Property and Removal of Jitter in Beijing-1 Small Satellite Panchromatic Images
نویسندگان
چکیده
Attitude of the Small satellite is prone to be affected by external disturbing factors due to its small inertia. As for Beijing-1 small satellite, jitter is induced and exhibited in the images taken while the outside disturbance is intense. The jitter is manifested as jagged lines and edges in the images, leading to distortion of geometric property of the objects. In this paper, properties of the Beijing-1 small satellite jitter are explored based on analyses of affections of attitude jitter with diverse frequency and directions to the imaging process. Accordingly an image based jitter removal method is brought up, the proposed method removes jitter effectively and can be introduced into practical production process.

Fusion of Panchromatic and Multispectral Images Using Non Subsampled Contourlet Transform and FFT Based Spectral Histogram (RESEARCH NOTE)
Image fusion is a method for obtaining a highly informative image by merging the relative information of an object obtained from two or more image sources of the same scene. The satellite cameras give a single band panchromatic (PAN) image with high spatial information and multispectral (MS) image with more spectral information. The problem exists today is either PAN or MS image is available fr...

Road Detection in Panchromatic SPOT Satellite Images
The goal of this study is to detect the main road network in high resolution, panchromatic SPOT satellite images. The applications of automatic road detection have attracted considerable interest in this problem [1–4], but no present system is completely satisfactory from the point of view of detection time, image size and required human intervention. We describe an automatic procedure for road...
