ImageClassification
I participated in an automated weapon detection research project that involved training Computer Vision models. My tasks included data collection, annotation, and preparing labeled imagery datasets for model development. I was involved in iterative model training and evaluation cycles for object recognition tasks. • Curated and labeled thousands of images for the purpose of detecting weapons. • Used classification labeling to help models distinguish between weapons and non-weapons. • Contributed to real-world dataset preparation, ensuring data diversity. • Supported model evaluation with manually-validated test sets.
