Advanced Image Analysis & Defect Identification

Image Comparison & Defect Detection System

We are looking to develop a solution capable of accurately detecting differences between two images.

Project Description:
We have:

An original PNG file
A scanned version of the same file after it has been printed

The goal is to compare these two images and:

Detect even the smallest differences
Identify print-related defects (shifts, distortions, color variations, etc.)
Perform detailed visual error analysis

Requirements:

High-precision or pixel-level comparison
Robust handling of scan noise and imperfections
Automatic image alignment (if needed)
Output results as highlighted differences and/or a report

Preferred Skills & Technologies:

Python (OpenCV, Pillow, or similar libraries)
Experience in Computer Vision and Image Processing
Prior experience with similar projects is a plus

Deliverables:

A working script or application
Sample outputs demonstrating detection results
Brief technical documentation
