Abstract
An object count estimation apparatus () includes a first feature extraction network (), a first counting network (), a second feature extraction network (), and a second counting network (). The first feature extraction network () generates a first feature map () by performing convolution processing on a target image (). The first counting network () estimates the number of target objects having a size included in a first predetermined range by performing processing on the first feature map (). The second feature extraction network () generates a second feature map () by performing convolution processing on the first feature map (). The second existence estimation network () estimates the number of target objects having a size included in a second predetermined range by performing processing on the second feature map (). A size included in the first predetermined range is smaller than a size included in the second predetermined range.
