Progressive Frequency-Guided Depth Model with Adaptive Preprocessing for Casting Defect Detection

Yingbo Wang,
Fengyuan Zuo,
Shuai Zhang
et al.

Abstract: This article proposes a progressive frequency domain-guided depth model with adaptive preprocessing to solve the problem of defect detection with weak features based on X-ray images. In distinct intuitive surface defect detection tasks, non-destructive testing of castings using X-rays presents more complex and weak defect features, leading to lower accuracy and insufficient robustness on the part of current casting defect detection methods. To address these challenges, the proposed method establishes four spec… Show more
