Release 1.9.4

(release date: 19 November 2021)

Release 1.9.3

(release date: 16 June 2021)

(release date: 16 April 2021)

Release 1.9.0

(release date: 13 January 2021)

Release 1.8.4

(release date: 30 June 2020)

  • Bug fix
    1. Surface SVL: a defect near the edge of the analysis roi with an optional part outside the analysis roi could be considered Out Of Roi.
    2. Retina SVL: if a svl was made without putting a sample, mandatory or optional, it happened that, even adding the sample, the training remained corrupt and to unlock the situation it was necessary to reset the svl.

Release 1.8.3

(release date: 16 June 2020)

  • Bug fix
    1. SVL: with both optional and mandatory samples of the same model the svl could end with the error SB_ERR_INTERNAL .
    2. Surface SVL: it could happen that a defect close to but outside the roi generated a sample of defect inside the roi, therefore in the background. This sample created serious training problems.
    3. Surface SVL: it could happen that a defect close but outside the ROI was not counted as Out Of Roi.
    4. Surface SVL: a defect near the edge of the analysis roi with an optional part outside the analysis roi could be considered Out Of Roi.

Release 1.8.1

(release date: 2 April 2020)

  • New features
    1. SVL has been made faster.
    2. Feature 3A has also been enable for grayscale image
    3. Feature 3B, 3C, 3D, 3E have been added
    4. On Linux system the image resize with bilinear interpolation has been added
    5. The vote plane border has been reduced
    6. Surface SVL: SVL works with only warped2roi lut
  • Bug fix
    1. sb_project_get_res : no more error if the roi used for detection has a bounding box with a width/height less than 4. In this case surface planes are not allocated
    2. sb_roi_create : the width_step of the image was not aligned to 4 bytes.
    3. Retina: the weight of the samples was made independent of the position of the analysis ROI
    4. Surface: the quantization of the values close to zero in the voting plan has been corrected. Negative values close to zero are set to 127 instead of 128.
    5. Surface: for scale greater than 1 the value of the pixel of vote plane was made independent of the position of the analysis ROI.
    6. Surface SVL: fixed svl issues in case of too little roi on last svl image and low free memory condition
    7. Surface: fixed incorrect expansion of 3 pixels at the bottom of the voting plan.
    8. sb_surface_blob_analysis considers the defect starting from values greater or equal than 0 instead of greater than 0.
    9. Surface: sb_project_detection didn't consider the value set with function sb_set_circular_image_width
    10. Surface SVL: incremental SVL has been fixed with scale greater than 1x and warping enabled
    11. Surface SVL: SVL worked differently if the same image dataset was passed in RGB format instead of BGR
    12. sb_image_save : fixed false error of memory detected by sb_malloc_check_memory_leak in case of saving of png images
    13. sb_svl_run : the memory leak was fixed if the function was called more than once
    14. sb_svl_run : the function crashes when the project is loaded with SB_PROJECT_LOAD_DETECTION_ONLY
    15. If there are multiple models, sb_svl_run can return the SB_ERR_WRONG_PARAMETER error in the following case: the size of some models has been changed and the labeling of other models has been corrected because the sample has not been inserted in one or more points.
    16. SVL: error management of samples with same UUID
    17. sb_license_get_info : in case of difficult network connection it could happen that the function set sb_t_license_module::err with generic error SB_ERR_LICENSE instead of SB_ERR_LICENSE_FILE . In this case the SB GUI did not start the license tutorial.

    3. Surface SVL: it could happen that a defect close but outside the ROI was not counted as Out Of Roi.
    4. Surface SVL: a defect near the edge of the analysis roi with an optional part outside the analysis roi could be considered Out Of Roi.
    5. sb_project_save returned error with 64 models.
    6. Surface SVL: correct repeatibility of training in case of different OR defects
    7. Surface SVL: with warped2roi lut, the samples that have the same coordinates on the original image as others already taken are discarded
    8. Surface SVL: the area of the image labeled as defect for a model is ignored by the collaborating models during the training
    9. Retina SVL: if a svl was made without putting a sample, mandatory or optional, it happened that, even adding the sample, the training remained corrupt and to unlock the situation it was necessary to reset the svl.
