Abstract :
The paper deals with a correlation method to estimate the amount of parallax of a short wave infrared radiometer which has a multi-spectral linear detector array assembly located on then focal plane. With equally spaced pre-resampled image data from the FFT method, a band to band corresponding point was found as a peak of the inner product of two image vectors of which the elements are the local pixel value. By applying the approach on actual JERS-1 SWIR (short wave infrared radiometer) images, the amount of parallax is evaluated with an accuracy of 0.136 pixels
