What type of filter is suitable to remove the luminosity of rain in this picture?
Keep follow two steps:
1. Detect the the raindrop on image => use threshold algorithm (because the raindrop is lighter than others, so threshold algorithm is the simplest).
2. Use any inpainting algorthms to remove the above detected regions (example Mumford-Shah).
You can try anisotropic diffusion!
Dear Nor Atikah Abu Bakar,
You can use YCbCr color space for this work. YCbCr color space separate luminance from chromatic. Y is luminance component, Cb and Cr are chromatic components.
try morphological tophat transform
Here I attach my result image after process of image.from this I don't know how to coding the calculate the rain distribution to get the percentage of raindrops image. thanks you for any advance
