In this paper, we present a method for cup boundary detection from monocular colour fundus image to help quantify cup changes. The method is based on anatomical evidence such as vessel bends at cup boundary, considered relevant by glaucoma experts. Vessels are mod-eled and detected in a curvature space to better handle inter-image variations. Bends in a(More)
In this paper we report a newly developed technique - laser calorimetry spectroscopy (LCS), which is a combination of laser absorption spectroscopy and calorimetry - for the detection of gases dissolved in liquids. The technique involves determination of concentration of a dissolved gas by irradiating the liquid with light of a wavelength where the gas(More)
The task of detecting peri-papillary indicators associated with the glaucoma is challenging due to the high degree of intra-and inter-image variations commonly seen in colour retinal images. The existing approaches based on direct modeling of the region of interest fail to handle such image variations which compromises detection accuracy. In this paper, a(More)
