所有已实现的接口:

Sequenceable
```
public class CvRect
extends Object
implements Sequenceable
```
Describes the rectangle area of images.
The rectangle area has four coordinates (in pixels): vertical coordinate of the upper boundary, horizontal coordinate of the left boundary, vertical coordinate of the lower boundary, and horizontal coordinate of the right boundary.
