Quantization and Sampling Test

In this quiz we will ask about two key stages in digital image processing. Sampling and quantization.

 

A binary image always has lower spatial resolution than an 8-bit gray scale image.

An 8-bit image is represented by a 4-bit per pixel display. Which operation will be applied to the input image in order to be able to be displayed? 

Down-sampling of an image will not cause contour artifacts in an image.  

An 8-bit image has always higher size than a 2-bit image.

Which type of resolution depends on Nyquist sampling theory?
