     Estimated depth maps

It is composed out of

• Image upscaler module
• Segmentation module
• Graph Cut Optimiation module

Output views images are selected from set of input view images, according to configuration parameters of currect run. Output views images are feed into a segmentation module which provides segment index map for each of the output view. Input views images are upscaled and along with images of the output views and segment index maps for the output views are feed into a Graph Cut optimization module. Graph cut optimization module calculates depth maps for all of the selected output views.
