Overview
C structure is here. typedef struct CvSURFPoint { CvPoint2D32f pt; // position of the feature within the image int laplacian; // -1, 0 or +1. sign of the laplacian at the point. // can be used to speedup feature comparison // (normally features with laplacians of different // signs can not match) int size; // size of the feature float dir; // orientation of the feature: 0..360 degrees float hessian; // value of the hessian (can be used to // approximately estimate the feature strengths) } CvSURFPoint;
