1. Change Detection of the Unexpected : Enhancing change detection of the unexpected in a complex and high risk context – guiding visual attention in a digital display environment
Sammanfattning : Change detection of objects and events in our visual surroundings is sometimes severely difficult, especially if these changes are unexpected. Such failures in change detection may cause huge malicious outcomes in contexts characterized by high levels of complexity and risk. LÄS MER
2. Change Detection Using Multitemporal SAR Images
Sammanfattning : Multitemporal SAR images have been used successfully for the detection of different types of environmental changes. The detection of urban change using SAR images is complicated due to the special characteristics of SAR images—for example, the existence of speckle and the complex mixture of the urban environment.

3. Urban Change Detection Using Multitemporal SAR Images
Sammanfattning : Multitemporal SAR images have been increasingly used for the detection of different types of environmental changes. The detection of urban changes using SAR images is complicated due to the complex mixture of the urban environment and the special characteristics of SAR images, for example, the existence of speckle.

4. Landscape from space : geographical aspects on scale, regionalization and change detection
Sammanfattning : Landscapes are complex systems composed of multiscale hierarchically organized entities that interact within unique spatial and temporal scales. These interactions result in scaledependent spatial patterns that visually change depending upon the scale at which they are observed. LÄS MER
5. Novelty and change detection radiation physics experiments
Sammanfattning : This thesis deals with the detection and analysis of low-level natural and induced radioactivity. Using high energy-resolution Ge detectors in low-level counting areas airborne radioactivity’s like Be-7 and Cs-137 have been investigated. The experimental facilities and techniques are described in some detail. LÄS MER
