" Segmentation is basically a process of pixel classification, the picture is segmented into subsets by assigning the individual pixel to classes. In this case when segmentation by thresholding it have to do classifying the pixels into " dark" and "light" classes, in an attempt to distinguish dark object from their light background. Similarly in edge detection pixels is classified into "edge" and "not edge" by thresholding the response of some difference operator that has high values ... "

N2 laser fluorescence spectrometer using boxcar integrator

" ABSTRACT
Observation of fluorescence decay signal of condensed-state molecular samples in the time domain has proved very useful for its identification and analysis. In order to overcome the noise problem in the generally weak fluorescence signals a double-gated boxcar integrator has been designed and incorporated into a spectrometer. The design concept and the working principle of this spectrometer is presented along with detailed description of its subsystems. Performance of this spectrometer has been tested with well-known ...
