Field Documentation

◆ blob_contour

int sb_t_blob_par::blob_contour

Set to 1 if you want the contour of each blob.

See also: sb_t_blob::contour

Definition at line 8587 of file sb.h.

◆ blob_distance_mode

sb_t_blob_distance_mode sb_t_blob_par::blob_distance_mode

Selection of the algorithm for calculating the distance between blobs.

The distance between blobs is used only for the merge operation.

Definition at line 8597 of file sb.h.

◆ blob_min_rot_rect

int sb_t_blob_par::blob_min_rot_rect

For each blob it enables the calculation of the smaller rotated rectangle containing the blob.

Requires the sb_t_blob_par::blob_rle parameter to be enabled.

Definition at line 8592 of file sb.h.

◆ blob_rle

int sb_t_blob_par::blob_rle

Set to 1 if you want the rle of each blob.

See also: sb_t_blob::rle

Definition at line 8582 of file sb.h.

◆ lut

unsigned char sb_t_blob_par::lut[256]

Lut of gray levels used to find the blobs.

If the value lut[x] is 0, then the corresponding gray level x is not used. If the value lut[x] is greater than 0, then the corresponding gray level x is used. Moreover, a blob is composed of all the pixels that have the same value of the lut. The value of the lut is written in parameter sb_t_blob::lut . The blobs with different value of the lut are manage in a indipendent mode. So using different values of the lut is like doing more blob analysis with the same call of the sb_blobs_detection function.

Definition at line 8573 of file sb.h.

◆ merge_distance

int sb_t_blob_par::merge_distance

Blobs with a distance inferior or equal to the value are merged together.

Set to a negative value to disable merging. Value in pixel.
Only blob with the same value of the lut are merged togheter.
