1. What does the distance relational approach focus on in region analysis?
a) Region properties
b) External points
c) Spatial moments
d) Mixed spatial gray-level moments
Answer: b) External points
Explanation: The distance relational approach in region analysis focuses on examining the relationships between external points of a region and other features within the image.
2. Which framework for matching involves organizing models in a database?
a) Distance relational approach
b) Ordered structural matching
c) View class matching
d) Models database organization
Answer: d) Models database organization
Explanation: In the context of matching frameworks, organizing models in a database is a crucial aspect of the Models database organization framework.
3. What aspect of boundary analysis involves analyzing signature properties?
a) Region properties
b) External points
c) Spatial moments
d) Signature properties
Answer: d) Signature properties
Explanation: Boundary analysis involves examining signature properties, which describe characteristics such as curvature and orientation along the boundary of a region.
4. In region analysis, what is examined to derive mixed spatial gray-level moments?
a) Region properties
b) External points
c) Spatial moments
d) Boundary analysis
Answer: c) Spatial moments
Explanation: Mixed spatial gray-level moments in region analysis are derived by analyzing spatial moments, which capture the distribution of intensity values within a region.
5. Which approach in general frame works for matching emphasizes the order of structural elements?
a) Distance relational approach
b) Ordered structural matching
c) View class matching
d) Models database organization
Answer: b) Ordered structural matching
Explanation: Ordered structural matching in general frame works for matching emphasizes the order of structural elements within objects or patterns being compared.
6. What does view class matching focus on in general frame works for matching?
a) Region properties
b) External points
c) Spatial moments
d) Different views of objects
Answer: d) Different views of objects
Explanation: View class matching in general frame works for matching concentrates on comparing and recognizing objects from different perspectives or views.
7. Which property is not typically associated with boundary analysis?
a) Signature properties
b) Shape numbers
c) Spatial moments
d) Curvature analysis
Answer: c) Spatial moments
Explanation: Boundary analysis usually does not involve spatial moments, which are more associated with region analysis rather than boundary analysis.
8. What is the primary focus of region analysis?
a) Analyzing external points
b) Describing boundary properties
c) Examining spatial moments
d) Understanding region properties
Answer: d) Understanding region properties
Explanation: Region analysis primarily focuses on understanding and characterizing the properties and attributes of regions within an image.
9. Which approach in region analysis examines the relationships between points inside and outside a region?
a) Region properties
b) External points
c) Spatial moments
d) Mixed spatial gray-level moments
Answer: b) External points
Explanation: The external points approach in region analysis involves examining the spatial relationships between points inside and outside a region to understand its properties.
10. What does the distance relational approach emphasize in region analysis?
a) Analyzing external points
b) Describing boundary properties
c) Examining spatial moments
d) Evaluating mixed spatial gray-level moments
Answer: a) Analyzing external points
Explanation: The distance relational approach in region analysis emphasizes analyzing the spatial relationships between external points of a region and other features within the image to characterize the region.
