SINOPSIS

The scope of problems related to studying the structures, the image elements of which are beyond the resolution of matrix type sensors, has expanded during recently. Thus, the problem of their reconstruction by applying algorithmic and information image processing techniques has become the subject of study. The problems emerging when observing objects, the dimensions of which do not exceed several pixels of matrix of recorder sensors are considered. It is shown that motion of the object with regards to the matrix and use of multiple consecutive frames allows improving the fidelity of shape and true size of the object; in doing so this measurement information can be represented as integrals along the trajectories on a three-dimensional lattice of space-time pixels. The reconstruction of a heterogeneity function of pixels due to application of the controlled motion of the test object and computer tomography methods. The possibility of determining the relative velocity of the object in each of the frames using the blind method is demonstrated. The algorithm of reconstructing images with large non-uniform increment during their arbitrary and controlled relative motion has been elaborated.
