Base class for detecting 90 objects of the COCO dataset.
Input is an image (cv:Mat).
Output is a struct of detection results, named TFSSDResult
.
Sample code :
Mat img = cv::imread("sample_tfssd.jpg");
auto tfssd = vitis::ai::TFSSD::create("ssd_resnet_50_fpn_coco_tf",true);
auto results = tfssd->run(img);
for(const auto &r : results.bboxes){
auto label = r.label;
auto x = r.x * img.cols;
auto y = r.y * img.rows;
auto width = r.width * img.cols;
auto height = r.height * img.rows;
auto score = r.score;
std::cout << "RESULT: " << label << "\t" << x << "\t" << y << "\t" <<
width
<< "\t" << height << "\t" << score << std::endl;
}
Display of the model results:
