Computer vision / image processing / machine learning / algorithms.
More than 9yrs of experience working on software research and development. Co-founded a tech startup, 2+yrs as a full-time freelancer.
Computer vision topics I've worked on: background subtraction, binary segmentation, facial expression transfer using active appearance models, object recognition, image restoration, projective geometry correction, object tracking, video stabilization, graphs cuts, face authentication, OCR pre-processing, gesture recognition, etc.
color: color quantization, color constancy (shadow removal), reduction to dominant color palette, illumination invariant color distance, color blending, color correction (gamut transform),
Learning topics: Classification: linear regression, LDA, SVM.
Clustering: KMeans, hierarchical kmeans, nearest neighbour.
Probabilitic analysis: naive bayes. Recommender systems.
Performance optimization: Speed up of background subtraction algorithms by writing optimized C code and SSE intrinsics.
