Cobalt doped BaTiO<sub>3</sub> (BaTi<sub>1-x</sub>Co<sub>x</sub>O<sub>3</sub>) with x = 0, 5, 7.5, 10% have been synthesized by solid state reaction method and their structural, electrical and magnetic properties have been investigated. Structural characterization show that a multiphase ceramic containing both tetragonal and hexagonal structures are(More)
Capillary Non-Perfusion (CNP) is a condition in diabetic retinopathy where blood ceases to flow to certain parts of the retina, potentially leading to blindness. This paper presents a solution for automatically detecting and segmenting CNP regions from fundus fluorescein angiograms (FFAs). CNPs are modelled as valleys, and a novel multiresolution technique(More)
