Module detect 

Corner detection utilities built on top of the dense ChESS response map.

Functions

detect_corners_from_response

Core detector: run NMS + refinement on an existing response map.

detect_corners_from_response_with_refiner

Detector variant that accepts a user-provided refiner implementation.

detect_peaks_from_response

Stage 1 of ChESS detection: threshold + NMS + cluster-filter on the response map.

detect_peaks_from_response_with_refine_radius

Stage 1 of ChESS detection: same as detect_peaks_from_response but extends the border margin by refine_radius extra pixels so that an image-domain refiner with the given patch half-width can safely operate on every accepted peak.

find_corners_u8

Compute corners starting from an 8-bit grayscale image.

find_corners_u8_with_refiner

Compute corners starting from an 8-bit grayscale image using a custom refiner.

merge_corners_simple

Merge corners within a given radius, keeping the strongest response.

refine_corners_on_image

Stage 2 of detection: image-domain subpixel refinement.
