void features_RoIs_write(FILE *f, const int frame, const RoI_basic_t *RoIs_basic, const RoI_magn_t *RoIs_magn, const RoI_elli_t *RoIs_elli, const size_t n_RoIs, const vec_track_t tracks, uint8_t hexa_float, const unsigned age)

Print a table of RoIs.

See also

RoI_elli_t for more explanations about the features.

Parameters

f – File descriptor (write mode).
frame – Frame id corresponding to the RoIs.
RoIs_basic – Basic features.
RoIs_magn – Magnitude features (can be NULL).
RoIs_elli – Ellipse features (can be NULL).
n_RoIs – Number of connected-components (= number of RoIs) in the 2D array of labels.
tracks – Vector of tracks. It enables to match RoIs with corresponding track in the table of RoIs. Can be NULL, then the corresponding tracks are not shown.
hexa_float – A boolean to print float numbers in hexadecimal.
age – 0 if frame is the current frame, 1 if frame is the \(t - 1\) frame. This is mandatory to find the corresponding track (if any). If tracks == NULL then this argument is useless.
