Popular sides of video processing
Hello,
I want to know what is actual subjects in video processing that haven't been fully researched and need to be researched. What video filters you want to use, that don't exist yet? I really need your opinion! Best regards, slavanap. |

- effective removal of analog artefacts (like rainbows and crawls in composite video)
- motion estimation and interpolation that works as well as a human brain works. especially at low frame-rates where there's no falling back on frame blending. - noise reduction that works as well as a brain works (which is to say the brain can't be fooled by the right signals...) - stenography, and removal of invisible watermarking (this is more applicable to audio - see the "cinavia" thread in the decrypting forum) - anything to do with interlace is exceedingly unpopular, but good handling of interlace is necessary.

I had an idea for this where I thought maybe the algorithm could look at the relative bluriness of neighboring pixels to get an idea of that pixel's depth (because the optics of a camera progressively blur objects further away and closer to the focal point). However, after reading several technical papers, I've come to the conclusion that it's just not enough. (Truthfully, I didn't understand most of the math, but you don't have to in order to get the point that more is needed to determine depth with any kind of accuracy and precision.) |

And about removing logos: http://compression.ru/video/logo_removal/index_en.html There are several techniques for removing transparent logos more efficiently, but I'm not sure, have them been realized or not. It fits. Last edited by slavanap; 13th June 2011 at 15:38. |

This subject also fits, thank you. (I'm looking for a subject for free filter I'm going to develop) Last edited by slavanap; 13th June 2011 at 15:51. |
