Jhacson Meza

I received my B.S. and M.S. degrees from Universidad Tecnológica de Bolívar (Colombia) under the supervision of Prof. Andrés Marrugo and Prof. Lenny Romero working at OPI-Lab. My master's research was focused on developing a low-cost 3D multimodal imaging system for internal (with freehand ultrasound) and external (with structured light) 3D reconstruction. My undergraduate research involved using Structure-from-Motion for terrain 3D reconstruction for civil engineering applications.

At OPI-Lab I also worked on a robust, real-time marker-based 6D pose estimation method using neural networks for sub-pixel keypoint detection. Also, I was involved on cell segmentation, generating synthetic microscopy images using generative models for data augmentation.

My research interests include Computer Vision, 3D Imaging, Deep Learning, Machine Learning, Image Processing, Medical Imaging, and Optical Metrology.
