摘要： A method, system, and computer-readable storage medium for determining an estimate of sensor sensitivity associated with an image. A noise level of an image is determined, then an estimate of sensor sensitivity associated with the image is automatically determined, e.g., by a trained classifier based on the determined noise level. Additionally, the sensor sensitivity estimate can be used to determine scene brightness.

摘要： A method, system, and computer-readable storage medium for categorizing digital images. A plurality of semantic category scores for a digital image are determined via application of a corresponding plurality of classifiers. A semantic category profile for the image is automatically determined based on the plurality of semantic category scores, where the semantic category profile characterizes semantic content of the image, and is useable to perform semantic based operations with respect to the image.

摘要： Methods and apparatus for procedural directional texture generation. A procedural directional texture generation method may, for example, be used to design hair or hairstyles. The method may obtain one or more strokes, one or more optional masks, and one or more optional user maps. One or more interpolated orientation maps may be generated from the input. The orientation maps, possibly along with one or more optional user maps, may be used to compute synthetic low-frequency lighting. A noise map may be generated at one or more frequencies and used, along with the interpolated maps, to generate high-frequency lighting. Alternatively, a flow-guided texture synthesis method may be used to generate high-frequency lighting. The low- and high-frequency lighting may then be combined to generate a desired frequency spectrum. Color may be added to the full structure, or alternatively color may be added at an earlier step.

摘要： Methods and apparatus for directional texture generation using image warping. An image warping directional texture generation method may, for example, be used to design hair or hairstyles. The method may obtain one or more user strokes via a provided brush or other user interface element to paint directional texture, such as hair, onto a target image. Primitives, such as strands, wisps, partings, etc., may be used to paint the directional texture. After the user applies a stroke to paint a primitive or a portion of a primitive onto the target image, the primitive may be automatically adjusted to fit the primitive to the stroke, handle distortion artifacts, and blend the primitive into the existing image. The user may continue to apply strokes until satisfied with the overall result.

摘要： Methods and apparatus for marker-based stylistic rendering may be used to automatically synthesize the stylistic range of various stylistic rendering techniques. An image processing pipeline may automatically generate stylistic images, such as Hedcut stipple images. Using virtual markers to determine locations in the image to which physical markers are to be attached, the tone of an original source image may be automatically reproduced via placement of stipple dots or other physical markers, while at the same time allowing for stylistic refinement of placement and appearance of the physical markers, e.g. along strong features in the source image.

摘要： Methods and apparatus for directional texture generation using flow-guided, sample-based texture synthesis. A texture synthesis directional texture generation method may, for example, be used to design hair or hairstyles. The method may obtain one or more strokes, one or more optional masks, one or more optional user maps, and directional texture samples. A target region and one or more samples may be divided into patches. For each patch in the target region, a matching patch from the samples may be located according to one or more features to generate a similarity map. The patches in the target region may then be replaced with the patches from the samples according to the similarity map. To match sample patches to target region patches based on features such as color and brightness, a procedural directional texture generation method may be used as a pre-processing step.

摘要： Methods, apparatus, and computer-readable storage media for stereo drawing that enable the creation of stereoscopic image pairs. A stereo drawing system may present 3D shape(s) via a user interface (UI). The user can position and rotate a 3D shape, for example via direct manipulation technology such as motion tracking technology. A drawing surface may be mapped to an input device via which input strokes may be applied to the surface. The input strokes are mapped locally onto the surface, thereby allowing the user to draw onto a well-defined shape in 3D space. The stereo drawing system maps what is drawn onto the drawing surface; the geometry of the drawing surface provides depth information so that stereoscopic image pairs can be automatically generated.

摘要： The systems and methods described herein may allow diffusion curve images to be displayed by a variety of applications without requiring specialized graphics hardware to render the images. The system may provide mechanisms to convert a diffusion curve representation to an alternate representation in a scalable, portable format. The conversion may include a tessellation operation, and may produce a mesh of shapes (e.g., triangles) for which diffusible attribute values (e.g. color and blur) are assigned to each node. Tessellating an image may include generating a piecewise linear approximation of the diffusion curves and triangulating the image to generate the mesh. Color values for each channel may be assigned by solving a sparse linear system in the triangle domain. The alternate representation may be displayed by another application using various interpolation techniques. The alternate representation may be resolution-independent and compact, as compared to other representations used to display diffusion curve images.
