We propose radial harmonic Fourier moments, which are shifting, scaling, rotation, and intensity invariant. Compared with Chebyshev-Fourier moments, the new moments have superior performance near the origin and better ability to describe small images in terms of image-reconstruction errors and noise sensitivity. A multidistortion-invariant(More)
We present a new method to register high and low resolution color images of the retina as well as high resolution angiographies. The registration method is based on global point mapping with blood vessel bifurcations as control points. We also present results of various image fusion algorithms to determine the most appropriate one. Registration and fusion(More)
Cell mechanical activity generated from the interplay between the extracellular matrix (ECM) and the actin cytoskeleton is essential for the regulation of cell adhesion, spreading and migration during normal and cancer development. Keratins are the intermediate filament (IF) proteins of epithelial cells, expressed as pairs in a lineage/differentiation(More)
In this paper, we apply a recently developed type of moments , Orthogonal Fourier-Mellin Moments (OFMMs) [7], to the specijic problem of fully translation-, scale-and in-plane rotation-invariant detection of human faces in two-dimensional static color images, and we compare theirper-formance with that of the generalized Hu's moments or non-orthogonal(More)
