A number of image processing and computer vision tasks make use of a structure tensor based on Gaussian smoothing, or—equivalently—linear diffusion. Unfortunately, linear diffusion is well-known to destroy important structures such as discontinuities, while other structures may be dislocated. To addre...
We present a novel structure tensor for matrix-valued images. It allows for user defined parameters that add flexibility to a number of image processing algorithms for the segmentation and smoothing of tensor fields. We provide a thorough theoretical derivation of the new structure tensor, including...
The FTIR spectra were analysed on a Bruker Tensor II infrared spectrometer using KBr pellets. The electron paramagnetic resonance was conducted on an ELEXSYS-II, Bruker, whereas XPS was recorded on a Thermo Electron ESCALAB250 XPS spectrometer (X-ray source: Al). The carbon 1s line at 284.6...
Image analysis MRI diffusion tensor estimation Each DW image was up-sampled by a factor of 2 using trilinear interpolation to reach a voxel size of 0.3 × 0.3 × 0.3 mm3. Diffusion tensor calculations were performed prior to any registration to avoid difficult transformations of the ...

3.4 Texture and structure aware filtering network Network design Once the structure and texture guidance are generated, the texture and structure aware filtering network (TSAFN) concatenates them with the input to form a 5-channel tensor. TSAFN consists of 4 layers. We set a relatively large ...
1.1. A novel dense descriptor based on structure tensor voting Structure tensor represents the magnitude and orientation information of the edges of an image.20 Though the magnitude of the edges can be changed because of contrast variation, the orientation remains the same if the illumination or co...
where Cijkl is the elastic tensor as given in Section 3.4, and its symmetry has been used to derive Eq. (12.148b). The total strain energy of the elastic body is given by (12.148c)Π(q)=∫ΩsedΩ=12qTkq=12q˜TKq˜,q˜=[U0TθTqT]T,K=[00000000k],k=∫ΩsΦi,jTCijklΦ...
