Computer Vision News - July 2016

Every month, Computer Vision News shows you a nice trick that will make your work easier… This time, our engineers have decided to tell you how to visualize a 3D kidney segmentation using simple Matlab script… Image segmentation is the process of partitioning a digital image into various regions of interest. In the medical domain, image segmentation is mainly the boundaries of organs in X-ray, CT or MRI scans . With the trick of this month we will demonstrate how to visualize a 3D kidney segmentation using simple Matlab script. Our input to this process is kidney segmentation from a CT scan (kidneyImage): which is a 3D matrix with the Hounsfield Unit (HU) values inside the kidney and zero elsewhere. We will demonstrate two visualizations of this segmented kidney. In the first one, we will generate a three-dimensional view of the kidney surface. In the second one, we will add the kidney interior layer for observing the content of the kidney. 1. A three-dimensional view of the kidney surface: Here is the Matlab code snippet for this visualization: 24 Computer Vision News Trick Visualization of 3D medical image segmentation Trick
