Detailed Description

Visual registration between two signatures using features and geometry.

Extracts and matches features (Feature2D), then estimates motion with Vis/EstimationType (3D→3D, 3D→2D PnP, or 2D→2D epipolar). Supports RGB-D (CameraModel + depth), stereo (StereoCameraModel), optical flow, GMS, and optional Python matchers when built with Python support.

Can chain a child_ registration (e.g. RegistrationIcp in Registration::kTypeVisIcp). Feature-related Vis/ parameters are mapped to Kp/ for Feature2D::create().
