Goals of segmentation - Group together similar-looking pixels for efficiency of further processing > simplify and / or change the representation of a image into something that is more meaningful and easier to analyze Major processes for segmenation - Separate image into coherent 'object' > Bottom-up : group tokens with similar features > Top-down : group tokens that likely belong to the same obj..

Parametric (global) warping - Transformation T is coordinate-changin machine : $p' = T(p)$ - What does it mean that $T$ is global? > is the same for any point $p$ > can be described by just a few numbers (parameters) - For linear transformations, we can represent T as a matrix $p' = Tp$ Common transformations - Translation - Rotation - Aspect - Affine - Perspective Scaling - Scaling a coordinate..
