Object Detection Landscape

Blog: The Object Detection Landscape: Accuracy vs Runtime

R-CNN, Fast R-CNN, Faster R-CNN

Blog: 目標檢測

  • R-CNN首先使用Selective search提取region proposals（候選框）；然後用Deep Net（Conv layers）進行特徵提取；最後對候選框類別分別採用SVM進行類別分類，採用迴歸對bounding box進行調整。其中每一步都是獨立的。
  • Fast R-CNN在R-CNN的基礎上，提出了多任務損失(Multi-task Loss), 將分類和bounding box迴歸作爲一個整體任務進行學習；另外，通過ROI Projection可以將Selective Search提取出的ROI區域（即：候選框Region Proposals）映射到原始圖像對應的Feature Map上，減少了計算量和存儲量，極大的提高了訓練速度和測試速度。
  • Faster R-CNN則是在Fast R-CNN的基礎上，提出了RPN網絡用來生成Region Proposals。通過網絡共享將提取候選框與目標檢測結合成一個整體進行訓練，替換了Fast R-CNN中使用Selective Search進行提取候選框的方法，提高了測試過程的速度。

Blog: [物件偵測] S3: Faster R-CNN 簡介

  • RPN是一個要提出proposals的小model，而這個小model需要我們先訂出不同尺度、比例的proposal的邊界匡的雛形。而這些雛形就叫做anchor。

  • RPN的上路是負責判斷anchor之中有無包含物體的機率，因此，1×1的卷積深度就是9種anchor，乘上有無2種情況，得18。而下路則是負責判斷anchor的x, y, w, h與ground truth的偏差量(offsets)，因此9種anchor，乘上4個偏差量(dx, dy, dw, dh)，得卷積深度為36。
