Detailed resume in pdf format.
In vascular exams with digital radiography, the interventions are carried out under limited radiation, producing relatively
noisy and low-contrasted images. The topic of my research is to make the temporal denoising filters robust to the motions in the images.
(More on the problem statement)
The major originality of these motion estimation and compensation tasks is to deal with transparent images. The PhD is structured in two
parts: the development of motion estimation techniques specific to transparent images, that are robust to noise, and the use of this
motion information to temporally denoise the clinical sequences.
(More on our contribitions, including some demos!)
Key words: object tracking, transparent images, multiple motions, denoising.
phD topic: Fluoroscopic noise reduction by filtering in the motions' direction.
