Function Usage

Obtains the number of Region Proposals in the queue processed by MrgSort and stores the number in the four output parameters in sequence.

This API works with MrgSort as follows:

It is used together with MrgSort4 to obtain the number of Region Proposals in the queue processed by MrgSort4. To use this API, you need to set the MrgSort4Info.ifExhaustedSuspension parameter in MrgSort4 to true. In this configuration mode, after a queue is exhausted, the MrgSort4 instruction stops.
The preceding description applies to the following models:
