Abstract:
1. A parameter setting method for setting parameters used in detecting an object from an image taken by a camera by processing the image based on the parameters, said parameter setting method comprising the steps of: when an object is detected, recording surveillance information including an image of the detected object and parameters used in the detection of the object; based on the recorded surveillance information, displaying on a display unit an image representing a result of the detection of the object and the parameters used in the detection of the object; correcting the parameters used in the detection of the object based on values input by an operator; performing again the detection of the object with respect to the image included in the recorded surveillance information based on the corrected parameters; displaying on the display unit a result of the detection of the object which was performed again, and the corrected parameters; wherein said parameters include at least one of: a reference image which is subtracted from the image taken by the camera to acquire a subtraction image, a threshold value for binarizing the subtraction image, a masking area where the binarized subtraction image is masked, and a range of object size which represents a size of a cluster of pixels within the binarized subtraction image to be detected.
