Digital Image Processing MCQ Questions And Answers

Explanation: The Brightness levels are distributed over the spatial area. Hence, the spatial coordinates are proportional to brightness levels.

Explanation: Digital image processing is more flexible and agile techniques as it is fast, accurate and reliable

Explanation: The image is a collection of dots with a definite intensity or amplitude.

Explanation: True, An Image is a collection of individual points referred as pixel, thus a Pixel is the element of a digital image.

Explanation: Steps in image processing:
Image acquisition-> Image enhancement-> Image restoration-> Color image processing-> Wavelets and multi resolution processing-> Compression-> Morphological processing-> Segmentation-> Representation & description-> Object recognition.

Explanation: Morphological processing deals with tools for extracting image components that are useful in the representation and description of shape. The material in this chapter begins a transition from processes that output images to processes that output image attributes.

Explanation: Image compression is familiar (perhaps inadvertently) to most users of computers in the form of image file extensions, such as the jpg file extension used in the JPEG (Joint Photographic Experts Group) image compression standard.

Explanation: True, A normal T.V have 512 x 512 resolution.

Explanation: The gray values are interpreted as the power of number of colors. In monochromatic image the number of colors are 2.

Explanation: Segmentation procedures partition an image into its constituent parts or objects. In general, autonomous segmentation is one of the most difficult tasks in digital image processing. A rugged segmentation procedure brings the process a long way toward successful solution of imaging problems that require objects to be identified individually.
