Information processing apparatus, control method, and program

A control method which is executed by a computer, the method comprising:

• determining whether or not a first foreground area represents a moving object, the first foreground area being extracted from a first captured image generated by a camera;
• and
• outputting warning when it is determined that the first foreground area does not represent a moving object,
• wherein the determination includes:
• performing first determination of determining whether or not an object represented by the first foreground area is moving by comparing the first foreground area with a second foreground area, the second foreground area being a foreground area extracted from a second captured image that is generated by the camera before the first captured image, the second foreground area representing a same object as the first foreground image;
• acquiring history information which represents information regarding the object represented by the first foreground area at time before the first captured image is generated;
• performing second determination of determining whether or not the object represented by the first foreground area is moving at the time before the first captured image is generated based on the acquired history information;
• and
• determining that the first foreground area does not represent the moving object when the object represented by the first foreground area is determined to be not moving by both of the first determination and the second determination.

A non-transitory computer-readable storage medium storing a program causing a computer to execute:

• determining whether or not a first foreground area represents a moving object, the first foreground area being extracted from a first captured image generated by a camera;
• and
• outputting warning when it is determined that the first foreground area does not represent a moving object,
• wherein the determination includes:
• performing first determination of determining whether or not an object represented by the first foreground area is moving by comparing the first foreground area with a second foreground area, the second foreground area being a foreground area extracted from a second captured image that is generated by the camera before the first captured image, the second foreground area representing a same object as the first foreground image;
• acquiring history information which represents information regarding the object represented by the first foreground area at time before the first captured image is generated
• performing second determination of determining whether or not the object represented by the first foreground area is moving at the time before the first captured image is generated based on the acquired history information;
• and
• determining that the first foreground area does not represent the moving object when the object represented by the first foreground area is determined to be not moving by both of the first determination and the second determination.
