Talk Title: Chimera: NVIDIA's Mobile Computational Photography Architecture

Talk Abstract: Chimera, NVIDIA's computational photography architecture, was created to increase the flexibility of camera image processing pipelines and support new capture methods. This flexibility has become essential for the support of new sensors, including multi-camera and plenoptic methods, for many new bayer space algorithms, such as HDR and non-local means noise reduction, as well for post-demosaic algorithms such as image merging and local tone mapping. Chimera achieves this flexibility by creating a simplified framework to mix and match the ISP, the GPU and the CPU, allowing, for example, the GPU to be used in bayer space before the ISP for noise reduction, and the CPU after the ISP for scaling. In this talk we will discuss how the evolution of sensors and capture methods are shaping mobile imaging, and provide an overview of Chimera and the Always-on-HDR method.

Speaker's Biography: Ricardo Motta is a Distinguished Engineer at NVIDIA Corp, and the CTO responsible for imaging technology and roadmap for the Tegra mobile products. He is a graduate of the Imaging and Photographic Science program at RIT, where he developed the first colorimetric model for computer driven CRTs. He joined HP Labs in 1987 and was HP¹s first color imaging scientist, spearheading the development of HP¹s core color imaging products and technology, including the first color printers, copiers, cameras, and eventually the sRGB standard. From 1996 to 1999 he was a Chief Architect for HP's imaging business, then world¹s largest. In 1999 he left HP to start Pixim Inc, a pioneer in computational photography, where he was VP and CTO, leading the development of the first HDR video chipset. He is in the board of advisors of the Munsell Color Science Lab, and is a past vice president of IS&T.
