Question

The Logarithmic Contrast Stretching is mostly used for _____________.
(a.) Brighter parts of images
(b.) Darker parts of images
(c.) Higher difference in grey levels
(d.) Lower difference in grey levels

Answer 1

Answer:

higher difference in gray level.

Answer 2

Answer:

The correct answer is (B) darker parts of the image. The Logarithmic Contrast Stretching is mostly used for enhancing the details in the darker parts of an image, thus compromising the details present in the brighter regions of the same image.

Therefore, as a result of this process, the darker regions of the image become brighter whereas the brighter regions lose some details. However, there's not much significant change observed in the brighter areas.
