1. A system comprising: one or more processors; and a memory comprising instructions stored thereon that, responsive to execution by the one or more processors implement an image classification network, the image classification network comprising: an image separator configured to separate an image into a grayscale channel of the image and a color channel of the image, the image comprising a color image; a first column of grayscale filters configured to receive the grayscale channel of the image and extract grayscale features from the grayscale channel of the image; a second column of color filters configured to receive the color channel of the image and extract color features from the color channel of the image, wherein the image classification network has a greater number of grayscale filters than color filters; an image classifier configured to identify an object in the image based on the extracted grayscale features and the extracted color features, and classify the image based on the identified object.
