yolov3 tiny c代码

以下是使用Darknet框架实现的YOLOv3 Tiny的C代码示例：

#include <stdio.h>
#include <stdlib.h>
#include <string.h>

#include "darknet.h"

#define MAX_DETECTIONS 100

int main(int argc, char **argv)
{
    char *cfg_file = "cfg/yolov3-tiny.cfg";
    char *weights_file = "yolov3-tiny.weights";
    char *image_file = "data/dog.jpg";

    if (argc > 1) {
        image_file = argv[1];
    }

    // Load network
    network *net = load_network(cfg_file, weights_file, 0);
    set_batch_network(net, 1);

    // Load image
    image im = load_image_color(image_file, 0, 0);

    // Run detection
    float thresh = 0.5, hier_thresh = 0.5;
    int nms = 0;
    detection *dets = calloc(MAX_DETECTIONS, sizeof(detection));
    int num_detections = 0;
    detect_image(net, im, thresh, hier_thresh, nms, dets, &num_detections);

    // Print detections
    int i;
    for (i = 0; i < num_detections; ++i) {
        printf("%s: %.0f%%\n", net->names[dets[i].class], dets[i].prob * 100);
    }

    // Free memory
    free_detections(dets, num_detections);
    free_image(im);
    free_network(net);

    return 0;
}
