Abstract: A method of augmenting the number of labeled images for training a neural network comprising the steps of—Starting from a dataset of labeled images with corresponding segmentation masks and a dataset of unlabeled images, gathering for a given image i in a data set of labeled images a number of images with similar metadata in said dataset of unlabeled images so as to form data sub-set Sim i,—Training a multiclass segmentation neural network on said labeled images thereby generating segmentation masks for the images in subset Sim i,—On the basis of these segmentation masks judging similarity between images of Sim i and image i and finding the most similar image(s) in Sim i by computing and comparing histograms of segmentation masks of image i and images in Sim i—Transferring the histogram of the most similar images in Sim i to given image i.

Abstract: A neural network, trained for the task of deriving the attribution of image regions that significantly influence classification in a tool for pathology classification, comprising (i) a contracting branch, (ii) an attenuation module, (iii) an interconnected upsampling branch, and (iv) a final mapping module.

Abstract: A method for finding image regions that significantly influence classification in a tool for pathology classification in a medical image wherein image regions that influence classification are inpainted, by replacing the pixels in these regions by representations of heathy tissue, resulting in an image with a healthy classification-score in the classification tool.

Abstract: Kits and compositions for producing an alginate gel are disclosed. The kits and compositions comprise soluble alginate and insoluble alginate/gelling ion particles. Methods for dispensing a self-gelling alginate dispersion are disclosed. The methods comprise forming a dispersion of insoluble alginate/gelling ion particles in a solution containing soluble alginate, and dispensing the dispersion whereby the dispersion forms an alginate gel matrix. The methods may include dispensing the dispersion into the body of an individual. An alginate gel having a thickness of greater than 5 mm and a homogenous alginate matrix network and homogenous alginate gels free of one or more of: sulfates citrates, phosphates, lactatates, EDTA or lipids are disclosed. Implantable devices comprising a homogenous alginate gel coating are disclosed. Methods of improving the viability of pancreatic islets, or other cellular aggregates or tissue, following isolation and during storage and transport are disclosed.
