Video Cubism (original) (raw)

We present new non-photorealistic (NPR) rendering tools for video. Inspired by the Cubist and Futurist art movements that questioned previous notions of space and time within paintings, we view an input video as a space-time cube of data, rather than a series of static frames. Our tools process the video as a whole to produce a set of stroke-solids, units for rendering that appear over multiple frames in the resulting NPR video. Depending on stylistic considerations and video content, each stroke solid is encoded with parameters such as location, size, curvature, orientation, color values, or other relevant information. A non-photorealistic video is constructed interactively by compositing slices of the stroke solids. These slices, or strokes, are rendered as multi-textured sprites. The textures for each stroke may be derived from a pre-defined texture atlas and/or drawn from the underlying video itself. Many of the parameters that define the appearance of a stroke are set at runtim...

Stroke surfaces: Temporally coherent artistic animations from video

2005

Abstract The contribution of this paper is a novel framework for synthesizing nonphotorealistic animations from real video sequences. We demonstrate that, through automated mid-level analysis of the video sequence as a spatiotemporal volume-a block of frames with time as the third dimension-we are able to generate animations in a wide variety of artistic styles, exhibiting a uniquely high degree of temporal coherence.

Cubist style rendering from photographs

2003

Abstract The contribution of the paper is a novel nonphotorealistic rendering (NPR) technique, influenced by the style of Cubist art. Specifically, we are motivated by artists such as Picasso and Braque, who produced art work by composing elements of a scene taken from multiple points of view; paradoxically, such compositions convey a sense of motion without assuming temporal dependence between views.

Video Paintbox: The fine art of video painting

2005

We present the Video Paintbox; a novel system capable of transforming video into stylised animations. Our system solves the problem of temporally coherent painting for a wide class of video, and is able to introduce cartoon-like motion emphasis cues. Coherent painting in video is a long-standing problem that is associated with the difficulties in placing, orienting, and sizing paint strokes over time.

Stroke surfaces: a spatio-temporal framework for temporally coherent nonphotorealistic animations

2003

Abstract The contribution of this paper is a novel framework for the automated synthesis of non-photorealistic animations from video sequences. Our approach is unique in that we interpret the source video sequence as a spatio-temporal voxel volume, with time as the third dimension. Video frames are segmented into homogeneous regions, and heuristic associations between regions formed over time to produce a collection of conceptually high level spatio-temporal objects.

Non-Photorealistic Video Synthesis for Artistic User Experience on Mobile Devices

2013

This paper presents analysis/synthesis strategies for generating abstract, creative representations via the camera input on a mobile device. Mobile devices are well suited for interactive video processing since they are simultaneously capable of image capture, display, and manipulation. Analysis/synthesis methods are particularly powerful in interactive arts projects as they enable even drastic manipulations of the input image while still maintaining fundamental aspects of its original identity. Moreover, by using abstract synthesis elements (i.e., coherent elements larger than single pixels), we are able to directly interact with the image and to manipulate its final output. We describe some of the exciting capabilities of video processing and interaction on mobile devices and introduce a series of mobile applications that use analysis/synthesis techniques.

INTERACTING WITH STROKE-BASED NON-PHOTOREALISTIC RENDERING ON LARGE DISPLAYS

2008

Since over two decades researchers work on approaches for generating non-photorealistic renditions, that are often inspired by artistic styles. Research in this field has focused on developing algorithms to automatically produce a final rendition. Recently more effort was placed in including the user into the process of creating a non-photorealistic rendition.
