Function Usage

Obtains the AIPP (static or dynamic) configuration of a model. To obtain the dynamic AIPP configuration, this API call returns the values of only the following parameters in the aclAippInfo struct: srcFormat, srcDatatype, srcDimNum, shapeCount, and outDims.

Dynamic AIPP provides the following functions and they are executed in the exact sequence: Cropping -> CSC -> Mean subtraction/normalization -> Padding.
