摘要： Systems and methods for optimizing the formulation of materials are provided. The systems and methods employ a data-driven, iterative approach to derivate optimal material formulations. One portion of the system includes a sample automation system that outputs the material samples to be tested, and a second portion of the system includes an optimization engine that analyzes data extracted from the material samples and generates additional formulations for materials to be printed and tested. This process continues so that optimal material formulations can be determined based on desired mechanical properties of the material to be optimized. The optimization engine can further be capable of predicting results of formulation that have not yet been tested and using those predictions to further drive the next suggested materials to be tested.

摘要： Devices and methods are described that provide printing of three-dimensional objects using reactive materials such as materials that result in a polyurethane formulation. Three-dimensional printing in accordance with the present disclosure can be performed using an inkjet printer or other systems that deposit or dispense material. A formulation made up of two or more reactive materials and, optionally, one or more UV-curable materials is also provided. The materials can be jetted based on a desired configuration to achieve a maximum reaction between materials, and can be based on desired jetting or molar ratios. By heating or applying energy on the jetted materials, their reaction and related solidifying can be accelerated. Corrective printing is also provided for, and can be used at desired intervals to eliminate printing errors relative to the object as modeled. Systems and methods used in conjunction with all of the same are provided.

摘要： A system for determining the gaze direction of a subject includes a camera, a computing device and a machine-readable instruction set. The camera is positioned in an environment to capture image data of head of a subject. The computing device is communicatively coupled to the camera and the computing device includes a processor and a non-transitory computer-readable memory. The machine-readable instruction set is stored in the non-transitory computer-readable memory and causes the computing device to: receive image data from the camera, analyze the image data using a convolutional neural network trained on an image dataset comprising images of a head of a subject captured from viewpoints distributed around up to 360-degrees of head yaw, and predict a gaze direction vector of the subject based upon a combination of head appearance and eye appearance image data from the image dataset.

摘要： Multi-view autostereoscopic displays provide an immersive, glasses-free 3D viewing experience, but they preferably use correctly filtered content from multiple viewpoints. The filtered content, however, may not be easily obtained with current stereoscopic production pipelines. The proposed method and system takes a stereoscopic video as an input and converts it to multi-view and filtered video streams that may be used to drive multi-view autostereoscopic displays. The method combines a phase-based video magnification and an interperspective antialiasing into a single filtering process. The whole algorithm is simple and may be efficiently implemented on current GPUs to yield real-time performance. Furthermore, the ability to retarget disparity is naturally supported. The method is robust and works transparent materials, and specularities. The method provides superior results when compared to the state-of-the-art depth-based rendering methods. The method is showcased in the context of a real-time 3D videoconferencing system.

摘要： A method for producing a hologram representative of a subject three-dimensional scene includes receiving and storing input digital data characterizing a first image of the subject three-dimensional scene. The method further includes processing the data in a neural network that has been trained to transform the input digital data into a holographic representation of the subject three-dimensional scene, the representation containing phase information characterizing depth and parallax of the scene. The method also includes providing an output of the holographic representation of the subject three-dimensional scene.
