The advancement of tools for tractography, image segmentation and coregistration (between subject normalization) and anatomical templates will help to improve anatomic specificity of DTI characterization in both clinical and research settings. Finally, new diffusion measurement techniques with MRI are being ...
The image tensor has been normalized so Matlotlib cannot display it correctly. TorchShow does the conversion automatically. 2. Visualizing Mask Tensors For projects related to Semantic Segmentation or Instance Segmentation, we often need to visualize mask tensors -- either ground truth annotations or...

To infer temporal dynamics within spatial transcriptomics, SpaceFlow18 uses proximity information to constrain the cell embedding and pseudotime ordering for spatial consistency. SIRV19 develops a spatially resolved RNA velocity approach, by improving estimation of unspliced and spliced mRNA using reference...
1. Different samples of the segmentation process for a gray level image belonging to the test set, using the compact and adaptive compact structure tensor (5% of variance), respectively, and KL distance The results, both for gray-level and colour images, show clearly that the tensor processing...
Context information plays an indispensable role in the success of semantic segmentation. Recently, non-local self-attention based methods are proved to be effective for context information collection. Since the desired context consists of spatial-wise an
