1. An image foreground detection apparatus, comprising:

  • a first detector configured to perform foreground detection on each pixel of an input image, the first detector comprising;

    a first calculator configured to calculate a first difference between a pixel value of the pixel and sample values in a background model corresponding to a position where the pixel is located;

    a first updating unit configured to, when the number of sample values in the background model of the first difference less than or equal to a first threshold is greater than or equal to a second threshold, replace a pixel value of a sample value in the background model of which the first difference is maximum with the pixel value of the pixel by a predetermined probability, to update the background model of the position where the pixel is located; and

    a first determining unit configured to, when the number of sample values in the background model of the first difference less than or equal to the first threshold is less than the second threshold, determine the pixel as a foreground pixel.
