Embodiments of the present application provide a browser-based frame extraction method. The method includes: monitoring a target operation of a user on a target page of a browser; obtaining a local video file associated with the target operation; and extracting a plurality of target frames from the local video file using a WebAssembly video parser in the browser. This disclosure enables a browser to independently complete operations such as frame extraction on videos in various encoding formats so as to reduce server load.

Browser-based frame extraction method and system

A wavefront sensor includes a mask and a sensor utilized to capture a diffraction pattern generated by light incident to the mask. A reference image is captured in response to a plane wavefront incident on the mask, and another measurement image is captured in response to a distorted wavefront incident on the mask. The distorted wavefront is reconstructed based on differences between the reference image and the measurement image.
