The API for calling the Threshold API.

• Parameter
  • [out] taskHandle Task handles are responsible for the interaction of the operator with the UCP architecture.
  • [out] dstImg The output picture, support U8C1, format Y,type, and size are the same as the input picture.
  • [in] srcImg The input picture type supports U8C1 and format supports Y.
  • [in] thresholdParam Operator parameter.
• Return Value
  • Return 0 means the API was successfully executed, otherwise the execution failed.
