SCENE VARIATION POINT MODEL LEARNING DEVICE, SCENE VARIATION POINT DETECTION DEVICE AND PROGRAMS THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a scene variation point detection device for detecting a scene variation point from a video content.;SOLUTION: A scene variation point detection device 1 includes: image analysis model storage means 10 for extracting an image feature amount of each frame in a video content to preliminarily store an image analysis model for analyzing a subject object in the frame; image analysis means 11 for inputting a variation point known video picture in a learning step of a scene variation point model, and a variation point unknown video picture in a detection step of a scene variation point time sequentially, respectively and extracting the image feature amount of each frame by using the image analysis model; variation point detection means 12 for detecting a scene variation point from an image feature amount of each frame extracted by the image analysis means 11 by using the scene variation point model; and model update means 13 for updating a parameter of the scene variation point model in the learning step.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2018,JPO&INPIT
