Personal project · Computer vision

Custom Climbing Grip Trainer

End-to-end pipeline that measures hand proportions from a single photo and generates a custom-fit ergonomic grip trainer.

  • RF-DETR and SAM2 for object detection and segmentation
  • Custom heatmap-based keypoint detector to locate finger creases
  • Parametric CAD model generated to the measured hand geometry
  • Self-validation checks and interactive feedback guide users toward a good photo and flag bad inputs

Local Cluster Cardinality Estimation for Adaptive Mean Shift

Research article on the adaptive mean shift algorithm based on distance distribution analysis, from my PhD studies.

  • Development of a local cluster cardinality estimator based on distance distributions
  • Adaptive mean shift driven by the local cardinality estimator
  • Mathematical proofs on distance distributions

Keypoint Masking for Analyzing Segmented Medical Image Data

Analysis of keypoint extraction on masked images, resulting in an extraction procedure that limits masking-related noise.

  • Supported by a theoretical model valid for images of any dimension
  • Applied to 3D medical images
  • Open-source Python implementation

Climbing Grade Analysis

Analysis of difficulty range within Fontainebleau climbing grades: some grades contain twice the difficulty range, leading to an uneven grade progression for climbers.

  • Database manipulation with Pandas
  • Original data analysis leading to new insight
