I understand you want to add points to an existing image . You can do it in two ways.

1. Using MarkerInserter object from Computer Vision Toolbox. Refer here for details.

2. Next method is to use "plot". You do not need any additional toolbox to achieve this.

>> image(magic(5))
>> hold on;
>> plot(1,2,'r.','MarkerSize',20);

As of R2013a vision.MarkerInserter has been deprecated. Please use the insertMarker function instead.
