| float sb_t_blob::angle |
Rotation angle of the smaller rotated rectangle.
Corresponds to the rotation of the major axis.
The angle is measured clockwise with zero corresponding to the positive x-axis.
The angle value is between 0 and 180.
The parameter is evaluated only is sb_t_blob_par::blob_min_rot_rect is set to 1, otherwise the angle is set to zero.
If you don't have the sb_t_blob_par::blob_min_rot_rect parameter available but you want to know if the rotation angle has been calculated, you have to look at the sb_t_blob::m_xx and sb_t_blob::m_yy values, it is sufficient that one of the two is not null.
| sb_t_point* sb_t_blob::contour |
Pointer to the array of the points of the blob contour.
To make the sb_blobs_detection function return the contour of the blob you must to set sb_t_blob_par.blob_contour to 1.
| sb_t_point2d_f sb_t_blob::coord_min_rot_rect[4] |
Coordinates of the vertices of the smaller rotated rectangle.
If the parameter sb_t_blob_par::blob_min_rot_rect is set to 1 the coordinates are those of the minimum rotated rectangle, otherwise they are those of the unrotated bounding box.
| sb_t_blob_deleted sb_t_blob::deleted |
Blob is marked as deleted.
When parameter sb_t_blob_par::keep_deleted is set to a value different from 0, than the function sb_blobs_detection does not delete the blobs filtered due geometric restrictions, that is area and/or width and/or height out of limits, but leaves them in the list and sets the parameter deleted.
| float sb_t_blob::m_xx |
Moment of inertia about the x axis.
It is always positive.
The parameter is evaluated only is sb_t_blob_par::blob_min_rot_rect is set to 1.
| float sb_t_blob::m_xy |
Moment of inertia about the x and y axes.
It can be both positive and negative.n It is negative when the principal axis has a rotation greater than 90 degrees.
The parameter is evaluated only is sb_t_blob_par::blob_min_rot_rect is set to 1.
| float sb_t_blob::m_yy |
Moment of inertia about the y axis.
It is always positive.
The parameter is evaluated only is sb_t_blob_par::blob_min_rot_rect is set to 1.
| sb_t_rle sb_t_blob::rle |
Pointer to RLE buffer.
To make the sb_blobs_detection function return the rle of the blob you must set the parameter sb_t_blob_par.blob_rle to 1.
