Question 8

+2 marksOne correct option

Given is a 3×33 \times 3 8-bit grayscale image:

[50701209030804060110]\begin{bmatrix} 50 & 70 & 120 \\ 90 & 30 & 80 \\ 40 & 60 & 110 \end{bmatrix}

What is the mean of transformed pixels of after applying linear contrast stretching? Linear contrast stretching is an image enhancement technique used to improve the contrast in an image. This is achieved by linearly scaling the pixel values so that they span a desired range (0 to 255 for an 8-bit grayscale image).
