Abstract
A method for rapidly calculating intersection over union (IOU) between a target region and a designated region in an image is used in an electronic device. The electronic device detects a target object from an image received from a monitored location, and determines a designated region, a target region, and a combined region from the image, the target region including the target object. The electronic device calculates a first area of the designated region, a second area of the target region, and a third area of the combined region, and calculates a value of IOU according to formula of SIOU=(S1+S2−S3)/S2. S1 represents the first area, S2 represents the second area, and S3 represents the third area. The electronic device issues an intrusion warning in or concerning a monitored region according to a comparison result between the value of IOU and a preset threshold.
