Is DeepStream suitable for face detection using MTCNN?

Hi @hotribao ,
Sorry for long delay!

I found topics below which can run mtcnn by TRT, seems they both do not mention image pyramid. Coul you share more details about image pyramid?

github.com/PKUZHOU/MTCNN_FaceDetection_TensorRT

src/mtcnn.cpp

master

#include "mtcnn.h"
//#define LOG
mtcnn::mtcnn(int row, int col){
    //set NMS thresholds
    nms_threshold[0] = 0.7;
    nms_threshold[1] = 0.7;
    nms_threshold[2] = 0.7;
    //set minimal face size (weidth in pixels)
    int minsize = 60;
    /*config  the pyramids */
    float minl = row<col?row:col;
    int MIN_DET_SIZE = 12;
    float m = (float)MIN_DET_SIZE/minsize;
    minl *= m;
    float factor = 0.709;
    int factor_count = 0;
    while(minl>MIN_DET_SIZE){
        if(factor_count>0)m = m*factor;
        scales_.push_back(m);
        minl *= factor;
