malleable cast iron surface defect dataset(MCISD)

To encourage research in computer vision for the railway, we present Rail-5k: a real-world image dataset for object detection of defects and accessories on the rail, along with methods for shooting, fine-frained category definition, and instance-level annotation.
We collected 5,000 high-quality RGB images from high-speed railway and subway across China, where each image with resolution as high as 0.03mm per pixel.
We annotate 1100 images with 13 types of defects and accessories that are the most important to rail maintenance such as rail surface, wheel-rail contact band, crack, spalling, corrugation, fastening, screw.
The dataset is superior to existing datasets in image quantity, resolution, annotation quality, dense and small objects.
It also contains real-world corrupted images with dark, overexposure, blur, other tools, different lens distance, category transition, different screws, which are infeasible for non-experts to annotate and recognize.
As a pilot study of rail defect detection, we perform comprehensive experiments using SOTA models.
Our experiments demonstrate several challenges Rail-5k posed to both computer vision and railway engineering. Future versions of this dataset will include even more images, segmentation annotations as well as more channels.

A surface defect detection dataset created by Northeastern University (NEU) that covers six different types of surface defects.

Metallic surface defect detection is an essential and necessary process to control the qualities of industrial products. However, due to the limited data scale and defect categories, existing defect datasets are generally unavailable for the deployment of the detection model. To address this problem, we contribute a new dataset called GC10-DET for large-scale metallic surface defect detection. The GC10-DET dataset has great challenges on defect categories, image number, and data scale. Besides, traditional detection approaches are poor in both efficiency and accuracy for the complex real-world environment. Thus, we also propose a novel end-to-end defect detection network (EDDN) based on the Single Shot MultiBox Detector. The EDDN model can deal with defects with different scales. Furthermore, a hard negative mining method is designed to alleviate the problem of data imbalance, while some data augmentation methods are adopted to enrich the training data for the expensive data collection problem. Finally, the extensive experiments on two datasets demonstrate that the proposed method is robust and can meet accuracy requirements for metallic defect detection.
