METHOD FOR ENCODING EMOTION INFORMATION ON MEDIA FILE, METHOD FOR DECODING ENCODED EMOTION INFORMATION FROM ENCODED MEDIA FILE, SEARCHING METHOD FOR MEDIA FILE ENCODED EMOTION INFORMATION AND PROGRAM RECORDING MEDIUM THEREOF

摘要

The present invention relates to a method for quantitatively encoding and decoding emotion information in media information such as an image or sound. More specifically, in the encoding method, the emotion information is added to the media file by adding the emotion information to the media file to binarize the emotion information and compare it with the least significant bit of each data value of the media file. It is to quantitatively encode emotion information by creating modified media files to be compatible. In the decoding method, the modified media file is loaded to separate media data, extract emotion information header data, and acquire emotion information data therefrom and decode emotion information in a manner of determining emotion information in association with a predetermined emotion database. The encoding and decoding method may include a situation in which the emotion of the robot is encoded in association with the media, and also emotion information may be extracted without additional external information through the encoded media file according to the present invention.;Emotion Information, Data Encoding, Data Decoding, Robot Emotion Encoding, Image Files, Sound Files
