Degradation can be estimated by

• 2 ways

• 3 ways

• 4 ways

• 5 ways

Power spectra and noise of undegraded image must be known as.

• Wiener filter

• Notch filter

• Band pass filter

• None of these

Degraded image is produced using degradation process and

• Pixels

• Destruction

• Coordinates

• Additive noise

Degraded image is obtain in a

• Frequency domain

• Spatial domain

• Time domain

• Plane

What is the Principle sources of noise arise during image ?

• Restoration

• Acquisition

• Destruction

• Degradation

From where, Periodic noise arise

• Electric interference

• Gamma interference

• Beta interference

• None of the above

Which is not a type of noise ?

• Gamma noise

• Rayleigh noise

• Black noise

• Exponential noise

Band reject filters are used where the noise components are usually

• Known

• Unknown

• Taken

• Reject

SNR in noise stands for

• Signal to noise ratio

• Serial to noise ratio

• Signal to notch ratio

• Serial to notch ratio

The approach to restoration is

• Spike filtering

• Black filtering

• Ranking

• Inverse filtering
