If you look at the 'pictures' inside a CNN layer, and some parts are very bright, what does that tell you about what the network found in the image?

The 'pictures' inside a CNN layer are technically called feature maps, also known as activation maps. Each feature map is the output produced by a specific convolutional filter, or kernel, after it has processed the input image or a feature map from a preceding layer. A very bright part within one of these feature maps indicates a high activation value at that specific location. This high activat....
