Geometry estimation functions

imcui.ui.geometry

Geometry estimation functions for computing transformation matrices between matched points.

Functions

compute_geometry

Compute geometric transformation between matched keypoints.

from imcui.ui import compute_geometry

H, mask = compute_geometry(
    kp0, kp1, matches,
    geometry_type="homography",
    ransac_method="CV2_USAC_MAGSAC"
)

Parameters:

Parameter	Type	Description
kp0	np.ndarray	Keypoints from first image, shape (N, 2)
kp1	np.ndarray	Keypoints from second image, shape (M, 2)
matches	np.ndarray	Matched point pairs, shape (K, 2)
geometry_type	str	Geometry type: “homography”, “fundamental”, “essential”
ransac_method	str	RANSAC method: “RANSAC”, “CV2_USAC_MAGSAC”, “LMEDS”

Returns:

• H: Transformation matrix (3x3 for homography/fundamental)
• mask: Boolean mask indicating inliers
