The idea behind the Batch Normalization is very simple: given tensor with L feature maps it performs a standard normalization for each of its channels. This is, for every feature map l ∈ L, subtract its mean and divide by its standard deviation (square root of variance): ( l- μ) / σ. Visually it can be depicted as shown below. my people works
