Abstract: What is disclosed is a system and method which reconstructs an N-pixel image of a scene such that Q pixel locations associated with identified regions of interest in a scene have a higher image quality when rendered relative to other pixels in the image. Acquisition and adaptive-quality compression are performed simultaneously by semi-synchronously or asynchronously temporally modulating an ordered set of sampling functions used to spatially modulate a pattern of light. The teachings hereof improve compression efficiency of a compressed sensing framework while improving encoding efficiency with respect to traditional compressed sensing techniques.

Abstract: What is disclosed is a system and method for representing a subject's state of mind given a plurality of physiological inputs. In one embodiment, a vector of physiological features is received. The vector of physiological features is provided to a psychophysiological model which comprises a plurality of models which fit the physiological features to psychological quantities, each representing a different state of mind. In a manner more fully disclosed herein, the psychological quantities are then aggregated to obtain an aggregate output that is representative of the subject's overall state of mind. Once the subject's state of mind has been represented, remedial action can then be taken.

Abstract: Systems and methods for assessing and managing stress of a user is provided. The system includes a wearable device that can be worn by the user; the wearable device include a sensing device for generating at least one time-series signal by continuous sensing of light intensity of light signals. The time-series signal includes at least one continuous photoplethysmographic (PPG) signal having an LF and an HF component. The system also includes a stress assessment device to determine a stress level of the agent based on a processing of the PPG signal. The stress assessment device further includes a feedback device configured by the processor to provide a feedback including at least one remedial message to the agent based on the determined stress level of the agent.
