    • A region-of-interest (ROI) setting apparatus for respiration monitoring and a respiration monitoring system capable of setting an ROI in an automatic manner. Absolute values of subtractions between every successive two of a plurality of frame images photographed by a CCD camera 2 for a period of time equal to half a respiration period are calculated, then summed and stored. Based on the change information thus calculated and stored, the position and size of each changed region is calculated. Provisional regions are set from the changed regions successively from the greatest to the smallest one thereof. In each of these provisional regions, it is determined whether a gray level histogram indicative of distribution of the number of pixels for respective gray level values includes a twin peak characteristic having twin peaks each equal to or higher than a predetermined value, and whether the area of the corresponding changed region is equal to or greater than a predetermined value. One of the provisional regions that satisfies these conditions is set as an ROI.
    • 用于呼吸监测的感兴趣区域(ROI)设置装置和能够以自动方式设置ROI的呼吸监测系统。 计算由CCD照相机2拍摄的等于呼吸周期的一半的时间段的多个帧图像中的每个连续的两个之间的减法的绝对值,然后求和并存储。 基于这样计算和存储的变化信息,计算每个变化区域的位置和大小。 临时区域从连续变化的区域从最大到最小的一个设定。 在这些临时区域的每一个中,确定表示各个灰度值的像素数量分布的灰度级直方图是否包括具有等于或高于预定值的双峰值的双峰特性,以及区域 相对应的变化区域等于或大于预定值。 满足这些条件的临时区域之一被设定为ROI。
