multi thread based multi windows issue based on DirectX11

My app case is that for multi cameras, the images of each camera will be processed,i.e, enhancement, and then displayed in a specific window. Each window is for each camera, and all windows will be processed simultaneously.

My idea is to suppose image processing and display will be executed on GPU (if single GPU possible), and use multi thread based method with DX11 or DX12, because I am a beginner for directx, so any possible solution for this case, thanks in advance.
