3D Object Detection and Tracking

Vision sensor data (RGB and Depth) collected from a semi-humanoid robot ‘Pepper’ provided by IATSL laboratory, are used to perform 3D human detection and tracking within a household setup enabling better assistance to old or sick-adults in home-care.

Feature Detection and Matching

This project implements feature point detection and its matching between stereo pair images from KITTI dataset. For a given input RGB image from left camera, the features which are described to be an image region that is salient, local, repeatable, compact and efficient, are identified and studied by visual inspection for unreliability on matching.

IDC type Breast Cancer Classification

Breast cancer classification on Keras (based on the implementaion of CancerNet algorithm by Adrian Rosebrock [1]). Breast cancer is the most common form of cancer in women, and Invasive Ductal Carcinoma (IDC) is the most common form of breast cancer.

Lidar and IMU calibration
