...Partha Haldar; Alok Mukherjee; Tapas Kumar Bhattacharya; Nipu Modak The present research is emphasized on the microscopic observation of post-wear surface of nano-TiO 2 -doped alumina ceramics to access wearing by promising image processing algorithms, namely, entropy analysis, Sobel edge detection...

... developed in this study can be used to measure surface roughness reliably and precisely. A guide on how to determine the iris size, step size, and objective lens has been scientifically provided according to theoretical analysis and experimental results. optical microscopy image processing surface...

... characteristics. 4 Multiple image processing: (a) original image, (b) after median filtering, (c) after spatial filtering, (d) after ridgeline extraction, and (e) after straightening To suppress the noise effects and to extract the ridgeline accurately from the fringe pattern, multiple smoothing...
