overlay destroys live image

[neelesh314]

I want to print text at certain positions on image captured using Vision Acquisition. I am thresholding the image to detect objects and then running overlay text in a loop to display the text beneath each object. At the end, I am getting the text written below the objects but the thresholded objects disappear ( the red markings). Why is this happening?

Could you please share your code...?

Threshold result - does it go into the same image as original? You should copy image to a separate buffer for processing and display overlay on original image.
