Compact Rotation Invariant Image Descriptors By Spectral Trimming

Abstract: Image descriptors are widely used in applications such as object recognition, pattern classification and image registration. The descriptors encode the local visual content of the image to provide a compact, robust and distinctive representation of objects.

A (256*256) pixel 76.7mW CMOS imager/ compressor based on real-time in-pixel compressive sensing:

Abstract: A CMOS imager is presented which has the ability to perform localized compressive sensing on-chip. In-pixel convolutions of the sensed image with measurement matrices are computed in real time, and a proposed programmable two-dimensional scrambling technique guarantees the randomness of the coefficients used in successive observation.

Optical tomography based on phase-shifting schlieren deflectometry

Abstract: We present a new optical tomography technique based on phase-shifting schlieren deflectometry. The principle is that of computerized tomography. The three-dimensional profile is reconstructed from the deflection angles of rays passing through the tested object.
