Abstract

CCD CAMERA is a multi-spectral sensor placed on CBERS02 satellite platform. The imaging technique in this sensor is pushbroom. There are some vertical noises in the images captured by this sensor all because of unadjustment between different adjacent detectors in the CCD-Camera sensor, internal changes in detectors, mis-calibration and low values of signal to noise ratios. These noises for homogeneous surfaces in level2 products are more profound. The presence of these noises in the images renders correct interpretation and extraction of information hard. In this study, for correction of noise a method based on the spatial momentum adjustment is introduced. In the proposed method the statistical momentums such as mean and standard deviation of the column in each band are used for stabilization of the statistical characteristics of the detector array to their reference values. In the simulated image for vertical noise, 97% accuracy in denoising was achieved. Moreover 16% increase of the image quality in band1 and 19% in band2 shows the acceptable performance of the method in denoising. Also by implementing the method on band1 and 2 images, the standard deviation decreased from 9.47 to 9.01 and 5.72 to 5.25 respectively. This proves that the method was a success.
