Image recognition method, image recognition device, and recording medium

An image recognition device comprising:

• an image input unit that receives an image;
• a convolution processor that acquires processing result information including values of processing results of convolution processing at positions of a plurality of pixels that constitute the image by performing the convolution processing on the image by using different convolution filters, determines 1 feature for each of the positions of the plurality of pixels on the basis of the values of the processing results of the convolution processing at the positions of the plurality of pixels included in the processing result information, outputs the determined feature for each of the positions of the plurality of pixels;
• a recognition processor that performs recognition processing on the basis of the determined feature for each of the positions of the plurality of pixels that is output by the convolution processor;
• and
• a recognition result output unit that outputs recognition processing result information obtained by performing the recognition processing in the recognition processor.

A non-transitory computer-readable recording medium storing a program for causing a computer of an image recognition device to:

• receive an image;
• acquire processing result information including values of processing results of convolution processing at positions of a plurality of pixels that constitute the image by performing the convolution processing on the image by using different convolution filters;
• determine 1 feature for each of the positions of the plurality of pixels on the basis of the values of the processing results of the convolution processing at the positions of the plurality of pixels included in the processing result information and output the determined feature for each of the positions of the plurality of pixels;
• perform recognition processing on the basis of the determined feature for each of the positions of the plurality of pixels;
• and
• output recognition processing result information obtained by performing the recognition processing.
