Wavelet Transform based Recognition of Machined Surfaces using Computer Vision

摘要

This paper presents wavelet based recognition of the machined surfaces namely turned, ground and shaped surfaces from the images acquired using Computer Vision System. Selection of mother wavelet has been done based on the peak signal to noise ratio (PSNR) value using Discrete Wavelet Transform (DWT) which has been used for feature extraction. Artificial Neural Network (ANN) has been used to recognize the machined surfaces.
