The surface defect dataset released by Northeastern University (NEU) collects six typical surface defects of hot-rolled steel strips, namely rolling scale (RS), plaque (Pa), cracking (Cr), pitting surface (PS), inclusions (In) and scratches (Sc).
Then, apply the nail polish in a thin layer over the scratch. Clean off any excess before it dries. Once it has dried, you should see a difference in the scratch depth. 3. Toothpaste. Another option for minor scratches is a non-gel toothpaste. The paste is capable of gently removing the glass around the scratch to make a flat, clean surface.

This paper presents an automatic flaw inspection scheme for online real-time detection of the defects on the surface of lithium-ion battery electrode (LIBE) in actual industrial production. Firstly, based on the conventional methods of region extraction, ROI (region of LIBE) could be extracted from the captured LIBE original image. Secondly, in order to reduce the influences of uneven ...
All my surface scratches were made by 2500 grit sandpaper. (wet sanded, not dry) This is considered a VERY minimal scratch depth. The first phot is the before. The second is after 1 hour of hand rubbing until my latex gloves tore. Than I tried attaching the (magic cloth) to battery operated drill and went in circular motion with mild pressure.
Clear coat scratches merely mar the surface, while primer-level scratches are more serious, and deep paint scratches are the most severe, penetrating through to the paint layer. Identifying the type of scratch is pivotal in determining the appropriate repair method.
The pit on the bottom metal surface is one of the important indicators of cylindrical lithium battery surface defect detection. There are many complex factors in the detection of pit: non-uniform illumination of images, uneven reflection of the metal surface, low surface finishing, stains, rust and scratches. To solve these problems, a method for pit detection based on machine vision is ...
