Editing Dynamic Textures by Changing Model Parameters

3 minute read

The operation that by processing video data allows producing new video data in Computer Graphics is known as Video-Based Rendering (VBR). Developing new VBR techniques is important because they allow to quickly synthesize new photo-realistic scenes (because of the origin of the data) without having to develop and simulate a synthetic model of the scene. The difficulty is in developing editing techniques that, once applied to the original data, can produce the desired perceptual effect. (Doretto & Soatto, 2002) and (Doretto & Soatto, 2003) represent a VBR approach that allows learning dynamic texture models from video, and then simulating them for synthesizing/rendering new unseen videos. Modeling the spatial stationarity enables the synthesis not only in time, but also in space (so the frame size can grow) (Doretto et al., 2004). It is shown how dynamic texture model parameters can be edited (changed) online, and mapped to meaningful perceptual changes, such as the spatial frequency content, the speed, the time axis, or the intensity of the visual process. This means that from a video sequence of sea waves one could, for instance, produce a new video with a rougher or smoother sea movement, according to the desire.
