"What from Where. In 3D! Learning Semantic Segmentation from 3D Models"

Abstract:

We address the challenge of classifying pixels in aerial images of urban areas which can provide crucial data for various applications such as mapping, 3D modeling and navigation. Fully Convolutional Networks are very well suited to handle image segmentation; however generating enough annotated data is very costly.

We present a semi-supervised system to annotate an entire urban 3D model generated from Multi-View Stereo. The annotated model is then back projected onto thousands of images that are then used to train the network. The exact world location of every pixel, provided by the model, enables a variety of geometric features, simplifying the semantic annotation. We introduce a novel loss function to optimize the F1 score calculated over the entire batch. We present results on multiple data-sets and compare results with and without depth information.

Piecewise Planar and Non-Planar Segmentation of Large Complex 3D Urban Models

Our paper published in 3DV is now online. I will also be giving a talk in the Israeli Machine Vision Conference next month (in case you missed me in Tokyo)

Darpa challenge to maneuver and navigate at high speed though unfamiliar clutter. I don't know of any systems that dexterous, that small, with that kind of awareness of the surroundings. This is indeed an ambitious goal.

Did you know more Americans die by suicide than in car accidents?
Cancer is on the rise because of aging population (I'm sure the jury is still out on that one)?
A very cool illustration of mortality trends over the years.

That's awesome.
Have you seen the Action Movie Kid?

His dad uses (really good) special effects to bring his son's fantasy world to life. Incredible.

Enjoy y'all
To celebrate World Book Day, my tale of love, loss, rock stars, drama and orange utans - Backpackers- will be free on e book until Sunday. Please feel free to share. Thanks x

I know the last few days are like a stress test in Jerusalem, but the App is doing a horrible job. I sat at the station for 40 minutes with a notice that the bus ("real time report") is 19 minutes away. The bus kept vanishing and reappearing a few stops back.

Playing with my android/Lego/arduino project. going to add vision now. However the time between sessions is so long I have to update, remember where I installed opencv4android, how the native connects to the android java...
The work to catchup ratio is horrible
