Introduction Magnetic Resonance Spectroscopic Imaging (MRSI) is a powerful technique to gain insight into physiological processes in the human body. Since 2D MRSI examinations typically last excessively long, the use of acceleration techniques is of great importance. Here, we use a SENSE approach [1, 2, 3]. The Spatial Response Function (SRF) indicates which spatial areas contribute to the fina...

In this paper, we present a spatially adaptive method to reduce compression artifacts observed in block discrete cosine transform (DCT) based image/video compression standards. The method is based on the bilateral filter, which is very effective in denoising images without smoothing edges. When applied to reduce compression artifacts, the parameters of the bilateral filter should be chosen care...

In our contribution, we compute new edge wavelet filters for image compression and we compare errors for several image compression techniques. Our numerical experiments confirm the theoretical assumption that the error of the compression is smaller for the discrete wavelet transform with derived edge filters than for other methods using an extension of an image.
