The reason to shortlist U-Net was it is suitable on a small data set and also originally designed for Biomedical Image segmentation. Here, we propose a computationally efficient framework (SuperHistopath), designed to map global context features reflecting the rich tumor morphological heterogeneity. High computational cost associated with digital pathology image analysis approaches is a challenge towards their translation in routine pathology clinic. However, shapes, scales and appearance vary greatly from patient to patient, which pose a serious challenge to ... U-Net has achieved huge success in various medical image segmentation challenges. The KiTS19 challenge served to accelerate and measure the state of the art in the automatic semantic segmentation of kidneys and kidney tumors in contrast-enhanced CT imaging. Automatic semantic segmentation of kidney and tumor can be used to analyse the tumor morphology. As test data, participants will receive images without annotations for all tasks. Our team proposed a two-stage framework for kidney and tumor segmentation based on 3D fully convolutional network (FCN) and was ranked within top 4 performing ones. However, in kidney and kidney tumor segmentation additional challenges arise leading us to choose a different cost function. There is cur First, the number tumor samples in the CT images is significantly smaller than the number of background and kidney samples. with surrounding tissues and small tumor volumes, it’s still challenging to segment kidney and kidney tumor accurately. A proposal was submitted and accepted to hold this challenge in conjunction with MICCAI 2019 in Shenzhen China. 2.
