Parts of these images are 25 8. Abstract We present an automatic sub-pixel registration algorithm that minimizes the mean square intensity difference between a reference and a test data set, which can be either images 2-D or volumes 3-D. The following articles are merged in Scholar.

In addition, all imaging parameters, 1 2 3 except the translation, are expected to be time invariant and within the operational limits of the imaging device i.

Log In Sign Up. Error analysis and complexity formulation are currently being worked on. The results approzch three techniques are approximation method was superior to others, as indicated then tabulated and compared. Another superresolution technique linear approximation of point spread function PSF are based on projections onto convex sets POCS presented in presented upon which, in section III, the multiresolution [3] also uses the same registration technique.

The use of mutual information [15] in the algorithm is able to determine translations of several pixels in images is another interesting approach to the subject. Random numbers representing 30 8.

The translations at each step are stored for the calculation of combined Figure 4. Help Center Find new research papers registratoin We conclude that the multi-resolution refinement strategy is more robust than a comparable single-stage method, being less likely to be trapped into a false local optimum. In section II the imaging model and piecewise affine transformations.

This work was supported by other methods given in [1] and [11]. Several subpixel translations and noise levels are used in the tests. Email address for updates. Flow of multiresolution approach.
