All-fiber optic integration type of weld seam image sensing system

This article carries out feature analysis and summary of V sharp weld seam image collected by structural-light,and proposals different image processing methods aiming at different feature,on basis of which,weld seam image process is completed by means of global threshold segmentation and morphology filter determined by automatic threshold,and obtain excellent effect of image processing.

Defect extraction in weld image based on Generalized Fuzzy Operator;

Some filter methods were analyzed to find the characteristics of the weld image noises.

Improved OTSU method on welding seam image segmentation;

However, because welding seam images are complicated, it is very important to choose suitable and effective processing algorithm in order to get accurately the information.

The wavelet edge detecting method was introduced to the welding seam image processing in this paper,which can make up the defect of usual edge detecting methods in antinoise ability and precise locating ability.

Research on Underwater Image Pre-Processing Based on Entropy and Recognition of Underwater Object;

A new method for underwater image enhancement based on local complexity

For the underwater image of swimming pool, its S/N is low and the edge is fuzzy.
