficient having a basis satisfying at least one of up-down symmetry or left-right symmetry, and calculating a fingerprint of the video based on the extracted coefficient.
