Expand description

Returns a point in normalized coordinate space within a spedified regioin of interest (roi) that is projected from a point in a image coordinates

Parameter imagePoint: The point in image coordinate space.

Parameter imageWidth: The pixel width of the image.

Parameter imageHeight: The pixel height of the image.

Parameter roi: The region of interest on which the normalized point will based on.

Returns: the point in normalized coordinates in relation to the region of interest.
