1. Visual Attention in Active Vision Systems : Attending, Classifying and Manipulating Objects
Abstract : This thesis has presented a computational model for the combination of bottom-up and top-down attentional mechanisms. Furthermore, the use for this model has been demonstrated in a variety of applications of machine and robotic vision. READ MORE

2. Peripheral Vision : Adaptive Optics and Psychophysics
Abstract : This thesis is about our peripheral vision. Peripheral vision is poor compared to central vision, due to both neural and optical factors. The optical factors include astigmatism, defocus and higher order aberrations consisting mainly of coma. Neurally, the density of ganglion cells decreases towards the periphery, which limits the sampling density. READ MORE

3. Computational Methods for Computer Vision : Minimal Solvers and Convex Relaxations
Abstract : Robust fitting of geometric models is a core problem in computer vision. The most common approach is to use a hypothesize-and-test framework, such as RANSAC. In these frameworks the model is estimated from as few measurements as possible, which minimizes the risk of selecting corrupted measurements. READ MORE

4. Camera Modelling and Calibration for Machine Vision Applications
Abstract : This thesis describes camera based methods for determining positions and orientations of objects in 3D-space. These methods are useful in several applications where camera images are used for acquiring information about the surroundings, and the targeted application here is guiding robots using a camera mounted on the robot hand.

5. Embedded high-resolution stereo-vision of high frame-rate and low latency through FPGA-acceleration
Abstract : Autonomous agents rely on information from the surrounding environment to act upon. In the array of sensors available, the image sensor is perhaps the most versatile, allowing for detection of colour, size, shape, and depth. For the latter, in a dynamic environment, assuming no a priori knowledge, stereo vision is a commonly adopted technique. READ MORE
