Hi,
I have made changes to an image but it comes across as not what i want.
To solve this i took the original image and said x = imshow(image, [0 255]);
how can i turn 'x' into a matrix of values, such that when i type y=imshow(x) it returns the modified image.

x = uint8(x);
If the class of x is double, matlab assumes the intensity range is 0-1. When the class is uint8, matlab assumes the range is 0-255 since that the range of 8-bit unsigned integers.

Sounds like you're calling the function image instead of converting whichever variable contains your image. Either your image variable is not in scope, or it's not called image.
This is why we recommend not to use image as a variable name (or sum, mean, min, etc.) since it's too easy to run into these sort of bugs.

@Optical_Stress How did you fix it?
