Estimation of Signal-Noise-Ratio for HJ-1/CCD Data
摘要
The improved local means and local standard deviations method was employed to estimate the SNR of HJ-1/CCD data in this paper.Taking the HJ-1/CCD image acquired on June 26,2011 in Jiuquan area as the test image,the characters of SNR for all HJ-1/CCD bands were analyzed.Result shows that the SNR are different for different HJ-1/CCD bands.Band 3 shows the highest SNR while band 4 shows the lowest SNR.Comparison with the Landsat/TM indicates that HJ-1/CCD exhibits higher SNR except for band 4.
