摘要： A set of feature points for defining features of a face is detected in a target image and a reference image. The target image is warped to accommodate a selected feature from the reference image using the set of feature points and a set of three-dimensional models. The reference image is warped to a pose of the target image using the set of feature points and the set of three-dimensional models. The selected feature is copied from the reference image to the target image.

摘要： Methods and apparatus for generating context-sensitive, co-salient thumbnails are described. Co-salient thumbnails may effectively convey more useful information than conventional thumbnails while using the same or similar display space. As such, co-salient thumbnails may make it easier for a user to locate a particular image in a large collection of similar images. In some embodiments, for each of a plurality of patches in a first image, an illustrative method may identify a corresponding similar patch in a second image based on one or more similarity measures. The method may then determine a distance from each of the plurality of patches to its corresponding similar patch and select a crop in the first image relative to the second image based on the determined distance. Optionally, the method may repeat these operations in the opposite direction to select a crop in the second image relative to the first image.

摘要： Techniques for illumination-guided example-based stylization of 3D renderings are described. In implementations, a source image and a target image are obtained, where each image includes a multi-channel image having at least a style channel and multiple light path expression (LPE) channels having light propagation information. Then, the style channel of the target image is synthesized to mimic a stylization of individual illumination effects from the style channel of the source image. As part of the synthesizing, the light propagation information is applied as guidance for synthesis of the style channel of the target image. Based on the guidance, the stylization of individual illumination effects from the style channel of the source image is transferred to the style channel of the target image. Based on the transfer, the style channel of the target image is then generated for display of the target image via a display device.

摘要： Appearance transfer techniques are described in the following. In one example, a search and vote process is configured to select patches from the image exemplar and then search for a location in the target image that is a best fit for the patches. As part of this selection, a patch usage counter may also be employed in an example to ensure that selection of each of the patches from the image exemplar does not vary by more than one, one to another. In another example, transfer of an appearance of a boundary and interiors regions from the image exemplar to a target image is preserved.

摘要： Various embodiments of methods and apparatus for face fitting are disclosed. In one embodiment, sets of two-dimensional local feature points on a face in each image of a set of images are identified. The set of images includes a sequence of frames a video stream. A three-dimensional face model for the face in the each image is generated as a combination of a set of predefined three-dimensional face models. In some embodiments, the generating includes reducing an error between a projection of vertices of the set of predefined three-dimensional face models and the two-dimensional local feature points of the each image, and constraining facial expression of the three-dimensional face model to change smoothly from image to image in the sequence of video frames.

摘要： Three dimensional models corresponding to a target image and a reference image are selected based on a set of feature points defining facial features in the target image and the reference image. The set of feature points defining the facial features in the target image and the reference image are associated with corresponding 3-dimensional models. A 3D motion flow between the 3-dimensional models is computed. The 3D motion flow is projected onto a 2D image plane to create a 2D optical field flow. The target image and the reference image are warped using the 2D optical field flow. A selected feature from the reference image is copied to the target image.

摘要： Methods and apparatuses for generating thumbnail summaries for image collections are described. Thumbnails summaries may be representative of the image collection while being disjoint from each other. In some embodiments, a method may sample crops from some or all images in an image collection. From these candidate crops, the method may select representative but disjoint crops. In some embodiments, a desired representativeness and/or disjointedness of the candidate crops may be defined by a user. The method may then generate and/or select thumbnail summaries for the collection of images based at least in part on the selected candidate crops.
