Create an overlay image mask

Hi,

I am doing my project in labVIEW 2017. I am working on slide scanner development project to automate traditional microscopic slides to digital slides, which can be viewed on computer screen. As part of it I have to acquire many images of single slide which comes with overlapping. Images are acquired using camera attached to microscope. Images are stored in a folder . So I have to create a labview program to generate final joined image of a single slide from many  images of slides taken with overlap.

 

Actually I tried to do labVIEW program to join 2 images which are having some overlap. (join images along overlaping area) But I wasn't successful.

 

I would like to know how to do below described process in labview. I tried to do but it didn't worked out.

Form a mask that matches the pixels you to overlay from image2 onto image1 Use this mask to zero out all pixels in image 1 that are covered by the mask effectively erasing the space we will place image 2.then use inverse of the mask on image 2 so that it consists only of pixels you want to add. Now add these 2 sub images, effectively placing image 2 onto hole created on image1

 

I want to know how to automatically have control on overlapping areas in images.

 

Thanks
