EmguCV DNN使用 YOLOv3 進行物件偵測

沒想到OpenCV 3.4.2版以上已經開始支援YOLOv3

而目前EmguCV也已經更新到4.3.0版本

以C#開發者來說，這比編譯darknet wrapper還來的更方便啊!!

就來看看怎麼在EmguCV中使用YOLOv3吧!!

Face Recognition with FaceNet

Google在2015年提出透過深度學習的方式處理人臉辨識的系統FaceNet

該論文的連結可參考此處

很快的這個方法就席捲了人臉辨識的應用

許多過去傳統的人臉辨識演算法都不敵FaceNet

在論文中提到，其採用LFW人臉資料庫進行benchmark

並以99.63%的準確率，打破了過去的紀錄

而在YouTubeFaces人臉資料庫也進行了測試

依舊創下高達95.12%的準確率

若是想要研究人臉辨識，一定要認識FaceNet

Face Detection with EmguCV Haar and DNN

過去在EmguCV (OpenCV)中

人臉偵測是常用且簡單的功能

過去都是使用Haar cascades的方法來實作

但在OpenCV 3.3.1之後，提供了DNN深度學習的人臉偵測方法

來比較看看吧!!

CPU vs GPU、YOLO-darknet vs tensorflow效能比較

既然手邊剛好有三張不同的顯卡：GTX 1080Ti、RTX 2070、RTX 2080

也實作了YOLO-darknet與tensorflow 的 C# wrapper

那就來測試一下運算效能吧!
