Vision Mark

Smart Vision. Seamless Attendance

Comment

Inspiration

Traditional attendance systems are time-consuming, error-prone, and easy to manipulate. Manual roll calls interrupt classes, proxy attendance undermines integrity, and biometric systems often require expensive hardware. We were inspired to solve this problem using computer vision and automation, creating a system that is fast, contactless, and scalable. VisionMark was born from the idea that a camera and intelligent AI are enough to reliably verify presence.

What it does

VisionMark is an AI-powered automatic attendance system that uses computer vision to identify individuals and mark attendance in real time.

The system:

Detects faces from live camera feeds or images

Recognizes registered individuals using face embeddings

Automatically marks attendance without manual intervention

Teacher Also Mark Attendence Manually

Teacher And Student Login Page

Stores attendance records digitally for accuracy and traceability

VisionMark eliminates proxy attendance, reduces administrative overhead, and provides a seamless, contactless attendance experience.

How we built it

VisionMark was built using a modular AI pipeline:

Face Detection We used a computer vision model to detect multiple faces in real time from camera input.

Face Recognition Each detected face is converted into embeddings and compared with stored encodings to identify individuals accurately.

Attendance Logic Once a match is confirmed, attendance is marked automatically while preventing duplicate entries.

Data Storage Attendance data is stored securely in structured formats (CSV / database) for easy access and reporting.

User Interface A simple interface allows administrators to register users, capture images, and review attendance logs.

The system is designed to be lightweight, hardware-independent, and deployable in classrooms or offices.

Challenges we ran into

Lighting and Angle Variations: Face recognition accuracy can drop under poor lighting or extreme angles.

Multiple Faces in a Frame: Handling simultaneous detection and recognition while maintaining performance required careful optimization.

False Positives & Negatives: Balancing strictness and flexibility in recognition thresholds was critical.

Real-Time Performance: Ensuring smooth processing without lag on standard hardware was a significant challenge.

Accomplishments that we're proud of

What's next for Vision Mark

We plan to enhance VisionMark with:

Liveness detection to prevent spoofing using photos or videos

Cloud-based dashboards for analytics and reporting

Mobile and web app integration

Role-based access control for administrators and instructors

Improved model training for higher accuracy across diverse environments

Our long-term goal is to make VisionMark a secure, intelligent, and widely deployable attendance solution for educational institutions and organizations.
