The smallest unit of a digital image is called:

• Bit
• Pixel
• Voxel
• Element

Which color space is primarily used for digital displays?

• CMYK
• RGB
• HSV
• LAB

An 8-bit grayscale image has how many intensity levels?

• 2
• 100
• 256
• 1024

What does RGB stand for?

• Red Green Blue
• Real Glossy Black
• Red Gold Brown
• Radial Grey Beam

The process of reducing detail in an image is known as:

• Sharpening
• Blurring/Smoothing
• Equalization
• Contrast

The Canny edge detector uses which technique to remove weak edges?

• Averaging
• Non-maximum suppression
• Histogram stretching
• Blurring

Harris Corner Detector identifies corners by looking for:

• Color changes
• Large intensity changes in all directions
• Straight lines
• Circle centers

Morphological 'Dilation' generally results in:

• Thinner objects
• Thicker/Expanded objects
• Blurry edges
• Smaller file size

Erosion' followed by 'Dilation' is a morphological operation called:

• Closing
• Opening
• Smoothing
• Thinning

What does the 'Hough Transform' detect in an image?

• Colors
• Shapes like lines and circles
• File metadata
• Brightness

What is the main advantage of Convolutional Neural Networks (CNNs) for CV?

• They are very small
• They automatically learn spatial hierarchies of features
• They don't need data
• They only work on text

In a CNN, the 'Pooling' layer is used to:

• Increase image size
• Reduce spatial dimensions/parameters
• Change colors
• Add noise

Which object detection model is known for 'You Only Look Once'?

• R-CNN
• YOLO
• SSD
• AlexNet

Semantic Segmentation' assigns a label to:

• The whole image
• Every individual pixel
• Only the center of objects
• The file name

What is the purpose of 'Transfer Learning'?

• Moving files between computers
• Using a pre-trained model on a new, related task
• Deleting old models
• Learning to code
