The present invention provides a technique suitable for the detection of small objects such as white canes.
In order to solve this problem, one representative example of this image processing system comprises a video acquisition unit configured to input an input image acquired as a video, an estimation unit including a Fully Convolutional Network (FCN) learning model trained with respect to a region of a predetermined detection target, and configured to generate a region estimation image for the detection target by processing the input image with the learning model, and an image processing unit configured to detect the region of the detection target based on the region estimation image.
