Summary of the Inventive Concept

A system and method for camera-based stress determination, providing more accurate and efficient stress level analysis through multi-spectral imaging, advanced processing, and personalized feedback.

Background and Problem Solved

The original patent's camera-based stress determination system had limitations in terms of accuracy and efficiency. The new inventive concept addresses these limitations by introducing a multi-spectral camera, advanced processing unit, and personalized feedback module, enabling more accurate stress level analysis and effective stress reduction.

Detailed Description of the Inventive Concept

The enhanced system comprises a multi-spectral camera for capturing image sequences in multiple spectral bands, a processing unit trained to determine a set of bitplanes from the captured image sequences, and a stress level analyzer for determining a stress level of a human individual based on the determined set of bitplanes. The processing unit is trained using an HC changes training set and a stress level training set, enabling accurate analysis of bitplanes in each spectral band. The system also includes a feedback module for providing personalized stress-reduction recommendations based on the determined stress level.

Novelty and Inventive Step

The new claims introduce the use of multi-spectral imaging, advanced processing, and personalized feedback, which are not present in the original patent. The inventive step lies in the combination of these features to provide a more accurate and efficient stress determination system.
