Abstract: The present invention provides a method comprising the steps of: generating a second anchor on the second convolutional feature map by scaling and shifting a first anchor in the ground-truth box; generating a third convolutional feature map by convolving the second convolutional feature map by means of a second convolution; determining whether the overlap ratio between the ground-truth box and a second single anchor is greater than or equal to a reference value; generating a third anchor by scaling and shifting the second anchor having an overlap ratio that is greater than or equal to the reference value; assigning an objectivity score to the third anchor; and presenting the third anchor, which has an objectivity score that is equal to or greater than a reference value, as a proposal on the third convolutional feature map.
