In this paper, a method to extract temperature effect information using the color temperatures of video scenes with mapping to temperature effects is proposed to author temperature effects of multiple sensorial media content automatically. An authoring tool to apply the proposed method is also introduced. The temperature effects generated by the proposed method are evaluated by a subjective test to measure the level of satisfaction. The mean opinion score results show that most of the test video sequences receive an average of approximately four points (in a five-point scale), indicating that test video sequences (with the temperature effects generated by the proposed method) enhance levels of satisfaction.Keywords: Sensory effects, MPEG-V, MulSeMedia content, MulSeMedia authoring, sensorial information extraction, sensorial information mapping, temperature effect.

I. IntroductionAlong with the sensation of the 3D film industry, the development of MulSeMedia (Multiple Sensorial Media) [1] or 4D media has received a lot of attention from the public. 4D movies generally add sensory effects to 3D and/or IMAX movies, allowing audiences to immerse themselves more deeply into the movie viewing experience. Along with the two human senses of sight and hearing, such sensory effects as wind, vibration, and scent can stimulate other senses, such as the tactile and olfactory senses. MulSeMedia content indicates audiovisual content annotated with sensory effect metadata.Since 2008, the MPEG International Standardization Group has been working to define interfaces and data formats between the virtual and real worlds, under the project name MPEG-V (ISO/IEC 23005) [2]-[5]. This standard supports the interoperability of data formats between sensory effects authored by content providers, rendering effects of diverse consumer and professional devices, and rendering environments. Due to the standardized format specified by MPEG-V, content providers can convey sensory effects as precisely as intended to consumers.MulSeMedia content contains the metadata of sensory effects that are derived from physical properties of scenes, such as those containing wind, light, temperature, color, motion, and sound effects, as well as the emotional properties of the content. The emotional properties of the content include such feelings as happiness, love, fear, anger, surprise, or hatred. If emotions and feelings were to be expressed as appropriate sensory effects, viewers would be able to immerse themselves more deeply in the content as opposed to simply experiencing the sensory effects of the physical properties in the scenes. Experiences of such sensory effects can also assist with the For the successful industrial deployment of MulSeMedia services, it is important to provide an easy and efficient means of producing MulSeMedia content. The existing methods of producing MulSeMedia content incur much time and effort to author sensory effects. Sensory effect author...
