Perspective transformation code

[r-213]

I see the page includes a description on carrying out perspective transformation of the facade/window but I can't find that in the code. Can you please let us know where this could be located?

Thanks

The one mentioned in this section. What code was used to straighten the window image?

[lck1201]

oh..yes, it's Homograph Transform. you can find code everywhere.

Thank you- is there a particular reference you can share? Also did you have to select the 4 control points manually? I ask as in the façade data set you are using there are multiple viewing angles, how is this accounted for (or automated)?
