A Matlab code is written to remove rain successfully using Lo gradient minimization technique.
How to run??
1. Unzip and place the folder 'Rain Pixel' in the path of Matlab
2. Run Rain_Removal_GUI.m
3. Select an image from 'Bangalore Rain' folder. Next click on Remove Rain button & observe the results.
4. Next run Verify.m to verify the proposed technique using HOG+SVM approach
The code is based on my paper: https://www.researchgate.net/profile/Manu_Bn2/publication/295235499_Rain_Removal_From_Still_Images_Using_L0_Gradient_Minimization_Technique/links/56c847aa08ae96cdd06acb6f.pdf

Note: The method of rain detection is only approximate and is different than the one mentioned in the paper. Nevertheless gives highly satisfactory results.
Comments & suggestions are always welcome

Can anyone explain the mathematical model for detecting rain and the steps in matlab for detecting rain???
Use Matlab 2013, the latest version of Matlab have different gui functions. Hence the errors.
This project was done 3 years ago in Matlab 2013.

This error comes when I click on remove rain button. Please help me Manu...
One can use imshowpair command. I have alredy done the befor /after in the gui itself. Its there in verify.m also.
Might be nice to show a before/after example image pair. I think I see only rain in the one you've added.
