Very low bit rate watercolor video
We developed a very low bit rate watercolor-like video form, which is constructed with a bi-level Y luminance component and a number of UV chrominance combinations. The bi-level Y-component outlines the features of an image and the UV-combinations describe the basic color information of the image. The UV combinations are dynamically chosen during encoding. The resultant video looks better than bi-level video and its bit rate is still much lower than that of full-color video. Watercolor video can be used in video broadcast and communication in very low bandwidth networks.
