Claim 17:
18. A system comprising a processor and a memory storing a program when executed by the processor to perform a method comprising receiving by a learned model that is learned to output, as a prediction result, one or more element points which constitute a linear structure from an input image, the model comprising, wherein the learned model comprises: a first processing module that receives the image and generates a feature map representing a feature amount of the image by convolution processing; and a second processing module that calculates a shift amount from a unit center point to the element point of the linear structure closest to the unit center point, for each unit obtained by dividing the feature map into a plurality of the units including regions having a predetermined size in a grid pattern, wherein the second processing module disposes anchors, which are one or more reference shape regions having predetermined shape and size, in each of the units, and performs, for each unit, the convolution processing by using the feature amount at a position of the unit to calculate the shift amount for moving an anchor center point of the anchor to a closest point, which is the element point of the linear structure closest to the anchor center point, and a score for determining whether or not the linear structure is present in the anchors.
