Mean image for imagenet model (e.g., vgg16)

1

Are there any mean image file for the imagenet model such as vgg16?

From PyTorch ImageNet training script, you can find the mean value at here.

Thanks. But I think this is just the overall mean for normalization, but not the mean image? (3x256x256)

we dont have a full mean image (as it is not necessary to achieve convergence). We just compute one global mean value per image channel, instead of a mean image.
