1. A method of image deconvolution, comprising: capturing a video comprising a plurality of frames using an imaging device; measuring a sharpness degradation metric for the video, wherein measuring a sharpness degradation metric for the video comprises: determining a mean image in the video using a subset of frames from the plurality of frames of the video; determining a first sharpness metric for the mean image; determining a second sharpness metric for a frame from the plurality of frames; and dividing the first sharpness metric by the second sharpness metric; determining one or more parameters of a point spread function (PSF) corresponding to the sharpness degradation metric; performing deconvolution on at least one frame of the video using the PSF with the one or more parameters.
