Interferometers with low-coherence illumination allow noncontact measurement of rough-surface relief with a wide range of measurement definition by locating the visibility maxima of interference fringes. The problem is light scattering by the surface to be measured, which can cause distortion of low-coherence interferometric signals. We propose to use a(More)
System for estimating the motion of independently moving objects observed by a moving camera is presented. It consists of feature matching and multi-body motion estimating modules. Novel set of invariant features is proposed on the base of phase spectrum differentiation without information loss. Clustering the feature points and estimating the(More)
Recovery of an unwrapped wavefront in phase-shifting interferometry is considered when the wavefront phase increments are determined between previous and subsequent fringe patterns as well as between adjacent pixels of the current fringe pattern. A parametric model of a three-dimensional interferometric signal and the recurrence processing algorithm in(More)
Investigation of images representations in Optical Coherence Tomography (OCT) is carried out based on the objective quality criterion introduced with the use of the novel representational minimum description length principle. Several image segmentation algorithms are proposed that recover layered structure of the OCT images and can be used for morphological(More)
