Automated Visual Defect Classification for Flat Steel Surface: A Survey
Abstract
For a typical surface automated visual inspection (AVI) instrument of planar materials, defect classification is an indispensable part after defect detection, which acts as a crucial precondition for achieving the online quality inspection of end products. In the industrial environment of manufacturing flat steels, this task is awfully difficult due to diverse defect appearances, ambiguous intraclass, and interclass distances. This article attempts to present a focused but systematic review of the traditional and emerging automated computer-vision-based defect classification methods by investigating approximately 140 studies on three specific flat steel products of con-casting slabs, hot-rolled steel strips, and cold-rolled steel strips. According to the natural image processing procedure of defect recognition, the diverse approaches are grouped into five successive parts: image acquisition, image preprocessing, feature extraction, feature selection, and defect classifier. Recent literature has been reviewed from an industrial goal-oriented perspective to provide some guidelines for future studies and recommend suitable methods for boosting the surface quality inspection level of AVI instruments.
Overview

Written from the paper’s full text.
TL;DR
This survey reviews approximately 140 studies on automated visual defect classification for flat steel surfaces, covering continuous casting slabs, hot-rolled steel strips, and cold-rolled steel strips. It synthesizes traditional and deep-learning methods across five processing stages and identifies future directions such as multimode fusion, small-sample learning, and better time-cost evaluation.
Key findings
- The survey investigates approximately 140 studies and states that literature over the last ten years accounts for approximately 75% of the reviewed advancements.
- Methods are grouped into five successive components: image acquisition, image preprocessing, feature extraction, feature selection, and defect classifier.
- In feature selection, PCA is reported as the most frequently used dimension-reduction method, and GA is preferred for feature optimization; deep-learning methods such as CNN, CAE, and GAN are widely applied but often depend on labeled data.
- Table IV reports typical classification accuracies, including 99.50% for a deep CNN with majority voting on hot-rolled strips, 99.11% for generalized completed LBP + NNC on hot-rolled strips (266.74 ms per image), 97.5% for a SqueezeNet-based model (8.0 ms per image), and 98.12% for multiple support vector hypersphere with feature and sample weights (1.17 ms per image).
Methods
- Design: a focused systematic review of traditional and emerging computer-vision-based defect classification methods for flat steel, investigating approximately 140 studies on continuous casting slabs, hot-rolled steel strips, and cold-rolled steel strips.
- Organization: the review follows the natural image-processing procedure and groups approaches into image acquisition, image preprocessing, feature extraction, feature selection, and defect classifier.
- Analysis: it compares strengths and weaknesses of method families and includes a statistical list of typical methods with application, difficulty, performance, and classification time where available; no new experimental dataset is introduced.
Limitations
- Stated: most current classification methods emphasize accuracy and noise robustness while rarely involving time-cost evaluation, which matters for in-situ AVI on high-speed production lines.
- Stated: feature selection algorithms are generally identical and somewhat unitary in steel surface defect recognition, and the feature selection process is discounted; unsupervised learning results still show some disparity from the ultimate goal.
- Evident: as a survey, the paper reports no primary experiments, and many entries in Table IV have “T: NA,” limiting cross-study comparison of real-time suitability; its scope is also limited to three flat steel product types rather than all planar materials.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
A language model drew the claims from the paper on 2026-10-10, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-10-10 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
Cited sources are checked with a language model’s help (gpt-6-sol).
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
