Digital radiography system is widely used for noninvasive security check and medical imaging examination. However, the system has a limitation of lower image quality in spatial resolution and signal to noise ratio. In this study, we explored whether

The internal geometric distortion of charge-coupled-device ( ccd ) chips degrades the internal geometric accuracy of satellite images. Even if a large number of ground control points (GCPs) are used for geometric correction, the satellite images cann

Statistical noise may degrade the x-ray image quality of digital radiography (DR) system. This corruption can be alleviated by extending exposure time of detectors and increasing the intensity of radiation. However, in some instances, such as the sec

Design deficiencies and hardware limitations cause a number of issues with the images acquired by Chinese satellites launched before 2012, such as YG-12. The geometric quality of the images recorded by YG-12 cannot match its high resolution because o

With incomplete or noisy projections, algebraic reconstruction technique (ART) algorithms can get better image qualities than convolution back-projection (CBP) algorithm. But, it's too slow to meet the practical industrial requirements. Rotating pola
