Assessment of Thematic Mapper Band-to-band Registration by the Block Correlation Method

摘要: Rectangular blocks of pixels from one band image were statistically correlated against centered on identical a second image. The block pairs shifted in pixel increments both vertically and horizontally with respect to each other the correlation coefficient maximum was taken as best estimate registration error for pair. For combinations Arkansas scene studied, misregistration TM spectral bands within noncooled focal plane lie well 0.2 target specification. Misregistration between middle IR is this specification also. thermal has an apparent 7 approximately 3 direction. across-scan direction 0.5 along-scan direction, 5 7.
