High-Accuracy 3D Contour Measurement by Using the Quaternion Wavelet Transform Image Denoising Technique
In this paper, we propose an image denoising algorithm based on the quaternion wavelet transform (QWT) to address sinusoidal fringe images under strong noise in structured light 3D profilometry. The analysis of a quaternion wavelet shows that the amplitude image of the quaternion wavelet is easily a...
