Object detection steps

One-Stage

  1. Extracts feature on all area of image, classify the objects,

    localize bounding-box

Two-Stage

  1. Generates category-independent region proposals,

    extracts feature vector from each region proposal

  2. Classify the objects, precisely bounding-box prediction (NMS)

Performance table

FPS(Speed) index is related to the hardware spec(e.g. CPU, GPU, RAM, etc), so it is hard to make an equal comparison. The solution is to measure the performance of all models on hardware with equivalent specifications, but it is very difficult and time consuming.
