Method for reducing communication data amount in business to business electronic commerce

A method of detecting local features of video which includes the steps of: extracting a first static image and a second static image from a video made up of a plurality of static images; calculating a feature quantity of the first static image and a feature quantity of the second static image; detecting the second static image having a feature quantity such that a difference in feature quantity between the first static image and the second static image satisfies a predetermined condition; and displaying the second static image thus detected and the feature quantity difference in one-to-one correspondence.

Method and apparatus for detecting local features of video, and recording medium storing the method

When an image input button, an image to be edited is acquired and selected pieces of picture data representing the acquired image is displayed. With an order to play back pieces of image data corresponding to the selected pieces of picture data, a play back order is specified by display indicators. When an image output button is pressed, pieces of image data corresponding to the selected pieces of picture data are played back in the specified play back order.

Image-display edit processing method, image editing apparatus and storage medium

The video retrieving method provides a video retrieval man-machine interface which visually specifies a desired video out of many stored videos by using previously linked picture data corresponding to the videos. Also, a video reproduction operating man-machine interface visually designates the position of reproduction out of the picture group indicative of the contents. The video retrieving method employs video data, character information linked to the video data, picture data linked to the videos, and time information corresponding to the picture data in the video data. The character information is composed of a title of each video and a creation date thereof. The picture data include, as retrieval information, one picture data representing the content of the relevant video (one picture expressing the video, i.e., a leaflet or the like), and a plurality of picture data adapted to grasp the contents of the entire video. The time information indicates the temporal position of the picture data in the video data.
