Motion estimation is a key problem in the analysis of image sequences. From a sequence of images we can only estimate an approximation of the image motion field called optical flow. We propose to improve optical flow estimation by including information from images of textural features. We compute the optical flow from intensity and textural images from(More)
Heterostructured thin films differing either in their structure, composition, or in both have shown novel magnetic, [1,2] super-conducting, [3] ferroelectric, or electromechanical [4,5] responses. In the case of ferroelectrics, multilayers or superlattices have displayed enhanced polarization, [5–7] high dielectric permittiv-ity [8,9] and in some instances,(More)
We investigate the interfacial chemistry of secondary Fe 2 O 3 phases formed in a BiFeO 3 (BFO) layer in BFO/ La 0.67 Sr 0.33 MnO 3 (LSMO)/SrTiO 3 (STO) heterostructures. A combination of high-resolution spherical aberration corrected scanning TEM and spectroscopy results, reveals that specific chemical and crystallographic similarities between Fe 2 O 3 and(More)
