[0200] Figure 11 is a block diagram showing an image processing apparatus according to a second embodiment of the present invention. The image processing apparatus according to the second embodiment uses Figure 1B The configuration shown in is the basis. It should be noted that, in order to avoid duplication of description, in the following description no longer figure 2 Parts common to the first embodiment described.

[0201] The second embodiment differs from the first embodiment in that, in the case of the second embodiment, the background feature amount holding section 202 employed in the first embodiment is replaced by an average value holding section 1102 . The average value holding section 1102 is a unit for calculating the average value of the feature quantities calculated for the image portion by the feature quantity calculation section 114 and storing the calculated average value.

[0202] The difference calculation section 116 calculates the difference betwee...

Abstract

Disclosed herein is an image-processing apparatus which may include an image holding section configured to store an input image; an image division section configured to divide the input image stored in the image holding section into a plurality of image portions having the same size and the same shape; a characteristic-quantity computation section configured to compute a characteristic quantity of each of the image portions generated by the image division section; and a difference computation section configured to carry out a difference computation process of computing a difference between the characteristic quantity computed by the characteristic-quantity computation section as the characteristic quantity of each individual one of the image portions generated by the image division section and a value determined in advance as well as a determination process of producing a result of determination as to whether or not the individual image portion is a portion of a background of the input image on the basis of the difference.

Description

technical field [0001] The present invention relates to an image processing device, an image processing method, and an image processing program. More specifically, the present invention relates to a technology suitable for detecting unknown objects and / or suspicious individuals from images obtained by using a surveillance camera to photograph a predetermined monitored place. Background technique [0002] In the related art, there is a monitoring system for monitoring a predetermined object by using a monitoring camera. In this monitoring system, a monitored object is monitored by visually recognizing an image obtained from a photographing operation with a monitoring camera as an image of the monitored object. [0003] However, as the number of places to be monitored increases, it is difficult for surveillance personnel to continuously perform surveillance operations for 24 hours using such surveillance cameras. In addition, in order to shorten operation time, the surveilla...
