Application of Wavelet Transform in Image Processing in Aviation Engine Damage

Abstract

For the poor quality of the damage image which is obtained by techniques of practical endoscope detection, the damage image is not easy to identify, this article uses the wavelet transform method for processing damage image, adopts soft threshold method to filter the noise, and then enhances the image, finally employs wavelet transform method in the image edge detection, protrudes the information of the fault and the edge, which is convenient for damage recognition.
