Abstract: Methods and system for creating and managing personalized fonts. Personalized fonts are created by applying personalization parameters to a base font using a style application method or module such as a neural style transformation. The personalized fonts may be transferred to recipients of textual communications to enable the recipient to read messages from a sender in the personalized font of the sender.

Abstract: A virtual shockwave creation system comprises an eyewear device that includes a frame, a temple connected to a lateral side of the frame, and a depth-capturing camera. Execution of programming by a processor configures the virtual shockwave creation system to generate, for each of multiple initial depth images, a respective shockwave image by applying a transformation function to the initial three-dimensional coordinates. The virtual shockwave creation system creates a warped shockwave video including a sequence of the generated warped shockwave images. The virtual shockwave creation system presents, via an image display, the warped shockwave video.

Abstract: A depth sculpturing system comprises an eyewear device that includes a frame, a temple connected to a lateral side of the frame, and a depth-capturing camera. The depth sculpturing system further includes a user input device. Execution of programming by a processor configures the depth sculpturing system to perform functions to track, via the user input device, motion of a two-dimensional input selection from an initial touch point to a final touch point. The depth sculpturing system determines a rotation matrix between an initial ray and a final ray that project to the initial touch point and the final touch point, correspondingly. The depth sculpturing system generates a depth sculptured image by applying the rotation matrix to vertices of an initial depth image. The depth sculpturing system presents, via an image display, the depth sculptured image.

Abstract: Three-dimensional image calibration and presentation for eyewear including a pair of image capture devices is described. Calibration and presentation includes obtaining a calibration offset to accommodate flexure in the support structure for the eyewear, adjusting a three-dimensional rendering offset by the obtained calibration offset, and presenting the stereoscopic images using the three-dimension rendering offset.

Abstract: A virtual wave creation system comprises an eyewear device that includes a frame, a temple connected to a lateral side of the frame, and a depth-capturing camera. Execution of programming by a processor configures the virtual wave creation system to generate, for each of multiple initial depth images, a respective wave image by applying a transformation function that is responsive to a selected input parameter to the initial three-dimensional coordinates. The virtual wave creation system creates a warped wave video including a sequence of the generated warped wave images. The virtual wave creation system presents, via an image display, the warped wave video.

Abstract: Disclosed are systems, methods, and non-transitory computer-readable media for varied depth determination using, stereo vision and phase detection auto focus (PDAF). Computer stereo vision (stereo vision) is used to extract three-dimensional information from digital images. To utilize stereo vison, two optical sensors are displaced horizontally from one another and used to capture images depicting two differing views of a real-world environment from two different vantage points. The relative depth of the objects captured in the images is determined using triangulation by comparing the relative positions of the objects in the two images. For example, the relative positions of matching objects (e.g., features) identified in the captured images are used along with the known orientation of the optical sensors (e.g., distance between the optical sensors, vantage points the optical sensors) to estimate the depth of the objects.

Abstract: A method for correcting a bending of a flexible device is described. In one aspect, the method includes accessing feature data of a first stereo frame that is generated by stereo optical sensors of the flexible device, the feature data generated based on a visual-inertial odometry (VIO) system of the flexible device, accessing depth map data of the first stereo frame, the depth map data generated based on a depth map system of the flexible device, estimating a pitch-roll bias and a yaw bias based on the features data and the depth map data of the first stereo frame, and generating a second stereo frame after the first stereo frame, the second stereo frame based on the pitch-roll bias and the yaw bias of the first stereo frame.

Abstract: A photo filter (e.g., artistic) light field effect system comprises an eyewear device that includes a frame, a temple connected to a lateral side of the frame, and a depth-capturing camera. Execution of programming by a processor configures the photo filter light field effect system to apply a photo filter selection to: (i) a left raw image or a left processed image to create a left photo filter image, and (ii) a right raw image or a right processed image to create a right photo filter image. The photo filter light field effect system generates, a photo filter light field effect image with an appearance of a spatial rotation or movement, by blending together the left photo filter image and the right photo filter image based on a left image disparity map and a right image disparity map.

Abstract: A photo filter (e.g., artistic/stylized painting) light field effect system includes an eyewear device having a frame, a temple connected to a lateral side of the frame, and a depth-capturing camera. Execution of programming by a processor configures the stylized image painting effect system to apply a photo filter selection to: (i) a left raw image or a left processed image to create a left photo filter image, and (ii) a right raw image or a right processed image to create a right photo filter image. The stylized image painting effect system generates a photo filter stylized painting effect image with an appearance of a spatial rotation or movement, by blending together the left photo filter image and the right photo filter image based on a left image disparity map and a right image disparity map.
