how to de-noise a underwater video?

asked 2013-11-27 22:51:24 -0600

hi friends,

I am very new to opencv. I am using c++ with OpenCV for underwater video processing. I have added different types of noises (Gaussian, salt&pepper) to a video(mp4) using MATLAB. Now i want to remove the noise component in openCV (c++). any info or source code is appreciated.

The very popular and powerful "non local means" Denoising Algorithm has found its way into openCV. It is documented here:

http://docs.opencv.org/modules/photo/doc/denoising.html

If processing time is a concern, I would also try the billateral filter in the category mentioned above.

You can see OpenCV Documentation about smoothing and filtering here, and if you want create your own filter see documarntion about Making your own linear filters using OpnCV. You can find OpenCV API Reference about the filter here.
