- alpha [read], [write], [nonatomic], [assign]

The value of alpha. Default is 0.0 The default value 0.0 is not recommended and is preserved for backwards compatibility. With alpha 0, it performs a local mean subtraction. The MPSCNNLocalContrastNormalizationNode used with the MPSNNGraph uses 1.0 as a default.

- beta [read], [write], [nonatomic], [assign]

The value of beta. Default is 0.5

- delta [read], [write], [nonatomic], [assign]

The value of delta. Default is 1/1024

- (NSUInteger) kernelHeight [read], [nonatomic], [assign]

- (NSUInteger) kernelWidth [read], [nonatomic], [assign]

- p0 [read], [write], [nonatomic], [assign]

The value of p0. Default is 1.0

- pm [read], [write], [nonatomic], [assign]

The value of pm. Default is 0.0

- ps [read], [write], [nonatomic], [assign]

The value of ps. Default is 1.0
