Stamp Verification
Description
Explore our comprehensive Stamp Verification Dataset featuring 400 scanned invoice images with varying stamp shapes, colors, and orientations.
Description:
The dataset addresses the need for an automated system for stamp segmentation and verification, particularly for environments like insurance companies where a large volume of documents is processed daily. Stamps can vary in shape, color, quality, and orientation, making detection challenging. This dataset aids researchers in developing such systems.
