Segmentation

• You often want to break the picture (or film) into components.
• For example, in film, you want to see how objects move. You need to segment the film into objects, or perhaps you're only interested in one object.
• There are a range of techniques for doing this.
• A simple technique is a bounding box, sphere or, polygon. (Attention and moonwalking gorillas)
• If it's film, and you can match in smaller regions, you can use things that change together.
• So, if one area moves to the left, and another to the right, they are probably two separate segments.
• You can take advantage of machine learning techniques to segment areas.
