Abstract :
Considers the development and evaluation of real-time image processing algorithms capable of measuring, to sub-pixel accuracy, the displacement between images subjected to simultaneous translation and rotation. The techniques could have a number of applications, for example, in stabilising imagery recorded from vibrating platforms or in the data compression of moving imagery. The following classes of algorithm were investigated: phase correlation algorithms (both 2-dimensional and 1-dimensional); and intensity gradient based algorithms
