01. Corners and Object Detection

Features alone and together

Now, you've seen examples of shape-based features, like corners, that can be extracted from images, but how can we actually uses the features to detect whole objects?

Well, let's think about an example we've seen of corner detection for an image of a mountain.

Say we want a way to detect this mountain in other images, too. A single corner will not be enough to identify this mountain in any other images, but, we can take a set of features that define the shape of this mountain, group them together into an array or vector, and then use that set of features to create a mountain detector!

In this lesson, you'll learn how to create feature vectors that can then be used to recognize different objects.
