Abstract:
Systems and methods for improving the quality of recognition of the object based on a series of frame images of objects are described herein. A plurality of images depicting the same object are received. A first image is selected from the plurality of images. The first image may be an image with the highest quality from plurality of images. For each image in the plurality of images, motion estimation of elements of an image in the plurality of images and the first image is performed. Based on the results of motion estimation, motion compensation and signal accumulation of the object in the images in the plurality of images using the first image are performed. A high resolution image of the object obtained based on the motion compensation and signal accumulation is generated. Character recognition on the resulting high resolution image is performed.
