Can someone give some hint on why mine demosaic.ppm look like this?

It's difficult to tell, since there are a variety of places where you can introduce bugs. One common case is related to doing integer division (e.g., between two unsigned chars) when you really need to divide two floats.

Thanks! I tried that. But I still got the same colour image.Is there a reason why the particular colour of the image? Am I missing anything in the interpolation calculation that leads to this colours? I have no clue what I might have done wrong.

did you figure this out? I'm getting a similar image using the stuff that was taught in lecture.
