摘要： A non-photorealistic technique is described for transforming an original image into a sketch image. The technique includes: segmenting the original image into plural regions to produce a segmented image, wherein the regions are demarcated by respective boundaries; shrinking a boundary of at least one of the plural regions in the segmented image to produce a boundary-shrunk image; and modifying at least one color in the boundary-shrunk image to produce the sketch image.

摘要： Multiple schemes and techniques for facilitating presentations with an interactive application are described. For example, an interactive application provides a console view overlay for integrating multiple productivity applications into a graphical user interface (GUI) window. An interactive application can also share a selected display portion of the console view overlay with other interactive applications. As another example, presenters and other audience members can draw on the selected display portion being shared, and the drawn graphics are synchronously displayed by the other interactive applications. Interactive applications, as directed by their users, can join various member groups and specific presentations thereof. Moreover, a user may share content in accordance with membership grouping.

摘要： Knitwear modeling is disclosed. A macrostructure corresponding to a three-dimensional object is generated, based on a stitch pattern and optionally a color pattern. Yarn microstructure is generated and applied to the macrostructure to yield a knitwear model. The stitch positions of the macrostructure can be perturbed to achieve stitch position irregularities. The fluffiness of the yarn microstructure can be controlled. In an alternative embodiment, a two-dimensional knitwear texture is generated, which can then be mapped to a three-dimensional object to yield a knitwear model.

摘要： The techniques and mechanisms described herein are directed to a system for stylizing video, such as interactively transforming video to a cartoon-like style. Briefly stated, the techniques include determining a set of volumetric objects within a video, each volumetric object being a segment. Mean shift video segmentation may be used for this step. With that segmentation information, the technique further includes indicating on a limited number of keyframes of the video how segments should be merged into a semantic region. Finally, a contiguous volume is created by interpolating between keyframes by a mean shift constrained interpolation technique to propagate the semantic regions between keyframes.

摘要： Systems and methods for sketching reality are described. In one aspect, a set of vector primitives is identified from a 2-D sketch. In one implementation, the 2-D sketch is hand-drawn by a user. A 2.5D geometry model is automatically generated from the vector primitives. The 2.5D geometry model is automatically rendered and presented to a user. In one implementation, the user provides 2-D sketch-based user inputs to modify one or more of lighting position, lighting direction, lighting intensity, texture, color, and geometry of the presentation.

摘要： Techniques are described for adaptive changing a displayed foreground color when a conflict between the displayed foreground color and an extracted background color is detected. Upon detection of such a conflict, a new foreground color is selected in accordance with a predetermined legibility criterion. That is, a color pool candidate may be considered to be a viable foreground color if a legibility value for the candidate color in relation to the extracted background color exceeds a predetermined legibility threshold value.

摘要： A method and system for efficient synthesis of photorealistic free-form knitwear, where a single cross-section of yarn serves as the basic primitive for modeling entire articles of knitwear. This primitive, called the lumislice, describes radiance from a yarn cross-section based on fine-level interactions, including occlusion, shadowing, and multiple scattering, among yarn fibers. By representing yarn as a sequence of identical but rotated cross-sections, the lumislice can effectively propagate local microstructure over arbitrary stitch patterns and knitwear shapes. This framework accommodates varying levels of detail and capitalizes on hardware-assisted transparency blending. To further enhance realism, a technique for generating soft shadows from yarn is also introduced.

摘要： An example-based facial sketch system and process that automatically generates a sketch from an input image depicting a person's face. Sketch generation is accomplished by first training the system using example facial images and sketches of the depicted faces drawn with a particular style by a sketch artist. The trained system is then used to automatically generate a facial sketch that simulates the artist's style from an input image depicting a person's face. Nonparametric sampling and a flexible sketch model are employed to capture the complex statistical characteristics between an image and its sketch.
