Stylized rendering is the process of generating images or videos that mimic the visual appeal of pieces of art, expressing the visual and emotional characteristics of artistic styles. A major problem in stylizing videos is the absence of temporal coherence, something that results in flickering of the structural drawing elements (such as brush strokes or curves), also known as swimming. In the first part of this talk, I will describe techniques that are used for stylizing videos with temporal coherence in the AnimVideo rendering tool. The temporal coherence is achieved by combining a segmentation and an optical flow methods into a method called constrained optical flow. The flow maps are then used to correctly move, remove or add structural drawing elements. In the second part of the talk, l will describe some stylized rendering methods that were implemented in the AnimVideo tool.
