Super resolution (SR) is the science of enhancing the
resolution of an image in a coherent way. Medical imaging (Radiography,
MRI, Ultrasound, Tomography ... ) is maybe the best customer of this
field of research since a higher spatial resolution makes the diagnosis
easier and more accurate. SR has been faced from the optical/acquisition
side and from the geometrical/post-processing side and in this talk we
are going to present a technique coming from the latter category. We
will exploit the multi-resolution features of the Wavelet transform to
adapt to the local characteristics of the image, then we will see how
Total Variation provides important local informations which will be used
to reconstruct the subpixel information that we were seeking.
Keywords: Super Resolution, Wavelet Transform, Total Variation, Medical
