摘要： A system and method are disclosed for determining and alerting a user as to whether an object will successfully scan before the post-processing of the scan data. In embodiments, before post-processing of the scan data begins, the scan data is processed by a machine learning algorithm which is able to determine whether and/or how likely the scan data is to return an accurate scanned reproduction of the scanned object. The machine learning algorithm may also suggest new positions for the object in the environment where the scan is more likely to be successful.

摘要： A method for generating a three-dimensional virtual representation includes performing a first scan of the physical object while the physical object has a first position. A displayed visualization of the physical object is generated based on the first scan. Aligning input is received that causes increased correspondence between the displayed visualization and a second position of the physical object. A second scan of the physical object is performed while the object is in the second position. Based on the first scan and the second scan, a three-dimensional virtual representation of the physical object is generated.

摘要： A three-dimensional shape parameter computation system and method for computing three-dimensional human head shape parameters from two-dimensional facial feature points. A series of images containing a user's face is captured. Embodiments of the system and method deduce the 3D parameters of the user's head by examining a series of captured images of the user over time and in a variety of head poses and facial expressions, and then computing an average. An energy function is constructed over a batch of frames containing 2D face feature points obtained from the captured images, and the energy function is minimized to solve for the head shape parameters valid for the batch of frames. Head pose parameters and facial expression and animation parameters can vary over each captured image in the batch of frames. In some embodiments this minimization is performed using a modified Gauss-Newton minimization technique using a single iteration.

摘要： A face cartooning system is described. In one implementation, the system generates an attractive cartoon face or graphic of a user's facial image. The system extracts facial features separately and applies pixel-based techniques customized to each facial feature. The style of cartoon face achieved resembles the likeness of the user more than cartoons generated by conventional vector-based cartooning techniques. The cartoon faces thus achieved provide an attractive facial appearance and thus have wide applicability in art, gaming, and messaging applications in which a pleasing degree of realism is desirable without exaggerated comedy or caricature.

摘要： Techniques for providing localized color transfer are disclosed. In some aspects, a user may select a source region of a source image and a destination region of a destination image. The source region and the destination region may be associated by a designator to create a color transfer pair. A localized color transfer based on the color style of the source region may be implemented to modify the destination region color style. Further aspects may include optimizing the destination image to reduce discontinuities resulting from the color transfer and enabling the user to select regions of the destination image which are not modified by localized color transfer.

摘要： The present invention involves a new system and method for synthesizing textures from an input sample. A system and method according to the present invention uses a unique accelerated patch-based sampling system to synthesize high-quality textures in real-time using a small input texture sample. The patch-based sampling system of the present invention works well for a wide variety of textures ranging from regular to stochastic. Potential feature mismatches across patch boundaries are avoided by sampling patches according to a non-parametric estimation of the local conditional Markov Random Field (MRF) density function.

摘要： A system and process for adding a photorealistic rendering of a body of water to a virtual 3D scene or image and creating a video therefrom having interactive water effects. A region of water is added to an image by adding an area depicting the original scene as it would appear if reflected by still body of water. Then, the appearance of the added water region is distorted over a series of image frames in such a way as to simulate how the reflected scene would look if the surface of the water were in motion. The water can have dynamic waves and the user can interact with the water in numbers of ways, including generating ripples on the water surface and creating rain. In addition, these effects can be achieved at full screen resolution with the use of the latest graphics hardware by employing a texture shifting technique.
