Ideas for video in video

Any tricks to perform video in video

Like a picture inside a picture?  Fairly easy.

For each image, use ImageToImage to insert the smaller image into the larger one.  You may need to resize the image using extract first.  Then display the image and repeat with the next frames.

Hi Bruce,

  When i use the imagetoimage  function I get  a blank image. Seems funny. When i tried the copy image function, it shows the copy of the image. Am I doing something too silly?

ImageToImage works perfect as Bruce suggested:

 

Post your VI if you have any troubles.

Hi Bruce,

  Please have a look at this section of the vi. your suggestion works fine for still images. I tried that before. But for real time videos, there's something I don't understand.

What exactly you can't understand?

Be sure that:

- both images are the same type (U8 or I16, etc)

- if both images are 16 bit, then they should have neraby same intensity  (because mapped to 8 bit for display)

- small image is really smaller than bigger one

- small image positioned not outside

- both cameras deliver nearby same frame rate. If not, it will be good idea to organize separate threads.

- check error output
