Abstract: Methods, systems, and apparatus, including computer programs encoded on computer-storage media, for multi-camera video stabilization. In some implementations, a video capture device has a first camera and a second camera. The video capture device provides a digital zoom capability permitting user-specified magnification changes within a digital zoom range during video recording. The video capture device is configured to use video data from different cameras over different portions of the digital zoom range. The video capture device can process image data captured using the second camera by applying a set of transformations including (i) a first transformation to a canonical reference space for the second camera, (ii) a second transformation to a canonical reference space for the first camera, and (iii) a third transformation to apply electronic image stabilization to image data in the canonical reference space for the first camera.

Abstract: A method for preparing a conductive biomimetic skin scaffold material with self-repairing function includes the following steps: adding 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride to a homogeneous dispersion of acidified carbon nanotubes, poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS), and gelatin to cross-link to obtain a conductive composite colloid; and injecting the conductive composite colloid into a mold, aging at ?4-4° C. for 12-24 hours, and then soaking in a phosphate-buffered saline (PBS) solution with a pH of 7.0-7.4 for 12-24 hours to obtain the conductive biomimetic skin scaffold material.

Abstract: An example method includes outputting, for display, a frame having one or more images that are captured by at least one camera device; responsive to receiving an input to select the frame, storing the frame as a reference frame having one or more reference images, wherein the one or more reference images include the one or more images of the frame; determining, based on the reference images included in the reference frame, a reference pose of the at least one camera device; outputting, for display, a current frame having current images captured by the at least one camera device; determining, based on the current images, a current pose of the at least one camera device; and responsive to determining that the current pose is different from the reference pose, outputting an indication of instructions to manipulate the at least one camera device from the current into the reference pose.
