With the increasing demand for the development of high quality remote sensing image techniques, the problem of image degradation causing by pixel-response non-uniformity (PRNU) is becoming a key issue. In this paper, a novel PRNU correction algorithm is proposed and implemented on FPGA hardware platform. Firstly, the characteristic of the CCD noise is analyzed. Secondly, the degradation model of pixel-response...
This paper addresses the problem of image compression in remote sensing applications. Compared with other still images, remote-sensing images are characterized with complex textures and weak local correlation. As a fact, RS images often contain richly directional attributes, which can be commonly approximated as linear edges on a local level. Most of current algorithms of image compression have not...
