Moving object detection apparatus, control method for moving object detection apparatus, and non-transitory computer-readable storage medium

A control method for a moving object detection apparatus, comprising:

• inputting an image captured by a capturing unit and setting an image capturing parameter;
• generating a background model based on a feature of a background region of the image that is input by the inputting;
• saving, in a memory, a background model in association with the image capturing parameter;
• detecting a moving object region from an image input by the inputting based on the background model;
• and
• determining, in a case where the image capturing parameter set in the setting is changed, whether to use a background model saved in the memory for detecting the moving object region, based on an amount of change in the moving object region detected for a first image which is captured before the image capturing parameter is changed and a second image which is captured after the image capturing parameter is changed,
• wherein in a case where the image capturing parameter set by the setting is changed, a background model corresponding to the changed image capturing parameter is acquired from the memory, and a moving object region is detected from the second image using the acquired background model.

A non-transitory computer-readable storage medium storing a program for causing a computer to execute a control method for a moving object detection apparatus, the method comprising:

• inputting an image captured by a capturing unit and setting an image capturing parameter;
• generating a background model based on a feature of a background region of the image that is input by the inputting;
• saving, in a memory, a background model in association with the image capturing parameter;
• detecting a moving object region from an image input by the inputting based on the background model;
• and
• determining, in a case where the image capturing parameter set in the setting is changed, whether to use a background model saved in the memory for detecting the moving object region in the detecting, based on an amount of change in the moving object region detected for a first image which is captured before the image capturing parameter is changed and a second image which is captured after the image capturing parameter is changed,
• wherein in a case where the image capturing parameter set by the setting is changed, a background model corresponding to the changed image capturing parameter is acquired from the memory, and a moving object region is detected from the second image using the acquired background model.
