Module chess 

ChESS detector pipeline.

Implements the corner detector described in Bennett & Lasenby, ChESS: A Fast and Accurate Chessboard Corner Detector (CVIU 2014):

1. response::chess_response_u8 computes a dense response map from a 16-sample ring around each pixel.
2. detect::detect_corners_from_response thresholds the map, runs non-maximum suppression, and rejects isolated peaks.
3. The detector candidate is then handed to a refiner from crate::refine and an orientation fit from crate::orientation to produce a final crate::detect::CornerDescriptor.

Modules

detect

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

response

Dense ChESS response computation for 8-bit grayscale inputs.

ring

Canonical 16-sample rings used by the ChESS detector.
