Hello Mr/Ms,
I want to use RNN network to get sequence of frames and output another sequence of key frames.
How can I achieve that purpose?
Thanks,

Hi Walter, My application is OCR for text in videos which is rotating horizontally or flipping vertically . I want to detect the frames with totally new text .
What are the optimum algorithm that I can use?

That is an algorithm question, not a MATLAB question. It is also a different algorithm question than was originally asked as key frame detection does not have much to do with ocr.

MATLAB has an ocr() function. You can train the underlying neural network with text in a variety of orientations.

Hello Walter,
I have sequence of frames for news caption images cropped from real news video
for example: 6 frames
  • Obama will visit Ger
  • will visit Germany
  • l visit Germany next
  • Visit Germany next week
  • ....text rotate....
  • He will sign contracts
The first and last one are unique (key frames)
This should be the output of the network.
How can I achieve that? What are the best algorithms to use?
Thanks

This is resource for asking questions about how MATLAB works, for helping debug existing code, for helping locate MATLAB functions with specific purpose like "weibel fitting". It is not a resource for researching what imafe processing or deep learning algorithms exist and their tradeoffs.
