*@brief Performs AI pre-processing (AIPP) on images including color space conversion (CSC),

*@li images: An NCHW or NHWC tensor of type uint8, specifying the input to the data layer.
*@li params: Dynamic AIPP configuration parameters of type uint8. \n

*@par Attributes:
*aipp_config_path: A required string, specifying the path of the AIPP configuration file. \n

*@par Outputs:
*features: The AIPP-processed output tensor of type float16 or uint8.
*@par Third-party framework compatibility
* It is a custom operator. It has no corresponding operator in Caffe.
*@par Restrictions:
*Warning: This operator can be integrated only by configuring INSERT_OP_FILE of aclgrphBuildModel. Please do not use it directly.
