CdS films were deposited by CBD on a glass substrate by using CdI2 as a Cd+ source, thiourea as an S− source and NH4OH as the complexing agent. The effect of slow and rapid cooling on the films after thermal annealing was investigated in the present study. X-ray diffraction and Raman spectra of the films suggest that thermal annealing followed by slow cooling gives CdS with enhanced crystallinity...
Edge is the boundary between an object and the background, and identifies the boundary between overlapping and non-over lapping objects. This means that if the edges in an image can be identified accurately, all of the objects can be located and basic properties such as area, perimeter, and shape can be measured. Here fuzzy logic based image processing is used for accurate and noise free edge detection...
The Time Lapse Technique is cinematography technique where by each film frame is captured at much slower rate than it will replay back. When replayed at normal rate, time appears to be moving faster and thus time lapsing. Time lapse technique is very powerful technique to document slowly changing/ developing/ moving phenomenon. The natural movements like sunrise, blooming of flowers periodic time...
