Semantic Segmentation using Dictionary Learning [Report] [Code]

We study the pipepline of semantic segmentation using dictionary learning. The algorithm is applied on MRI image for Multiple Sclerosis segmentation and aerial images for building segmentation. The empirical results show that preprocessing is substantially important for the pipeline and the performance can be bounded with improper preprocessing.

Uncalibrated Visual Servoing

We study uncalibrated visual servoing using a 4-DOF robotic arm: Barrett WAM. The target is specified on the images which is then directly used for inverse kinematics.
