## Better Representation for ImagesBeymer, Jones, Poggio, etc.

- I New = I + T(M)a is restrictive
- Only captures a small range of translations/rotations/etc.

- What about shifting the pixels themselves?
IT = T( I, Dx, Dy)IT (x, y) = I(x - Dx, y - Dy)

- More generally:
INew (x, y) = I(x - fx(x,y), y - fy(x,y)) - or -INew (x, y; a) = I(x - a fx(x,y), y - a fy(x,y))
