Abstract: The condition of the plenoptic imaging system is determined using views capturing a calibration object by the plenoptic imaging system. The plenoptic imaging system accesses at least two views from the plenoptic imaging system and determines a measure of divergence from the reference condition based on the view images associated with each view. Each of the accessed views can have a known relationship when the plenoptic imaging system is in the reference condition. Based on the measure of divergence and the known relationship, the plenoptic imaging system can indicate a variation from the reference condition. The variation can indicate misalignment or degradation of the plenoptic imaging system. This determination of divergence and indication of variation from the reference condition can be included in a variety of calibration procedures.

Abstract: An application delivery controller for improving remote healthcare services is disclosed. The application delivery controller may be configured to provide improved service routing and security. In some implementations, the application delivery controller may receive a service request from a client device. The application delivery controller may determine routing parameters based on a requested service of the service request, authenticate access from the client device based on the requested service, a security zone of the requested service, and a token, and route the requested service to the client device based on the routing parameters and the authenticated access.

Abstract: One aspect determines centroids of a plenoptic image, which correspond to the center view of the plenoptic image. A search band spanning a range of different values along a search direction (e.g., range of ?y) is determined. Multiple slices of the plenoptic image are taken at different values of the search coordinate (i.e., different y values). Because the plenoptic image has a periodic structure imposed by the periodicity of the microlens array, each slice will have a strong frequency component at this fundamental frequency. A slice corresponding to the centroid location (i.e., value of y at the centroid) is selected based on analysis of these frequency components. In one approach, the slice with the weakest component at this fundamental frequency is selected as the centroid. A similar approach can be performed in the orthogonal direction to obtain the two-dimensional coordinates of the centroids.

Abstract: Calibration for a plenoptic imaging system. The plenoptic imaging system includes a detector array that is subdivided into superpixels. A plenoptic image captured by the detector array of the plenoptic imaging system is accessed. For a row of superpixels, a slice is selected through the row, the selected slice having a Fourier transform with a stronger fundamental component compared to other slices through the row. A pitch of the row of superpixels is determined based on a frequency of the fundamental component of the selected slice. A rotation of the row of superpixels is determined based on a rotation of the selected slice.

Abstract: A light field imaging system captures different images provide views that are shifted by sub-pixel amounts relative to one another. These views can be combined to produce a higher resolution digital image of the object.

Abstract: Embodiments of the present disclosure provide a method that comprises receiving a first stream of video frames at a first frame rate and generating a second stream of video frames at a second frame rate. The method also comprises interpolating between a pair of adjacent video frames of the first stream of video frames to produce a first number of interpolated intermediate video frames in a particular sequence of the intermediate video frames. The method further comprises duplicating at least one of the adjacent video frames of the pair of adjacent video frames to produce a second number of duplicated intermediate video frames in the particular sequence of the intermediate video frames. The method further comprises, in response to a change in observed interpolation quality, dynamically changing the first number of interpolated intermediate video frames and the second number of duplicated intermediate video frames.

Abstract: Embodiments of the present disclosure provide a method that comprises receiving a motion-interpolated pixel of an interpolated video frame, wherein the motion-interpolated pixel is based at least in part on a pair of anchor video frames. The method further comprises blending the motion-interpolated pixel with one or more anchor pixels of the pair of anchor video frames to produce a temporally filtered pixel, wherein the one or more anchor pixels correspond in position to the motion-interpolated pixel of the interpolated video frame. The method also comprises substituting the temporally filtered pixel for the motion-interpolated pixel in the interpolated video frame.
