Self-regularizing inverse filter for image deblurring

A method includes capturing, by a camera disposed behind a display panel of an electronic device, an original image through a semi-transparent pixel region of the display panel. The original image is associated with one or more predetermined point spread functions (PSFs) and includes one or more blurring artifacts. The method further includes estimating an optimal regularization parameter for the original image based on the one or more predetermined PSFs and the one or more blurring artifacts, applying a self-regularizing inverse filter, such as a fast self-regularizing inverse filter, to the original image based on the estimated regularization parameter, and generating a deblurred image based on the self-regularizing inverse filter. Generating the deblurred image includes reconstructing the original image utilizing the self-regularizing inverse filter to remove the one or more blurring artifacts.

Characterization of optical distortion in a head mounted display

An optical profiling system characterizes distortion of a head-mounted display (HMD) under test. The optical profiling system includes a camera assembly and a controller. The controller provides presenting instructions that cause the HMD under test to present test patterns and also provides imaging instructions that cause the camera assembly to capture images of the test patterns presented by the HMD under test. The camera assembly includes one or more characterization cameras. A characterization camera is configured to mimic movement of a human eye and is positioned in an eye box region of the HMD under test. Using the images captured by the camera assembly, the controller measures distortion of the HMD under test. The controller may generate a report charactering the HMD under test based on the measured distortion.

Determining positions and orientations of objects

Methods and apparatus for determining poses of objects acquire plural images of the objects from different points of view. The images may be obtained by plural cameras arranged in a planar array. Each image may be processed to identify features such as contours of objects. The images may be projected onto different depth planes to yield depth plane images. The depth plane images for each depth plane may be compared to identify features lying in the depth plane. A pattern matching algorithm may be performed on the features lying in the depth plane to determine the poses of one or more of the objects. The described apparatus and methods may be applied in bin-picking and other applications.
