In machine vision applications, an algorithm is applied within a region in an image (512 by 480 pixels) so that it operates on pixels within this region to obtain an output. This region within the image is called REGION OF INTEREST or ROI. The ROI provides a bounding box within which all of the operations on pixels are performed. The ROI can be specified as the entire or partial image. If the ROI is partial image, the computational time is fast due to less number of pixels. The ROI bounding box is represented by starting row position (n), starting column position (y), height (high) and width (wide).
