Function Documentation

sb_project_change_type()

sb_t_err sb_project_change_type	(	const char *const	solution_file,
		const char *const	project_uuid,
		sb_t_project_type	project_type
	)

Change the project type.

The function changes the project type in the solution file.
It also updates the project type in all rtn files associated with images in sb_t_svl_par::project_path.
The function returns SB_ERR_DIR_NOT_EXIST if sb_t_svl_par::project_path is not an existing folder, and SB_ERR_STRING_EMPTY if it is an empty string.
When the project type is changed the training and all the analysis results will be lost, moreover some data is initialized, others are kept.
Regarding the parameters of the project the models number, their name and sb_t_par. collaborations "collaboration matrix" are always kept.
While, for image data, ROI analysis and labeling can be retained or lost.
The following table shows what happens when you change the project type.

Source project type	Destination project type	ROI analysis	Samples	ROI defects	Model size	Network
Retina	Surface	full image	/	empty	/	/
	Deep Surface	full image	/	empty	/	initialized if necessary
	Deep Cortex	/	/	/	/	initialized if necessary
Surface	Retina	full image	none	/	initialized	/
	Deep Surface	kept	/	kept	/	initialized if necessary
	Deep Cortex	/	/	/	/	initialized if necessary
Deep Surface	Retina	full image	none	/	initialized if necessary	/
	Surface	kept	/	kept	/	/
	Deep Cortex	/	/	/	/	initialized
Deep Cortex	Retina	full image	none	/	initialized if necessary	/
	Surface	full image	/	empty	/	/
	Deep Surface	full image	/	empty	/	initialized

Parameters

[in]	solution_file	Solution file name.
[in]	project_uuid	UUID of the project.
[in]	project_type	New project type.

Returns

If successful, returns SB_ERR_NONE. Otherwise, it returns an error code sb_t_err.

sb_project_check_trained()

sb_t_err sb_project_check_trained	(	SB_HANDLE	handle,
		const char *const	model_name,
		float	scale,
		int *const	is_trained
	)

Checks if the project is trained.

Usually, to check if a project is trained and the sb_project_detection function can be called, the function is called with model_name equal to NULL and scale equal to 0.
The function works in a slightly different way depending on the project type.
In case of a Surface project the model_name and scale parameters can be configured in 4 different ways explained below.

model_name	scale	Condition	is_trained
NULL	0
		All models are disabled	1
		All the enabled models and all their enabled scale levels are trained	1
		There is an enabled model with all scale levels disabled	1
		There is an enabled model with no scale levels	0
		There is an enabled model with an enabled scale level that is no trained	0
		The project has no models	0
!=NULL	>=1.0
		The model is disabled	1
		The model is enabled and the scale is disabled	1
		the specified combination model_name - scale has been trained	1
		the specified combination model_name - scale has not been trained	0
NULL	>=1.0
		All the enabled models that have the specified scale level are trained	1
		There is an enabled model with the specified scale level that is not trained	0
!=NULL	0
		The model is disabled	1
		The model is enabled and all the enabled scale levels are trained	1
		The model is enabled and all the scale levels are disabled	1
		The model is enabled and it has no scale levels	0
		The model is enabled and there is an enabled scale level that is no trained	0

In case of Retina, Deep Cortex or Deep Surface project type the parameter scale is not used, so the table can be simplified as the one below:

model_name	Condition	is_trained
NULL
	All models are disabled	1
	All the enabled models are trained	1
	The project has no models	0
!=NULL
	The model is disabled	1
	The model is enabled and it is trained	1
	The model is enabled but it isn't trained	0

Parameters

[in]	handle	Project Handle.
[in]	model_name	Name of the model to be checked. If the model_name is not found the function returns the error SB_ERR_MODEL_NOT_FOUND.
[in]	scale	Level scale to check. Used only by Surface projects. The permitted values are 0 and between SB_PAR_LEVEL_SCALE_MIN and SB_PAR_LEVEL_SCALE_MAX with steps of SB_PAR_LEVEL_SCALE_GRANULARITY, i.e. 1, 1.5, 2, 2.5 etc. If scale has no allowed value, the function returns the error SB_ERR_WRONG_PARAMETER. If the scale has an allowed value but it is not found the function returns the error SB_ERR_SCALE_NOT_FOUND.
[out]	is_trained	It is set to 1 or 0, see the tables above.

Returns

If successful, returns SB_ERR_NONE. Otherwise, it returns an error code sb_t_err.

sb_project_detection()

sb_t_err sb_project_detection	(	SB_HANDLE	handle,
		const sb_t_image *const	img,
		const sb_t_roi *const	roi,
		const sb_t_roi *const	roi_defects,
		const sb_t_samples *const	samples
	)

Detection function.

The function elaborates the image inside the ROI.
You should use the function sb_project_get_res to get the results.
Remember to call sb_roi_evaluate_bounding_box if the ROI is changed.
In case of Surface and Deep Surface projects the function also executes a blob analysis on the voting plane in order to cluster the defects areas. The funcion does the blob analyis if the parameter roi_defects is valorized or if the sb_t_par.surface_blob_analysis is set.
If you want to reset the statistic you should call the funcion sb_project_reset_stat before to call sb_project_detection .

