Smartphone screen surface defect annotation

This 200 image-sized dataset contains 20 Megapixel photos of smartphone device front screen surfaces.

The goal is to highlight all areas that contain defects which may include: scratches, pit-defects, blemishes, missing surfaces, cracks, discolored areas, etc.

It is also important that the annotated area should include all the defected image pixels and exclude background pixels as much as possible.

Pre-annotations are provided.
