At Athelas, we use Convolutional Neural Networks(CNNs) for a lot more than just classification! In this post, we’ll see how CNNs can be used, with great results, in image instance segmentation.

Ever since Alex Krizhevsky, Geoff Hinton, and Ilya Sutskever won ImageNet in 2012, Convolutional Neural Networks(CNNs) have become the gold standard for image classification. In fact, since then, CNNs have improved to the point where they now outperform humans on the ImageNet challenge!

CNNs now outperform humans on the ImageNet challenge. The y-axis in the above graph is the error rate on ImageNet.

While these results are impressive, image classification is far simpler than the complexity and diversity of true human visual understanding.

In classification, there’s generally an image with a single object as the focus and the task is to say what that image is (see above). But when we look at the world around us, we carry out far more complex tasks.
