Inspiration

As the festival of colour promotes the spirit of diversity it is important to see that no one is left behind in having fun. I see that Holi is most enjoyed because of the colours we can see, but what about the people who can't see colours... inspired by that I made an app to help those specially abled people to differentiate colours and enjoy the spirit of festival of colours

What it does

The app lets you draw at your own will and it saves the drawing in photo library of the phone. The main feature of the app is to take an image from the gallery and present it in such a way that a colour blind person can perceive and differentiate between the different colours present in the image.

How we built it

I first made a drawing board application which was pretty easy task. But for the filter to work I did read a lot of research papers to get an algorithm to change the the pixel in such a manner that it can be perceived by colour-blind people. For the filter to work I had to take the raw image pixel data in RGBA format the change each pixel data to LMS format , then apply the ** Daltonize algorithm** and then convert the new LMS pixel data to RGBA format

Challenges we ran into

The algorithm to manipulate pixel data in RGBA format was not present so I had to convert each pixel into LMS picture data format and then apply the algorithm and then again convert the LMS picture data to our RGBA format
