Application of light field camera in diabetes intake management

Diabetes is a group of diseases in which the body has trouble regulating blood glucose. As concern for diabetes grows, the need for automated and accurate methods to monitor nutrient intake becomes essential for managing dietary. The challenging problem of the image-based dietary assessment is how to estimate food volume from a photograph taken with a camera. We present a design with aspherical surface of micro lens array approach for the novel digital imaging system using commercial optical software ZEMAX combined algorithm by using standard mathematical software MATLAB for the joint design process.
