What is the main goal of image segmentation?
To enhance image brightness
To divide an image into parts that correlate with real-world objects
To compress image data
To convert images to grayscale
What is complete segmentation?
Regions that overlap with each other
A method of image compression
A set of disjoint regions corresponding uniquely to objects
An image with no segmentation
Which of the following is a characteristic used in edge detection?
File size
Image resolution
Brightness
Color depth
What is the simplest segmentation process mentioned?
Edge-based segmentation
Adaptive thresholding
Region-based segmentation
Gray level thresholding
What does adaptive thresholding do?
Uses a single global threshold for the entire image
Changes the threshold dynamically based on local characteristics
Ignores local variations in the image
Only works with binary images
What is the Chow and Kaneko approach used for?
Detecting edges in images
Enhancing image contrast
Finding the optimal threshold for each sub-image
Creating a binary image
What is the purpose of the Otsu method?
To apply adaptive thresholding
To select an optimal threshold for image segmentation
To reduce image noise
To enhance image colors
What is a drawback of the Otsu method?
It requires manual threshold selection
It is computationally expensive
It works well with variable illumination
It assumes the histogram is bimodal
What is the result of multithresholding?
A color image
A binary image
A grayscale image
An image with multiple gray levels
What is the main challenge in achieving complete segmentation of complex scenes?
High computational cost
Ambiguity in image data
Lack of available algorithms
Insufficient image resolution
