What kind of curve? With 3 points, you can do a second order curve or first order line. Do you want a parabola, a circle, or a line? Did you try passing the points into polyfit(), or see the FAQ?

It's in the FAQ. Did you click on the link I gave you? The code is right there to fit a circle. After that you can decide where to split the circle into halves. Where to you think you want to do that?

What kind of interpolation are you going to use? Is your output image also going to be logical? If so, I assume you are using Nearest Neighbor?
