Recently in the group will explain the framework, in the feeling wild this small knowledge point, we began to produce ambiguity, today I will briefly explain this small knowledge point, but also to bring a beginner to the Receptive Field brand new understanding, if you have an in-depth understanding of just, you can just skip O(∩_∩)O~~!
Now to get down to business!!!
My understanding used to be that feeling wild, that's actually a visual perception area size. For a single layer network, a pixel point in the next layer whose perceptual field size is also the size of the convolutional layer filter is actually quite plainly understood when you think about it, but for multiple layers, that's a little (and just that little bit more complicated)!
In neural networks, the perceptual field is defined as
The size of the region mapped on the original image by the pixel points on the feature map (Feature ap) output from each layer of the convolutional neural network.
