What is the primary purpose of intensity transformation functions?

• To change the resolution of an image

• To enhance the contrast or brightness of an image

• To perform image segmentation

• To reduce image noise

Which of the following is a commonly used intensity transformation function?

• Histogram equalization

• Edge detection

• Morphological transformation

• Image convolution

Histogram equalization is primarily used to:

• Improve the sharpness of an image

• Enhance the contrast of an image

• Reduce the size of an image

• Detect edges in an image

In histogram processing, the cumulative distribution function (CDF) is used to:

• Calculate the mean intensity

• Normalize the histogram

• Map intensity levels for histogram equalization

• Smooth the histogram

Spatial filtering is primarily used to:

• Enhance specific features in an image

• Change the image size

• Apply color transformations

• Increase the bit depth of an image

Which of the following best describes a convolution operation in spatial filtering?

• A process that scales the image

• A process that blurs the image

• A mathematical operation that combines two functions

• A method to change image format

What is the main goal of a smoothing spatial filter?

• To sharpen image edges

• To reduce noise in an image

• To enhance contrast

• To detect corners

Which of the following is a common smoothing filter?

• Sobel filter

• Laplacian filter

• Gaussian filter

• High-pass filter

Sharpening filters are designed to:

• Reduce the size of an image

• Enhance the edges and fine details

• Smooth out the image

• Convert an image to grayscale

Which filter is commonly used for sharpening images?

• Median filter

• Gaussian filter

• Laplacian filter

• Average filter
