Video retrieval method and apparatus using vectorized segmented videos based on key frame detection

A non-transitory computer readable storage medium storing a computer program, in which when the computer program is executed in one or more processors, the computer program causes the one or more processors to perform operations for performing a video retrieval method, the video retrieval method comprising:

• segmenting one or more video data into two or more unit video data;
• encoding, by one or more encoders comprised in a machine learning enabled key frame detection module, two or more unit video data;
• generating one or more key frame detection vectors for each of the two or more unit video data based on the encoding result;
• and
• generating feature vector of one or more retrieval video data based on a combination of one or more vectors among the key frame detection vectors.

A computing device performing a video retrieval method, the computing device comprising:

• a processor including at least one core;
• and
• a memory including program codes executable in the processor,
• wherein the processor:
• segments one or more video data into two or more unit video data;
• encodes, by one or more encoders comprised in a machine learning enabled key frame detection module, two or more unit video data;
• generates one or more key frame detection vectors for each of the two or more unit video data based on the encoding result;
• and
• generates feature vector of one or more target retrieval video data based on a combination of one or more vectors among the key frame detection vectors.
