Moving object detection apparatus

A method for monitoring a moving object, comprising the steps of:

• setting a window area of interest for an inputted time-varying image;
• calculating a correlation between a reference data of the window area in a reference frame and a current data of the window area in a current frame;
• deciding whether images of the window area of the current frame includes an image of a moving object correlation value over a predetermined time period;
• and
• updating the reference data as the current data when the image of the window area of the current frame does not include the image of the moving object.

A method for monitoring a moving object, comprising the steps of:

• setting a window area of interest for an inputted time-varying image;
• calculating a correlation between a reference data of the window area in a reference frame and a current data of the window area in a current frame;
• deciding whether images of the window area in the current frame is a background image which is a reference image for detecting a moving object, based on a plurality of calculated correlation values;
• and
• updating the reference data as the current data when the image of the window area in the current frame is a background image.

A method for monitoring a moving object, comprising the steps of:

• setting a window area of interest for an inputted time-varying image;
• calculating a correlation between a first data of the window area in a frame (A) and a second data of the window area in a frame (B);
• and
• deciding an interval in which an image of the window area changes temporarily, based on a plurality of calculated correlation values.

A monitoring system, comprising:

• a TV camera for taking in time-varying images;
• a computer for monitoring the time-varying images;
• and
• a display for displaying the result of the monitoring;
• wherein said computer calculates a correlation between a first data of a window area in a frame (A) and a second data of the window area in a frame (B) and decides a interval in which a moving object is present in the window area based on a pattern of a calculated correlation value over a predetermined time period;
• and
• wherein said display displays a representative screen of the time-varying images in the first interval.

A monitoring system, comprising:

• a TV camera for taking in time-varying images;
• a computer for monitoring the time-varying images;
• and
• a display for displaying the result of monitoring;
• wherein said computer calculates a correlation between a reference data and a current data of the window area in a current frame and decides whether an image of the window area of the current frame includes an image of a moving object or not based on a pattern of a calculated correlation value over a predetermined time period.
