HSV

RGB

YUV

2. Bayer filter is a color pattern installed in front of the image sensor to record colored image. *

True

False

3. How many channels grayscale images have? *

4. Choose all correct statements about intrinsic parameters: *

They can be estimated using the checkerboard calibration procedure

Intrinsic parameters are same for each camera

They include information like focal length, skew factor and optical centers

They might change if camera has been moved

Required

5. Choose all correct statements about extrinsic parameters: *

They correspond to rotation and translation vectors

They include information about optical centers of camera

They denote the coordinate system transformations from 3D world coordinates to 3D camera coordinates

They describe the pose of the camera in the world

Required

6. CMOS sensor is responsible for: *

Controlling shutter speed

Regulating aperture size

Controlling white balance

Converting light to electrical signals

7. Camera calibration is required to get good estimation of the camera parameters. *

True

False

8. Choose all methods of image segmentation: *

Thresholding

Edge detection

Clustering

Required

9. Choose correct statements about CNN? *

CNN mantains the spatial relationship between input pixels

CNN learns basic edge and color information in the first layers

CNN is resistant to random noise

CNN works particulary well for perception models

Required

10. The advantages of camera lie in: *

Range of visibility

Object classification

Lane tracking

Object detection
