Hi,

I am only trying to recreate this example: https://www.mathworks.com/help/images/unsupervised-medical-image-denoising-using-unit.html

I get this error :

the image or images you're forwarding through dl network is colored ( has 3 channels - RGB most probably). try rgb2gray function on your dataset for set channel dimension to 1.

thanks for your response, i convert my dataset by rgb2gray function, and I get this error :

[Abolfazl Chaman Motlagh]

there are 6 supporting functions at the end of the page. including 'modelGradientGen' (https://www.mathworks.com/help/images/unsupervised-medical-image-denoising-using-unit.html)

copy all of them at the end of your script and run it again.

(or for each one create a .m file with it's name to use it as function.)

these functions are used inside the scripts but apparently you didn't include them, that's why you get this error.

[Abu Yusuf]

I already included them

[Abolfazl Chaman Motlagh]

if you can ,attach your script. maybe i could help.

i

[Abolfazl Chaman Motlagh]

you miss modelGradientGen function in supporting functions. Try attached code.

[Abu Yusuf]

i still get the same error

[Abolfazl Chaman Motlagh]

that shouldn't be possible :) (because the error is "there is no modelGradientGen value or function but we just add it!)

ok. fix your own code by adding modelGradientGen to supporting functions yourself. and run it.
