Title: Raghav Khanna and Polarization-Based Stereo Imaging

Introduction

Raghav Khanna is an inventor based in Zurich, Switzerland. His listed patent work concerns using polarization data to improve the detection of corresponding pixels in stereo images. He is associated with Intrinsic Innovation LLC.

Latest Patents

Khanna is credited with 1 patent: “Polarized Semi-Global Matching.” The patent describes methods, systems, and computer programs for detecting pixel correspondences in stereo imaging using polarization data.

One method obtains images from two viewpoints in a stereo pair, along with angle-of-linear-polarization and degree-of-linear-polarization maps whose fields of view overlap the images. It uses those maps to compute a surface-normal map, then detects corresponding pixels by calculating a disparity map that minimizes an energy function. The function combines a pixel-matching cost with a polarized smoothness regularization term based on nearby pixels and the surface-normal map.

Career Highlights

The available information identifies Khanna’s work with Intrinsic Innovation LLC and highlights his contribution to polarization-informed stereo matching. The approach combines image correspondence analysis with surface-normal estimates derived from polarization measurements.
