DIGITAL IMAGE REGISTRATION AND MOSAICING FOR REMOTE SENSING
T Wang · Chinese Journal of Computers · 1985
This paper deals with digital image registration and mosaicing on the interactive image processing system as I2S 101. There are two interactive steps to be taken in accomplishing the digital image, registration and mosaicing work. Step one is to pick up the control point set which determines the geometric position of images, and then to derive a geometric transform for registering one image to another from those points. The geometric transform may be affine or nonlinear. Step two is to determine the parameters of brightness transform from histogram or other statistical value. Generally, brightness transform is piecewise linear mapping. Th final part provides the reader with some practical problems for further research.
