Morphological Operations
1. What is the small template used to define the shape and size of a morphological operation called?
2. Which morphological operation generally enlarges or expands foreground objects in a binary image?
3. Which operation is defined by first applying erosion and then applying dilation with the same structuring element?
4. Which morphological operation is most appropriate for eliminating small holes and filling gaps in the boundary of foreground objects?
5. If the size of the structuring element is increased, which factor is most directly affected in a morphological operation?
6. In grayscale morphological processing, which operation determines the output pixel value by taking the maximum of the neighbourhood pixel values?
7. A narrow connection joins two large foreground regions in a binary image. Which operation is most appropriate for breaking such a connection when the structuring element is suitably chosen?
8. Why is the shape of a structuring element selected according to the geometric features of interest in an image?
9. Which statement best describes the relationship between opening and closing?
