If you upload one of your images to a photo site and put a link to it in your question, then people would be able to give you more concrete answers.

Answer 1

[Andreas Goser]

This depends on whether your "rain" is more of a noise in the image or larger objects. With a bit of luck, you can use standard deblurring or image enhancement techniques - see the respective demos of the Image Processing Toolbix for that. If the object are larger, you need to spend the effort to detect them and remove them. You also have the challenge of what to use as background then. But try the "Correcting Nonuniform Illumination" demo with the rice grains to get some ideas.

Towel.

[Walter Roberson]

Too much danger of smudging the image, Jan. And unfortunately, the usual alternatives of highly pure alcohol tend to ruin anti-glare screens of CRTS or melt the plastic on LCD displays. It might be better to use a highly hydrophilic substance, such as a dusting of sodium metal.

Oil painting => towel

Whoops! The OP wrote "rain *in* image", but my answer concerns "rain *on* image". I assume I've overseen an important detail.

You sass that hoopy Jan Simon? There's a frood who really knows where his towel is.

@mu0: Sorry for this non-productive answer. It is not my intention to be offending. Please feel encouraged to add details to your question, e.g. a copy of the picture or a more exact description of the inputs and wanted outputs. "Remove rain" is too abstract, to be answered exactly - although Andreas' answer seems to be very valuable already. I suggest to read this also: http://www.mathworks.com/matlabcentral/answers/797-how-do-i-write-a-good-answer-for-matlab-answers

its ok.nevermind..i already got some codes for removing rain in image.but, the image becomes blurred. i tried to solve the blurred image with function 'deconvwnr'.but the worst image appears. i used also'unsharp'.still nothing happen to the image..help me plz

[Jan]

Please show us the code and explain any details. Most of all it is not getting clear, what "rain in an image" is: Do you mean a RGB image? Do you have rain drops on the lense or did you take a photo on a rainy day, but want to insert a sunny sky?

Please show us the code and explain any details. "used 'unsharp'. still nothing happen" is definitely not exact enough to have a chance to suggest imüprovements. It is still not getting clear, what "rain in an image" is: Do you mean a RGB image? Do you have rain drops on the lense or did you take a photo on a rainy day, but want to insert a sunny sky? Do you think it is possible to remove any kind of rain without getting a blurred image?

Please read and consider the thread about asking good questions. E.g. "plz" is understood as "I'm not interested in doing it by myself". Usually people are less motivated to invest time for helping, if a question looks sloppy.
