Our ODSC talks in video

As we previously announced, the last couple of weeks we’ve been launching Luminoth, our brand new open source toolkit for Computer Vision. As part of this launch, we gave talks in the Open Data Science Conference (ODSC), both at the London and San Francisco editions.

The events were a great success, as in 5 days they accumulated around 5000 data scientists, while hosting more than 200 talks from renowned people in the academia and industry. There was a great atmosphere to meet people interested and working in the field. Our congratulations to the organizers, it was a very neat experience!

With regards to our presentations, there were two talks hosted by Alan Descoins (Tryolabs CTO) and Javier Rey (Tryolabs Lead Research Engineer) titled “Building an Object Detection toolkit with TensorFlow: From academic papers to open source implementation”.

The talks got pretty good reception from the audience (here you can find a review of the SF event that has some good words for our talk!), generated interesting discussions with some of the +400 attendees, and also paved the way for actual interest in Luminoth, which keeps steadily growing its popularity in Github.

If you’re not yet convinced about watching our talk, find below the abstract and the slides; hopefully it gets you interested in how Deep Learning for object detection works ;)

In recent years, models based on Convolutional Neural Networks (CNNs) have revolutionized the entire field of computer vision. Problems like image classification can now be considered solved, and it is easy to construct implementations with any modern Deep Learning framework using fine tuning with pre-trained weights on datasets such as ImageNet. However, the harder problems of object detection and segmentation require much more complex methods to solve. Object detection consists of picking up the objects and drawing a rectangular bounding box, while segmentation aims to identify the exact pixels that belong to each object. One of the main differences with image classification is that the same image may contain several objects and those could be in very different proportions, sizes, lighting and partially occluded. In this talk, we will discuss how state of the art object detection techniques work. In particular, we will take a look at Region Proposal Networks (RPNs), which propose candidate object locations (“proposals”) which are later refined to achieve precise localization. We will then look at the architecture of an object detection system, and the performance considerations of different algorithms. Moreover, we will explore an implementation of an open source Python object detection toolkit based on TensorFlow, going through the details and tricks of the trade when using such ecosystem on production ready applications.
