Measuring heat exchange processes at the air-water interface from thermographic image sequence analysis
… flux is presented. These techniques are based on thermal image sequences on which a motion analysis is performed. The motion is modelled in a general parameterization and physically motivated intensity changes can be incorporated by means of linear partial differential equations. In the presented …

Methods for multi-spectral image fusion: identifying stable and repeatable information across the visible and infrared spectra
Fusion of images captured from different viewpoints is a well-known challenge in computer vision with many established approaches and applications; however, if the observations are captured by sensors also separated by wavelength, this challenge is compounded significantly. This dissertation …

Determining the Oncological and Immunological Effects of Histotripsy for Tumor Ablation
Histotripsy is an emerging non-invasive, non-thermal, image-guided cancer ablation modality that has recently been approved for its first clinical trial in the United States (NCT04573881). Histotripsy utilizes focused ultrasound to generate acoustic cavitation within a tumor to mechanically …

Novel solid state modulator for the infrared: the germanium chopper
Uncooled thermal imaging cameras in the 8 to 14 µm band use pyroelectric array detectors as the preferred technology. The systems advantages offered by these uncooled detectors are those of reduced cost, complexity and power consumption. The price paid for this uncooled technology is that the image …
