Abstract
We have developed welding support system based on the cases consisting of welding beads image, welding condition, evaluation results and notes. This paper discusses an extraction of image features from welding beads, which indicate technique of well-skilled welders. We examine two type of features such as Speeded Up Robust Features (SURF) and Gray-Level Co-Occurrence Matrix (GLCM). We have tried to use these features and examined the features can be applied to for the beginners to obtain welding technique.
