StackGAN has got nearly 200 citations since first appeared on arXiv on December 10, 2016. The StackGAN is the first to generate 256*256 image with photo-realistic details from text description. Generative Adversarial Network (GAN), originally proposed by Ian. It takes advantage of a generator network and a discriminator. The generator is trained to fool…
[Summary] Omnipresence 3D for Multiview Mixed Reality
Christian Laforte leads the development of Fortem’s Omnipresence 3D software. It helps organizations prevent costly mistakes and respond to incidents in record time — protecting our communities against increasingly complex security threats. This is definitely a great leap of my prior work, VideoFields. At the time, I was offered only three surveillance video cameras and would…
[Summary] PointNet, PointNet++, and PU-Net
Shuo Li presented a talk at GVIL weekly seminar: PointNet, PointNet++, and PU-Net PointNet Instead of 3D convolution, PointNet directly consumes point clouds, which well respects the permutation invariance of points in the input. A point cloud is an unordered set of vectors. Each point Pi is a vector of its (x, y, z) coordinate plus extra…
Gradient, Circulation, Laplacian, Divergence, Jacobian, Hessian, and Trace
Here is a summary of all these concepts. Most the concepts are from Wikipedia. A larger figure is shown below: In mathematics, the gradient is a multi-variable generalization of the derivative. While a derivative can be defined on functions of a single variable, for functions of several variables, the gradient takes its place. The gradient…
[Summary] Talk by Dr. Chakareski: Networked Virtual and Augmented Reality: The New Frontier
Jacob Chakareski is an Assistant Professor of Electrical and Computer Engineering at The University of Alabama, where he leads the Laboratory for VR/AR Immersive Communication (LION). His interests span networked virtual and augmented reality systems, UAV-IoT sensing and communication, and rigorous machine learning for stochastic control. Dr. Chakareski received the Adobe Digital Experience Faculty Research…
