Digital image correlation and tracking

Digital image correlation and tracking is a way for a computer to watch a video or look at a picture and understand how it changes over time. Imagine you are watching a video of a toy car moving across a room. Digital image correlation and tracking would allow the computer to follow the car as it moves and keep track of where it is in the image over time.

The computer does this by looking at the pixels in the images or video frames. Pixels are tiny dots that make up an image. The computer looks at each pixel and compares it to the pixels around it to see if it has moved or changed in any way. It then records this movement and uses it to track the object in the image or video.

Digital image correlation and tracking can be used in a lot of different ways. For example, it can be used to track the movement of athletes in a sports game, to measure the deformation of materials in engineering, or to monitor the growth of plants in agriculture.

In summary, digital image correlation and tracking is a way for a computer to watch and understand how things in an image or video move, using pixels to track changes over time.
