1. An image recognition method performed by a computer of an image recognition device, comprising: receiving an image; acquiring first processing result information including values of a first processing result of first convolution processing at positions of a plurality of pixels that constitute the image by performing the first convolution processing on the image by using a first convolution filter; acquiring second processing result information including values of a second processing result of second convolution processing at positions of a plurality of pixels that constitute the image by performing the second convolution processing on the image by using a second convolution filter that is different from the first convolution filter in resolution, scale parameter or color to be processed; determining one feature for each of the positions of the plurality of pixels on the basis of the values of the first processing result and the second processing result at the positions of the plurality of pixels included in the first processing result information and the second processing result information and outputting the determined feature for each of the positions of the plurality of pixels; performing recognition processing on the basis of the determined feature for each of the positions of the plurality of pixels; and outputting recognition processing result information obtained by performing the recognition processing.
