What is the advantage of piece-wise enhancement technique?
(a.) Is applied when there is high contrast in grey levels
(b.) Different enhancement techniques can be applied for different parts of the image
(c.) Divides the image into pieces and applies an enhancement technique
(d.) Is applied for highly heterogeneous land use
Answers
Answer:
The correct option for the given question is option d.
Explanation:
The advantage of piece wise enhancement technique is it is applied for highly heterogeneous land use.
It enhances the image quality E and also enhances the linear transformations that takes place.
Hence it is the mostly used technique applied now a days.
Answer:
The advantage is (c) Divides the image into pieces and applies the enhancement technique.
Explanation:
The piece-wise enhancement technique is used when the histogram in the image is bi or remodel. The histogram of an image describes the value of pixel intensity. The use of piece-wise enhancement stretches numbers of the histogram to increase the level of enhancement in certain areas of the images.
Enhancing involves identification of necessary steps that linear enhancement increases brightness. The histogram shows number of pixels at different intensity values.
