摘要：

Typical images are scalar fields on the Euclidean plane, or surfaces in ''two-plus-one-dimensional'' space. We study the invariant image structure with respect to arbitrary, monotonic and affine intensity transformations. Invariants are useful features for recognition or registration problems. We correct (common) mistaken notions concerning topographical ridges and courses. Results are relevant in a much wider context.
