Journal Title: Вісник Національного університету "Львівська політехніка", серія "Радіоелектроніка та телекомунікації" - Year 2015, Vol 818, Issue 2015
Abstract
The methods, their advantages and disadvantages, of fusion a low-resolution multispectral and panchromatic high-resolution image in high-resolution color image are considered. Is proposed a method to provide high-resolution, which is based on the use of subpixel processing, the essence of which is the handling of input data in the form of a CCD sensor arrays shifted by a half pixel with respect to each other. Using of subpixel imaging technology can improve the device resolution, or in the preservation of the low resolution, to reduce the system focal length and reduce the weight and volume of the optical system, which is very important for monitoring systems. The flow charts of algorithms to improve the multispectral images resolution using of subpixel image processing are synthesized. The simulation results of the proposed method and the obtained synthesized color images with high resolution are presented. The complexity and speed of the proposed method are calculated. As a result it was succeeded effectively to improve the resolution and formation quality of multispectral image.
