Hi,
I need a grayscale image to input into a function I want to create mesh on, problem is the image i have at the moment is a niftii (used in mri machines), how do i convert it into a grayscale? It (niftii) image is a matrix essentially with values [0 1] range, i believe you need [0 255] for grayscale. Any help to convert this to grayscale?
Thank You

According to my understanding.
You have binary image and you want to convert it to gray scale.
It may deal us to resampling of 2 bit image to 8 bit image?

If the range is [0,1] it is most likely continuous, not binary. See if:
grayImage = uint8(niftii_image*255);
does what you want.

‘... values are between 0 to 1 in that matrix, so it can be 0.5 0.6 etc. Anything in between.’
My code should do what you want.
