摘要:
It is an object of the present invention to detect an image correction method from corrected images, in order to grasp a correction method of a correctly corrected images as a guideline for correction of a harmful image, and to present an image correction proposal to which a correction method in the past is applied, in order to indicate to a corrector a guideline for correction of the harmful image. In order to achieve the above-described objective, the present invention employs the following configuration. With respect to a harmful image data before correction and an image data after correction, a scene feature quantity representing the feature quantity of a scene for each scene of a video is calculated, and by comparing chronological lists of the respective scene feature quantities of the videos, a correction method for the scene configuration is detected.
摘要:
The user terminal 110 executes a search condition input tool 111 according to sample video data stored therein beforehand to create a first media feature value 121 (correct feature value) to be assumed as a reference for searching for a media recognition site. The media recognition server 150 recognizes the sample video 119 and transmits a second media feature value that is a result of the recognition to the user terminal. The user terminal 110 then compares the correct feature value created beforehand with the second media feature value that is a result of the recognition executed at the media recognition server to select a media recognition site that executes the recognition processing according to a user's request.
