- The accuracy of the algorithm was found to vary in proportion to sigma/n(1 - delta)(2), where sigma is the speckle size, n is the subimage size, and delta is the amount of decorrelation, with negligible systematic errors. For typical values the uncertainty in the displacement is approximately 0.05 pixels.

- The speckle size has a decisive effect in DSP accuracy. First of all, the range of measurable displacement in DSP is limited by the decorrelation of speckle patterns to several tens of pixel size [18]. Besides, the speckle size should be greater than 2 pixels to satisfy the Nyquist sampling criterion.
