Android Question Image filter / color mapping

[yiankos1]

Hello my friends,
I built an image editing application and i got some good color mapping .png in order to apply them in photos. Does anyone knows how to apply these color mappings at photo's pixels?
Thank you for your time.
(i attach you a sample color mapping in order to understand what it is)

How exactly do you want to apply these colors? Do you want to greyscale the photo?

Good morning Erel,
1) I would like to apply filters like instagram's filters. I have all instagram's filters color mapping but I don't know how to apply them on photos. Here is github app using them: https://github.com/wuhaoyu1990/MagicCamera, maybe will help you out in order to understand what i want.
(By the way it is great app/lib to be ported in b4a)

2) I would like your opinion about photo filtering. For example, i create with photoshop some filter masks(custom settings with alpha in order to be applied above my photo), what's the best solution to be applied? I tried firstly to draw photo in canvas and after that draw the mask. It's working fine! I saw at imageProcessing library that there is blend option, which does the same. I saw openGL has something like this but theres is no option to be saved.

Thank you for your time.

Thank you for your answer, but I would like to inform you that these two libs/app are different.
Thank you for your time.
