Hi, I'm Siddhant! I'm pursuing a Ph.D. under the supervision of Dr. George Drettakis with the GraphDeco group at INRIA Sophia Antipolis-Méditerranée. In my research I study photorealistic rendering of real environments using captured media such as digital images and videos. My Ph.D. is supported by the ERC Advanced Grant FUNGRAPH.

I graduated with a Master’s degree in Computer Science from Arizona State University, co-advised by Prof. Robert LiKamWa and Prof. Yezhou Yang. During my masters, I looked into problems at the intersection of visual computing and mobile systems, designing novel system and algorithms to improve mobile mixed-reality experiences. Previously, I obtained a B.Tech (Hons.) in Computer Science and Engineering from IIIT Hyderabad, where I was advised by Prof. P J Narayanan as an honors student. In my honors project, I explored the area of computational photography and digital image representation.

My interest in visual computing stems from my fascination with photography. I love capturing candid moments and particularly enjoy travel and concert photography. Checkout few of my captures on my PhotoBlog and follow me on Instagram to see the world as I see it!

Software

System for Image-Based Rendering (SIBR)

Sebastien Bonopera, Peter Hedman, Jerome Esnault, Siddhant Prakash , Simon Rodriguez, Theo Thonat, Mehdi Benadel, Gaurav Chaurasia, Julien Philip, and George Drettakis

The System for Image-Based Rendering or SIBR, is a specialized collection of libraries and toolkits for quickly implementing Image-Based Rendering (IBR) algorithms, and includes implementations of several published IBR papers, mainly from Inria and UCL, but also (re-implementations) of projects from other research groups. My contributions include designing the current core/projects structure in addition to clean-up towards code release.

Torch to Caffe2 Model Converter

Siddhant Prakash, Anurag Ranjan, and Raffi Enficiaud

Step-by-Step instructions to convert a Torch model to Caffe2 model. The software takes a pre-trained Torch model and its network parameters as input and creates its copy to run with a Caffe2 network.

Arachnophobia

Siddhant Prakash

Arachnophobia is a 2D game using OpenGL. It is one of the first graphics code I wrote for my introductory computer graphics course assignment. You can shoot spiders, or catch them in buckets to save your base! The code gives an overview of all basic OpenGL calls required to create a scene and render it from scratch using primitive geometry.
