We have now obtained three approximations of the data This gets my 5. That is to say, to determine a, b, and c, where y = ax2 + bx + c. Having determined a, b, and c, I would also need a value for R-squared (the coefficient of determination). The goal of this problem is to find the cubic polynomial y = c1 + c2x + c3x2 + c4x3 that gives the best least square fit to the data. My plan is to iterate through regions of data and perform a surface-fit, look at the error, see if it's a continuous surface (which would probably indicate a feature in the image).
