SELECTED PROJECTS

Slot Style Classifier

Computer Vision | Unsupervised Learning

● Developed a computer vision pipeline to analyze slot games using both static screenshots and gameplay videos.
● Extracted spatial and temporal features with OpenCV and applied unsupervised learning (K-Means) to discover
gameplay patterns.
● Compared static image classification with dynamic video analysis and demonstrated the limitations of single-frame
approaches.
● Built data preprocessing, feature extraction, visualization, and clustering pipelines using Python and Scikit-learn.
Technologies: Python, OpenCV, NumPy, Pandas, Scikit-learn, SciPy, Matplotlib

ErgoVision AI

Computer Vision | Pose Estimation | Video Analytics

● Developed a computer vision pipeline to analyze long videos using MediaPipe pose and face landmarks.
● Extracted posture and facial activity features, aggregated measurements over time, and detected unusual events
using z-score anomaly detection.
● Automated the generation of ranked video clips and reports, reducing manual review of 90-minute recordings to a
small set of relevant segments.
● Built an end-to-end pipeline including feature extraction, temporal aggregation, anomaly detection, visualization,
and FFmpeg-based video export.
