Image segmentation is the process of categorizing what is in a picture at a pixel level. For example, if you were given a picture with a person in it, separating the person from the image is known as segmentation and is done using pixel-level information.
We will be using the COCO dataset for image segmentation.
Following is what you should do before executing any of the SegNet scripts:
cd SegNet
wget http://images.cocodataset.org/zips/train2014.zip
mkdir images
unzip train2014.zip -d images
When executing SegNet scripts, make sure that your present working directory is SegNet.
