Detection of professional techniques in cooking by image processing

Generally, professional cooks directly teach cooking techniques to apprentices; however, in recent years, it is getting more difficult to deploy this traditional teaching method because the number of both professional cooks and students has been decreasing. Although a recently proposed method that uses archived videos, can be replacement of the traditional one, it is not easy to understand the cooking techniques with only watching the video. Obviously, professional techniques are usually ambiguous and accumulated by their continual daily work. Therefore, this paper proposes a new system that uses thermographic images for detecting ambiguous techniques from the Chinese cooking videos, and it discovers what the differences are between professional and unprofessional cooking from the videos.
