Image Quality Audit Tool

A quality-control workflow for identifying collectible image crops that may need manual review.

Summary

This project supported quality control for cropped collectible images by flagging records that may have orientation issues, failed crops, or other visual problems before final review.

Problem

Large batches of cropped collectible images needed to be reviewed for issues such as incorrect orientation, flipped images, failed crops, or unreadable results. Manual review alone could be slow and inconsistent, especially when working with high-volume image sets.

Goal

Create a workflow that could help prioritize manual review by surfacing images most likely to need attention.

My Role

Contributed to the design and development of an audit approach that combined image-processing techniques, OCR, feature matching, and machine-learning-assisted flagging to identify crops that may require review.

Solution

The audit workflow analyzed cropped images with multiple checks instead of relying on a single method. OCR helped detect readable text and possible orientation issues. Feature matching helped compare expected visual structure. Image-processing and machine-learning-assisted checks helped flag suspicious crops for manual review.

Key Features

  • Batch scanning of cropped collectible images
  • OCR-based text/orientation checks
  • Feature matching against expected visual structure
  • Image quality checks for suspicious crops
  • Machine-learning-assisted flagging
  • Review queue for images needing attention
  • Flag categories such as possible flip, rotation needed, crop warning, or OCR mismatch

Technical Decisions

Why multiple detection methods were used

No single technique was reliable enough on its own, so the workflow combined OCR, feature matching, image-processing checks, and ML-assisted flagging.

Why the tool flagged for review instead of making final decisions

The goal was to support quality control and prioritize human review, not fully replace judgment in uncertain cases.

Why recreated mockups are used in the portfolio

The original work involved private/professional systems, so the portfolio uses recreated visuals and generalized descriptions without exposing proprietary data.

Impact

The tool supported the quality-control process by helping surface images most likely to contain crop, orientation, or visual-quality issues. This made review work easier to prioritize and helped improve consistency in the image audit workflow.

What I Learned

This project strengthened my understanding of image-processing workflows, quality-control automation, and how to combine multiple technical approaches to solve practical production problems.
