Blob makes possible teach-in blobs based the following parameters (procedure for blob analysis):
• Thresholds for grayscale values (MeanGrayValue)
• Blob shape (morphology)
• Thresholds for size (AreaMin/Max) (rough reduction)
• Selection according shape and fitting
• Calculate the geometric features.Function description
