Abstract
A method and a digital filter, for use with photo and video images, includes using a camera or video camera equipped with sensors and an electronic shutter to capture a plurality of frames of low resolution and producing one frame of high resolution. A plurality of frames are exposed. Initial images are in the form of a continuous sequence of frames with high-speed capture. The frequency of the frames is inversely proportional to the magnitude of that part of the light-sensitive region of the sensor that is being scanned. The initial images are aligned and an enhanced image is produced. The enhanced image is filtered using a nonlinear filter which includes a neural network that is pretrained using a test image including radial and sinusoidal test charts, as well as reference points.
