Pixelation reconstruction for image resolution and image data transmission

Abstract

Methods for improving spatial and/or temporal resolution of digital images and for improving image data transmission by a novel technique—back pixelation, which involves data processing and reconstruction of overlaid images from multiple acquisition or multiple sampling. The back pixelation technique may be used for image data acquisition and transmission; it may be applied prospectively or retrospectively. In particular, the methods of this invention may be used in reducing the pixel size of a two-dimensional image or the voxel size of a three dimensional image; producing a two- or three-dimensional image from a multiplicity of images acquired from an object which are capable of overlaying one another by an increment; producing and transmitting a two- or three-dimensional image by multiple acquisitions according to an acquisition matrix; or transmitting a two- or three-dimensional image by reducing or decomposing the image to a plurality of image data packets and transmitting the same. The multiple acquisitions may be arranged by a predetermined temporal schedule. These methods may be advantageously applied in medical imaging, movies and video games, teleimage, and any other areas that involve digital image acquisition, processing, and transmission.
