Light Field LC-PolScope

Quantification of collagen organization in histopathology samples using liquid crystal based polarization microscopy.

A number of histopathology studies have utilized the label free microscopy method of Second Harmonic Generation (SHG) to investigate collagen organization in disease onset and progression. Here we explored an alternative label free imaging approach, LC-PolScope that is based on liquid crystal based polarized light imaging. We demonstrated that this more accessible technology has the ability to ...

Light Field Occlusion Removal

We present a novel method for detecting occlusions and in-painting unknown areas of a light field photograph, based on previous work in obstruction-free photography and light field completion. An initial guess at separating the occluder from the rest of the photograph is computed by aligning backgrounds of the images and using this information to generate an occlusion mask. The masked pixels ar...

The underwater light field

Light field moment imaging.

We introduce a novel imaging technique called light field moment imaging (LMI) that uses the continuity equation to extract the first angular moments of a light field. We use these moments to construct perspective views of a scene. Examples of LMI in photography and microscopy are presented.

Light Field Appearance Manifolds

Statistical shape and texture appearance models are powerful image representations, but previously had been restricted to 2D or 3D shapes with smooth surfaces and lambertian reflectance. In this paper we present a novel 3D appearance model using image-based rendering techniques, which can represent complex lighting conditions, structures, and surfaces. We construct a light field manifold captur...
