An Adaptive Algorithm for Detection of Multiple-Type, Positively Stained Nuclei in IHC images with minimal Prior Information: Application to OLIG2 Staining Gliomas
(Spie-Int Soc Optical Engineering, 2015)We propose a method to detect and segment the oligodendrocytes and gliomas in OLIG2 immunoperoxidase stained tissue sections. Segmentation of cell nuclei is essential for automatic, fast, accurate and consistent analysis ... -
Automated detection of cells from immunohistochemically-stained tissues: Application to Ki-67 nuclei staining
(Spie-Int Soc Optical Engineering, 2012)An automated cell nuclei detection algorithm is described to be used for the quantification of immunohistochemically-stained tissues. Detection and segmentation of positively stained cells and their separation from the ... -
Gibbs Free Energy Assisted Passivation Layers
(Spie-Int Soc Optical Engineering, 2016)Reduction of surface leakage is a major challenge in most photodetectors that requires the elimination of surface oxides on etched mesas during passivation. Engineering the passivation requires close attention to chemical ... -
High quantum efficiency Type-II superlattice N-structure photodetectors with thin intrinsic layers
(Spie-Int Soc Optical Engineering, 2013)We report on the development of InAs/AlSb/GaSb based N-structure superlattice pin photodiode. In this new design, AlSb layer in between InAs and GaSb layers acts as an electron barrier that pushes electron and hole wave ... -
IFVD-based large intermixing selectivity window process for high power laser diodes
(Spie-Int Soc Optical Engineering, 2018)Catastrophic optical mirror damage (COMD) is a key issue in semiconductor lasers and it is initiated by facet heating because of optical absorption. To reduce optical absorption, the most promising method is to form ... -
Low dark current N structure superlattice MWIR photodetectors
(Spie-Int Soc Optical Engineering, 2014)Commercially available read out integrated circuits (ROICs) require the FPA to have high dynamic resistance area product at zero bias (R(0)A) which is directly related to dark current of the detector. Dark current arises ... -
Trend of Normalized Difference Vegetation Index (NDVI) over Turkey
(Spie-Int Soc Optical Engineering, 2018)Ecosystem productivity, biome distribution, and forest carbon stocks are likely to be changed by the climate change. These ecosystems changes can be identified using Satellite based normalized difference vegetation index ...
