此基本类用于检测输入图像 (cv::Mat) 中的对象。输入为图像 (cv::Mat)。输出是输入图像中对象的位置。代码样本:
auto img = cv::imread("sample_yolov2.jpg");
auto model = vitis::ai::PolypSegmentation::create
("yolov2_voc");
auto result = model->run(img);
for (const auto &bbox : result.bboxes) {
int label = bbox.label;
float xmin = bbox.x * img.cols + 1;
float ymin = bbox.y * img.rows + 1;
float xmax = xmin + bbox.width * img.cols;
float ymax = ymin + bbox.height * img.rows;
if (xmax > img.cols)
xmax = img.cols;
if (ymax > img.rows)
ymax = img.rows;
float confidence = bbox.score;
cout << "RESULT: " << label << "\t" << xmin << "\t" << ymin << "\t" << xmax
<< "\t" << ymax << "\t" << confidence << "\n";
rectangle(img, Point(xmin, ymin), Point(xmax, ymax), Scalar(0, 255, 0), 1,
1, 0);
}
