Dear everyone,

I have to develop a software which detect when a video is wrongly rotated (for example this one

We cannot assume things like there are/aren't people or there is/is not sky... I have been thinking about how to address this issue:

  • Analyse the global movement in the video using differences between frames and HOGH transform... But this one doesn't work very good on a static videos.
  • Try to analyse which kind of image is: people, landscape, city and then look for characteristic features of each situation...
  • Look for text ...

I am quite stuck in this task... Could give me your opinion to try to find the way to address this ?

Thank you so much!
