Easy thresholding based image segmentation The BLOB-Analysis license includes pylon vTools for typical thresholding based BLOB analysis tasks, such as identifying regions by their grey value range. The license includes three thresholding tools: absolute thresholding, auto thresholding (binary), and relative thresholding for dynamic thresholding relative to a mean image. In combination with the included additional pylon vTools for region morphology and object filtering, you can use the thresholding tools to identify and analyze regions, objects and structures with outstanding robustness, accuracy and performance. Pylon vTools are part of Basler's pylon Software Suite.
