Latest Patents

Hiroaki Nakai holds a patent for a region-of-interest (ROI) setting apparatus for respiration monitoring. This invention is designed to automatically set an ROI, which is crucial for effective respiration monitoring. The apparatus calculates absolute values of subtractions between successive frame images captured by a CCD camera over a time period equal to half a respiration cycle. These values are then summed and stored. Based on the calculated change information, the position and size of each altered region are determined. Provisional regions are established from the changed regions, starting from the largest to the smallest. The apparatus assesses whether the gray level histogram of each provisional region exhibits a twin peak characteristic and whether the area of the corresponding changed region meets a predetermined threshold. One of the provisional regions that fulfills these criteria is designated as the ROI.
