Summary Adaptive methods influenced by control theory and information theory can dramatically improve and enlarge today’s imaging and display platforms, enabling capabilities …
StreetScore is an algorithm that assigns a score to a street view based on how safe it looks to a human — but using a computer. The StreetScore algorithm was created by Nikhil Naik as part of a collaboration between …
Low-cost cell-phone attachments that measure the eye-glass prescription and cataract information from the eye.
With simplified optics and clever illumination, we visualize images of the retina in a standalone device easily operated by the end user, enabling disease diagnosis.
A frugal camera design exploiting the fundamental dictionary of light fields for single-shot capture of light fields at full sensor resolution.
Using short laser pulses and a fast detector, we built a device that can look around corners with no imaging device in the line of sight using scattered light and time resolved imaging.
We repurpose a time-of-flight camera using coded illumination to recover time profiles of large-scale scenes and to acquire multiple depths per pixel.
A camera fast enough to capture light pulses moving through objects. We use ‘light in motion’ to understand reflectance, absorption and scattering properties of materials.
Compressive light field displays employing a stack of time-multiplexed, light-attenuating layers with uniform or directional backlighting. They exhibit increased brightness and refresh rate.
A new camera that allows single-capture full-resolution non-planar focal surfaces imaging, post-capture refocusing, and 3D imaging.
A new camera design with switchable color filter arrays for optimal color fidelity and picture quality on scene geometry, color, and illumination.
A camera that codes exposure time with a binary pseudo-sequence to deconvolve and remove motion blur in textured backgrounds and partial occluders.
We analyze sampling strategies for reconstructing visual signals from a limited number of non-adaptive linear projections.
3D reconstruction of objects from a single shot photo using spacial heterodyning.
Tomographic techniques for image synthesis on displays composed of compact volumes of light-attenuating material. They can recreate 4D light field or high-contrast 2D image.
A thin, depth-sensing LCD for 3D interaction using light fields which supports both 2D multi-touch and unencumbered 3D gestures.
By capturing and displaying a 4D light field, it can create arbitrary patterns directional illumination patterns and record their interaction with physical objects.
Combining sampling, rendering, and display-specific optimization into a single framework, the algorithm facilitates light field synthesis with reduced computational resources.
A compact, fast CAT scan machine using no mechanical moving parts or synchronization.
We utilize high spatio-frequency patterns with state of the art dictionary learning algorithms to enhance vein structures under the skin.
