Image-processing-based model for surface roughness evaluation in titanium based alloys using dual tree complex wavelet transform and radial basis function neural networks

In this study, we examine the assessment of surface roughness on turned surfaces of Ti 6Al 4V using a computer vision system. We utilize the Dual-Tree Complex Wavelet Transform (DTCWT) to break down ...

Image denoising in acoustic microscopy using block-matching and 4D filter

In materials science to biology, scanning acoustic microscopes (SAM) have been successfully used to image the surface and interior structures and conduct nondestructive evaluations without causing ...
