How Computer Vision Cut Image Processing Time by 99%
A Computer Vision model automated vehicle image verification, reduced manual review, and improved image processing efficiency.
At a Glance
Reviewing 120,000+ vehicle images each month and identifying irrelevant or inappropriate content was time-consuming. Maruti Techlabs built a Computer Vision model that automated image classification and vehicle verification, with human review for low-confidence cases.

The Client
The client is a US-based car trading platform that connects buyers and sellers through a nationwide network of 2,000+ buyers. Its platform facilitates instant vehicle quotes and handles nearly 1 million car sales annually.
The Challenges
Manual Image Reviews Slowed Vehicle Listing Operations
The platform received around 120,000 images every month, making manual verification time-consuming and error-prone. Irrelevant and inappropriate images could also affect customer experience and brand perception.
High Image Volumes Created Manual Work
A team of 15 agents manually reviewed large volumes of uploaded images every day.
Irrelevant Images Required Detection
Some uploads contained non-vehicle or inappropriate content instead of relevant car images.
Manual Reviews Increased Processing Time
Reviewing and classifying thousands of images created significant operational delays.
Errors Affected Customer Experience
Incorrectly approved images could reduce listing quality and negatively impact the platform's brand image.
Automate Image Verification With Computer Vision
Reduce manual image reviews while maintaining human oversight for uncertain cases.
The Solution
Automating Image Verification With Computer Vision
Maruti Techlabs built a custom Computer Vision model to automate two stages of the image verification process. The model classified vehicle images, identified potential issues, and verified whether the vehicle matched the details the seller submitted.
The solution classified images as car or non-car and flagged irrelevant uploads. It also identified objects blocking the vehicle and tagged images for further review.

The Journey
Data to Production
Business Outcomes
Faster Processing With Smarter Image Verification
99% Reduction in Processing Time
Automated image classification significantly reduced the time required to process uploaded images.
2,500 Hours Saved Monthly
Automation reduced the manual effort required to review and classify high volumes of images.
$700K Saved Annually
Lower manual processing requirements generated substantial annual operational savings.
90% Model Accuracy
Continuous supervised learning and model improvements increased accuracy from 85% at production deployment to 90% within six months.
Human Review for Uncertain Cases
Slack-based escalation allowed agents to review images when the model's confidence fell below 80%.
Continuous Model Improvement
Human classifications created a feedback loop that supported ongoing model learning and performance improvements.
Conclusion
The Computer Vision model reduced manual image processing while preserving human oversight for cases requiring additional judgment.

Frequently Asked Questions
The model used a confidence threshold to determine when its prediction required additional validation. Images with a confidence score below 80% were escalated to human agents through Slack. This allowed the system to automate high-confidence cases while reserving human effort for uncertain inputs.
The model was trained using car make and model recognition data. After identifying a vehicle image, it compared the detected make and model with the information the seller submitted. A mismatch triggered a flag for further review.
A fully automated model can encounter images that differ from its training data or contain ambiguous visual information. Human review provided a controlled fallback for low-confidence predictions and generated feedback to improve the model.
Human classifications can become additional training data for future model updates. In this case, feedback from reviewed images created a continuous learning loop that supported supervised learning and increased model accuracy from 85% to 90% over six months.
Teams should first define classification rules, build reliable training data, set acceptable confidence thresholds, and identify cases that require human intervention. Monitoring model accuracy after deployment is also important to ensure that automation continues to meet business requirements.
Yes. In this case, the model went beyond basic image classification. It also supported obstacle detection, image tagging, and vehicle make-and-model verification against seller-provided information.
