— This paper presents a 6 degrees of freedom ego-motion estimation method using Iterative Closest Point (ICP) for low cost and low accuracy range cameras such as the Microsoft Kinect. Instead of Euclidean coordinates, the method uses inverse depth coordinates which better conforms to the error characteristics of raw sensor data. Novel inverse depth(More)
Technological intelligence is a highly sought after commodity even in traffic-based systems. These intelligent systems do not only help in traffic monitoring but also in commuter safety, law enforcement and commercial applications. In this paper, a license plate localization and recognition system for vehicles in Malaysia is proposed. This system is(More)
Different image processing approaches are presented that are candidates for the Monash Vision Group prosthetic vision device. As described in a companion paper [6], the Monash Vision Group is developing a bionic eye based on the implantation of 7-11 stimulation tiles on the primary visual cortex of the brain. In the lead up to an expected 2014 first inhuman(More)
Currently, most implanted visual prosthetic systems generate vision by translating sensor data from a headworn camera into electrical stimulation of the human vision system. Unfortunately , the resulting bionic vision has low spatial resolution and limited dynamic range. This dramatically reduces the usefulness of bionic vision in many real world scenarios.(More)
Loop closing is a vital component for mobile robot navigation without a priori information of the environment, since the mobile robot has to explore, build and at the same time maintain a globally consistent map. Moreover, it allows the mobile robot to recover from po-sitional drifts due to errors associated with sensor measurements once loop closing is(More)
Egomotion estimation is a fundamental building block for self-localisation and SLAM, especially when an accurate map is not available to the robot. This paper presents a real time plane-based approach to estimate the 6 degrees of freedom (DOF) pose of a moving Mi-crosoft Kinect. An inverse depth formulation is used to robustly fit multiple planes in the(More)
