What is Tomnod?

Out in the real world, one of the best ways to find things or people that are lost, whether lost keys or lost kids, is to recruit help to find them. In a nutshell, that’s what Tomnod is. In fact, it has been called a “virtual search party”. Tomnod is a crowdsourcing application that lets …

Push and Pull

In the previous post, we’ve discussed the challenges of scaling object detection. We talked about how the traditional model of tiling images doesn’t quite fit because we need to be able to detect objects that span multiple tiles. In this post, we’ll examine the challenge of implementing a system that will do that efficiently. We …

Measuring Performance for Object Detectors – Part 2

This post is the second and final installment in my series about measuring the accuracy of models. In my last post, I talked about how to choose a method to score models. Now it’s time to use that method to score models against each other. Let’s start with a brief summary of the goal. We …

Frontness: Applications of Geospatial Object Detection

In my work on DeepCore, I have pleasure of being exposed to many of the applications that benefit from automated geospatial object detection. Machine learning is the key to unlocking data’s potential, and some of the applications are completely intractable without automated techniques. The DeepCore team has worked hard to develop software for these problems. …
