Abstract: Systems and methods for privacy-preserving optics are described. An embodiments includes a method of preserving-privacy on captured images while performing a computer vision task that includes generating an optimal set of parameters to parameterize an encoding optical element to produce optical distortions such that acquired images by the camera are distorted, where the optimal set of parameters is learned via end-to-end learning that jointly optimizes from a camera optics model to a computational process that performs a computer vision task on the distorted images acquired by the camera, where the distorted images visually obscure a privacy attribute of people to protect their privacy but still preserve features to perform the computer vision task, acquiring several distorted images, and performing a computer vision task directly on the distorted images where the distortions generated by the camera are optimal and allow obtaining high performance on the computer vision task.

An embodiment includes a system that includes an optical component and an image processing application configured to capture distorted video using the optical component, where the optical component includes a set of optimal camera lens parameters ?*o learned using machine learning, performing a machine vision task on the distorted video, where the machine vision task includes a set of optimal action recognition parameters ?*c learned using the machine learning, and generating a classification based on the machine vision task, where the machine learning is jointly trained to optimize the optical element and the machine vision task.

Abstract: Spectral imaging sensors and methods are disclosed. A spectral imaging sensor includes a color-coded array of apertures positioned to receive light from an object to be imaged. The array includes a first plurality of apertures configured to pass light in a first predetermined wavelength range and a second plurality of apertures configured to pass light in a second predetermined wavelength range different from the first predetermined wavelength range. The imaging sensor further includes one or more optical elements positioned to receive light passing through the color-coded array, and a photodetector positioned to receive light from the one of more optical elements. A spectral imaging method includes the steps of filtering light from an object to be imaged through a color-coded array of apertures, redirecting the filtered light with one or more optical elements, and receiving the redirected light with a photodetector.
