| sb_t_range sb_t_svl_dl_par_perturbation::angle_range |
Angular range, in degrees, for random rotation.
Set minimum and maximum values equal if you don't want random rotation.
Minimum angle must be less than or equal that maximum angle.
The range of values for both the minimum angle and the maximum angle is [-180; 180] degrees.
| float sb_t_svl_dl_par_perturbation::delta_brightness |
Maximum delta of brightness.
The admitted value is a percentage in the range [SB_SVL_DL_PERTURBATION_DELTA_BRIGHTNESS_MIN, SB_SVL_DL_PERTURBATION_DELTA_BRIGHTNESS_MAX] and determines the maximum brightness offset to apply to the pixels of the image. At each epoch, an image is perturbated by a brightness variation randomly extracted from the interval [-delta_brightness*255, delta_brightness*255]. 0 Means disabled
| float sb_t_svl_dl_par_perturbation::delta_scale |
Maximum variation for image scaling.
The admitted value is in the range [SB_SVL_DL_PERTURBATION_SCALE_MIN, SB_SVL_DL_PERTURBATION_SCALE_MAX] and determines the maximum positive and negative scale offset to apply to resize the image. At each epoch, an image is perturbated by a scale factor randomly extracted from the interval [1-delta_scale, 1+delta_scale].
0 Means disabled.

| float sb_t_svl_dl_par_perturbation::shift_horizontal |
Maximum shift along x-axis.
The admitted value is a percentage in the range [SB_SVL_DL_PERTURBATION_SHIFT_MIN, SB_SVL_DL_PERTURBATION_SHIFT_MAX] and corresponds to the maximum horizontal shift to be applied to the image. At each epoch, an image is randomly shifted by factor lower/equal than the maximum one.
0 Means disabled
| float sb_t_svl_dl_par_perturbation::shift_vertical |
Maximum shift along y-axis.
The admitted value is a percentage in the range [SB_SVL_DL_PERTURBATION_SHIFT_MIN, SB_SVL_DL_PERTURBATION_SHIFT_MAX] and corresponds to the maximum vertical shift to be applied to the image. At each epoch, an image is randomly shifted by a factor lower/equal than the maximum one.
0 Means disabled
| float sb_t_svl_dl_par_perturbation::stretch_contrast |
Maximum variation for histogram stretching.
The admitted value is a percentage in the range [SB_SVL_DL_PERTURBATION_STRETCH_CONTRAST_MIN, SB_SVL_DL_PERTURBATION_STRETCH_CONTRAST_MAX] and determines the maximum stretch/compression to apply to the pixel histogram of the image. At each epoch, an image is perturbated by a random contrast variation. 0 Means disabled.
