Abstract: Secure rendering system that creates ray tracing samples with obfuscated positions, so that images can only be viewed by an authorized consumer able to recover the sample positions. Obfuscation of ray directions is integrated into the rendering process, for example by incorporating encryption into a lens shader. The rendering system never stores or transmits an image without obfuscating positions, so even the rendering system cannot see the image it is rendering. Embodiments may use public key cryptography, so that encryption of sample positions is done with a public key, and only the owner of the secret private key can view the rendered image. Since keys are asymmetric, the rendering system cannot decrypt the obfuscated samples. Piracy of rendered images is therefore mitigated. Some compositing operations may be performed on the secure rendering output prior to decrypting sample positions; for example, colors may be modified globally or for selected objects.

Abstract: Methods and systems for image texture enhancement are disclosed. In some aspects, texture information for a plurality of object types is stored in a database. Objects are recognized in an image, and the type of each recognized object is identified.

Abstract: Techniques for planar region-guided estimates of 3D geometry of objects depicted in a single 2D image. The techniques estimate regions of an image that are part of planar regions (i.e., flat surfaces) and use those planar region estimates to estimate the 3D geometry of the objects in the image. The planar regions and resulting 3D geometry are estimated using only a single 2D image of the objects. Training data from images of other objects is used to train a CNN with a model that is then used to make planar region estimates using a single 2D image. The planar region estimates, in one example, are based on estimates of planarity (surface plane information) and estimates of edges (depth discontinuities and edges between surface planes) that are estimated using models trained using images of other scenes.

Abstract: Described herein are methods and systems for texturing a three-dimensional (3D) model using photogrammetry. A sensor captures scans of a physical object, including related pose information, and color images corresponding to each scan. A computing device generates a 3D mesh of the physical object. The computing device preprocesses the color images to remove blurry images and detect textured regions of the object in each non-blurry image.

The computing device generates texture coordinates for the 3D mesh by segmenting the mesh, parameterizing the segments, and packing the parameterized segments into a texture atlas. The computing device paint the texture atlas using the color images that have optimized pose information to generate a model having texture coordinates for each vertex.

Abstract: Structured light active sensing systems transmit and receive spatial codes to generate depth maps. Spatial codes can't be repeated within a disparity range if they are to be uniquely identified. This results in large numbers of codes for single transmitter/single receiver systems, because reflected ray traces from two object locations may be focused onto the same location of the receiver sensor, making it impossible to determine which object location reflected the code. However, the original code location may be uniquely identified because ray traces from the two object locations that focus onto the same location of the first receiver sensor may focus onto different locations on the second receiver sensor. Described herein are active sensing systems and methods that use two receivers to uniquely identify original code positions and allow for greater code reuse.
