How to install TensorFlow 2.0 on UbuntuĮither tutorial will help you configure your system with all the necessary software for this blog post in a convenient Python virtual environment.To configure your system for this tutorial, I recommend following either of these tutorials: In the rest of this tutorial, you’ll learn how to implement region proposal object detection. The amount of accuracy lost is minimal, if any.It is faster than exhaustively examining every scale/location of the input image.Region proposal algorithms tend to be far more efficient than the traditional object detection techniques of image pyramids and sliding windows because: Let’s apply our more computationally expensive classifier to determine what’s actually in this region. Hey, this looks like an interesting region of the input image. Instead, region proposal methods simply tell us: Notice how I’ve italicized “could” in the sentence above the image - keep in mind that region proposal algorithms have no idea if a given region does in fact contain an object. Figure 2: In this tutorial, we will learn how to use Selective Search region proposals to perform object detection with OpenCV, Keras, and TensorFlow.
