Generalized Scene Reconstruction (GSR)

Generalized Scene Reconstruction (GSR) is the process of creating photorealistic 5D models of generalized scenes from digital images. Quidient proclaims GSR to be the Final Frontier of Photography because the world is represented the same way that humans perceive it (in 5D). By the way, you know “crime scene reconstruction” from TV series like “CSI.” Generalized Scene Reconstruction just generalizes the concept to any scene on Earth. GSR in ubiquitous devices like smartphones and AR glasses is called Ubiquitous GSR (uGSR).

Generalized Scene. A region in space that contains virtually any type of light or material that people encounter in the course of their daily lives. Generalized scenes include objects that are shiny, partially transmissive, featureless, and finely structured. Modern kitchens, contemporary offices, and flower gardens are examples of generalized scenes.

Light Field Physics

Light transport theory describes how a given material emits, absorbs, reflects, scatters or transmits various frequencies of light. Quidient decouples the light field from the matter field by using transport theory to represent materials such as metal, wood, glass, and even fog. This decoupling leads to significant advantages in machine learning / AI as well as scene compression and processing speeds.

Spatial (5D) Database

Quidient’s Plenoptic (5D) Database technology represents a major shift in underlying architecture.  It provides a novel means for separately encoding a matter field (as 3D Voxels, shown in turquoise) coincident with any light field (as 2D solid-angle elements, Saels, shown in yellow). This spatially sorted, hierarchical approach leads to randomly accessible and searchable scenes with exceptionally fast subscene insertion and extraction. This is a critical requirement for representing scenes with virtually unlimited levels of detail such as an interactive city map.

Conventional & Polarimetric Imaging

Quidient’s engines are enabled to work with both conventional and polarimetric cameras. Traditional monochrome and color sensors capture the visible color and brightness of a light wave interacting with a material. Polarimetric sensors capture additional information, the light wave’s non-visible “rotational orientation.” When available, this additionally captured information provides important advantages in GSR, especially when dealing with featureless surfaces and low lighting conditions. Quidient’s solution is highly configurable and enabled to use a broad range of individual and/or combination of sensors including today’s newest polarimetric cameras to optimize the scene reconstruction process.

Let’s Change the World Together

The notion of “Changing the World” is not a cliché for us. Generalized Scene Reconstruction is a pioneering approach to 3D imaging. All of us on Quidient’s team are optimistic that thousands of GSR-enabled applications will soon transform the way people live and work. We have key positions open for brilliant scientists, digital developers and entrepreneurs.
