Property Documentation

  - 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
