# Applying filters learned from convolutional neural networks

I have a neural network that I trained on 32 * 32 px size images. Can I use these filters learned from the network on larger images not used in training the network such as a 600 * 800 px image? Or does it not make any sense to apply filters that were learned on smaller images on larger images and vice versa?

Here is an example of some images: An image from training set

Here is a random image that I got online to test

Here is when I applied the filter(s)

• If you give me sample images, both the 32x32 and the 600x800 then I might be able to give R-code in my answer. I'm assuming they are grayscale. – EngrStudent Apr 30 '16 at 23:25

Can I use convolutional filters used on 32x32 px size images upon 600x800px images?
