My main focus lies on improving the image quality by developing novel image and video resolution enhancement techniques (super-resolution, interpolation, regridding, demosaicing), and applying image and video restoration (denoising and deblurring). Specifically for video processing, I focus on real-time processing such as recursive upscaling up to 4K video content. In the past, I've also been working on video summarization (related keywords are: shot detection, hierarchical browsing, scene clustering and keyframe selection).
In medical imaging, I concentrate on compressed sensing applications (MRI reconstruction) and in bio-imaging, I work on restoration (denoising and deblurring) in several microscopy applications such as confocal fluorescence microscopy and 3D electron microscopy. I also performed (objective) image quality assessment in applications such as MRI reconstruction and compression of digital pathology images.
On the one hand, I have worked on extracting high-quality depth maps (focusing on denoising, super-resolution and sensor fusion) and on the other hand, I have worked on view synthesis (interpolation and inpainting). I also concentrate on SLAM/SFM technologies and point cloud processing for AR applications. The knowledge is applied in a wide variety of 3D/depth technologies such as Time-of-Flight, Kinect, microstereopsis, multi-camera arrays and LIDAR.
Beside restoration of hyperspectral data, I have worked on image registration and video mosaicing. Some special applications include registration of Synthetic Aperture Radar (SAR) images (main challenges: huge amount of data and the presence of speckle noise) and video mosaicing for benthic habitat mapping (main challenges: non-uniform illumination and moving benthic fauna).
Last but not least, I have been working on improving the OCR rate (optical character recognition) of low-resolution digital documents using non-local strategies.
I am co-lecturer of the course estimation and decision techniques:
I received the B.Sc and M.Sc degrees in computer science engineering (option Telecommunication) from Ghent University , Belgium, in 2001 and 2003 respectively.
In 2009, I received the Ph.D degree in computer science engineering at Ghent University under the supervision of prof. dr. ir. Wilfried Philips .
I was born in Sint-Niklaas, Belgium on July 24, 1980.
