MPEG-7 based Color Temperature Customization
نویسندگان
چکیده
MPEG-7 is a new standard which addresses the multimedia content description problem at very different levels: description tools range from low-level features such as color and pitch to high-level features such as the name of the characters in a scene or the title of a movie. This paper presents an MPEG-7 enabled application based on a low-level descriptor: the visual color temperature. The implemented application relates the human perception of color with low-level information, automatically extractable, thus allowing to customize the visual content according to the user color temperature preferences.

This paper conducts an empirical evaluation of MPEG-7 visual part of experimentation model (XM) color descrip-tors in a challenging problem of content-based retrieval of semantic image categories. The performance of the four color descriptors provided in the current XM reference implementation, Color Layout, Color Structure, Dominant Color and Scalable Color, is compared to that of HSV autocorr...
متن کاملProperties of dominant color temperature descriptor
The concept of color temperature is derived from an innate characteristics of the human visual system. It is formulated as a visual feature referring to a kind of perceptual feeling about perceived light. Color temperature has also a physical-based definition, and hence, color temperature of observed scenes and visual objects can be modelled in a mathematical way as a one-parameter characterist...