Note

The function needs that the license be active and valid.

Parameters

[in]	handle	Project handle.
[in]	img	Pointer to the image. It is analyzed inside the ROI.
[in]	roi	Pointer of the ROI.
[in]	roi_defects	Pointer to the defects ROI. Is it used only with Surface and Deep Surface projects. The parameter can be NULL. In the case roi_defects is valorized, the function executes the blob analysis on the voting plane and does the following operation: compare the results with the ground truth or labeling in order to: evaluate the truth of the blobs (see sb_t_res) evaluate the truth plane. update the detection statistics. You should use the function sb_project_get_stat to get them.
[in]	samples	Pointer to the samples of the image that is the ground truth or labeling. It is used only with Retina and Deep Cortex projects. The parameter can be NULL. If samples if valorized, the function works in test mode and can perform the following operation: compare the results with the labeling in order to set the field truth (see sb_t_sample) of the samples in the results (see sb_t_res). evaluates the detection statistics. You should use the function sb_project_get_stat to get them. In case the parameter roi_defects is valorized than the function vote plane extracted in order to cluster the defects areas and compare them with the corresponding areas of the ground truth, thus providing a global statistic.

Returns

If successful, returns SB_ERR_NONE. Otherwise, it returns an error code sb_t_err.

[in]	solution_file	Filename of the solution where to save the project. If NULL the function uses the parameter solution_file of the function sb_project_load used to create the project.
[in]	mode	Saving mode of a project into a solution. SB_PROJECT_MODE_DETECTION_ONLY : this mode is used to reduce the size of the solution file. In this case the training data are saved but not the data necessary for an incremental svl. Then you can call the sb_project_detection function to process the images. Training will be done from scratch if sb_svl_run function is called. SB_PROJECT_MODE_DETECTION_AND_SVL : both the training data and the data necessary for an incremental svl are saved.

Returns

If successful, returns SB_ERR_NONE. Otherwise, it returns an error code sb_t_err.

sb_project_set_par()

sb_t_err sb_project_set_par	(	SB_HANDLE	handle,
		const sb_t_par *const	par
	)

Sets the parameters structure into the project handle.

The function can invalidate the training if some critical parameter is changed.
In the following the list for each project type:

• Retina
  • model size
  • model collaborations
• Surface
  • automatic choice of levels
  • level scale
  • model collaborations
• Deep Cortex
  • models
  • model collaborations
  • network type
  • features multiplier
• Deep Surface
  • models
  • model collaborations
  • network type
  • auto tiling
  • tile factor (only if auto tiling is disabled)
  • tiling scale (only if auto tiling is enabled)
  • features multiplier

You can call the function sb_project_get_par_changes_info to know which models will be invalidated in a subsequent call of the function sb_project_set_par.
The following table describe all the possible situations in which a model (Retina and Surface) or a level (Surface) or the SVL (Deep Cortex and Deep Surface) will be invalidated or not.

sb_project_set_scale_offset()

sb_t_err sb_project_set_scale_offset	(	SB_HANDLE	handle,
		sb_t_size_flt	scale_offset
	)

Sets in the project handle the scale offset used at detection time.

The scale offset give the possbility to the user to vary the scale used by sb_project_detection when auto tiling is enabled. It consists in a couple of positive values that is added to the sb_t_svl_dl_par.scale parameter in order to increase both horizontale and verticaly the actual scale used at detection time. Call this function may be useful when detection is performed over images at different resolution but at the same time is necessary to maintain fixed the number of tiles effectively used by the algorithm and the elaboration times. However, the usage by detection of a scale different from that used by SVL, may affect the results. Therefore it is not recommended to set sensitivity values higher than (1.0, 1.0)
It works only for Deep Surface projects.

Note

If high scale offset value is needed, try to re-evaluate the sb_t_svl_dl_par::scale parameter used for SVL.

Default

Default value is (0.0, 0.0).

Parameters

[in]	handle	The project handle
[in]	scale_offset	New value of scale offset to be set

Returns

If successful, returns SB_ERR_NONE. Otherwise, it returns an error code sb_t_err.

sb_project_set_sensitivity()

sb_t_err sb_project_set_sensitivity	(	SB_HANDLE	handle,
		const char *const	model_name,
		float	scale,
		float	sensitivity
	)

Sets the sensitivity of the detection in the project handle.

The sensitivity affects only the results of the detection and does not affect training in any way.

Parameters

[in]	handle	The project handle.
[in]	model_name	Name of the model to be set. If NULL all models will be set.
[in]	scale	Level / Scale value. If 0 all levels will be set. Used only by Surface projects.
[in]	sensitivity	New value of sensitivity to be set. The range of acceptable values is between -1 and 1 excluded. If the value is greater than 1 or less than -1, it is rounded to 1 and -1 respectively.

Returns

If successful, returns SB_ERR_NONE. Otherwise, it returns an error code sb_t_err.
