Shape Feature rectangularity

• Blob analysis is an important method for many application areas
• One important step is here the selection of relevant regions after the segmentation
• Typical standard shapes besides circles and ellipses are rectangles
• Classical shape features like roundness, circularity, or compactness are not appropriate to select rectangles

• HALCON 7.1 offers a new feature especially designed for the selection and evaluation of rectangles
