1. Spatial Vision in Bees : Behavioural investigation of spatial resolution and contrast sensitivity
Abstract : Bees use multiple sensory modalities to perform day-to-day tasks. Light allows them to perceive objects and the general features of their surroundings, enabling them to find food and to navigate safely across the landscape. READ MORE

2. The Role of Projected Anatomy, Random Noise, and Spatial Resolution on Clinical Image Quality in Digital Mammography
Abstract : Due to the recent advances in digital detector technology, there is an increasing trend in the use of digital mammography (DM) as a concurrent modality with screen-film mammography (SFM). In order to fully realize its potential, the components of a DM system should be optimized with respect to clinical image quality in order for clinicians to make accurate diagnoses. READ MORE

3. Forest planning utilizing high spatial resolution data
Abstract : This thesis presents planning approaches adapted for high spatial resolution data from remote sensing and evaluate whether such approaches can enhance the provision of ecosystem services from forests. The presented methods are compared with conventional, stand-level methods. READ MORE

4. Spatial vision in diverse invertebrates
Abstract : Light-detection provides incomparabaly rapid information at a range of time scales and, consequently, directional photoreception is found in almost every major metazoan clade. Conversely, a much smaller cohort have evolved sophisticated high resolution vision, which facillitates complex tasks via the detection of fast or small objects,. READ MORE

5. Novel computational methods for image analysis and quantification using position sensitive radiation detectors
Abstract : The major advantage of position sensitive radiation detector systems lies in their ability to non invasively map the regional distribution of the emitted radiation in real-time. Three of such detector systems were studied in this thesis, gamma-cameras, positron cameras and CMOS image sensors. READ MORE
