Dataset training about image_segmentation

[LeeJunHyun]

Hello, @loaysh2010 .
You should use same size of ground truth.
Please check SR_Flat and GT_Flat size.

@LeeJunHyun ,
Thank you very much for your concern. Actually, I did check SR_Flat and GT_Flat size. the input image and GT image are the same size [1,3,256,256], but the SR image is [1,1,256,256], so I convert the GT image to grayscale [1,1,256,256] after flatting it be the same this. I hope that will overcome the problem.
Do you have any other idea?

@loaysh2010 ,
I think your GT has 3 classes.
If I am correct, then you should change the number of output channel of network.

@LeeJunHyun
my GT was saved as png colored image. so it has the shape of [1,3,256,256] where 3 is for RGB colors. So after converting it to grayscale it's shaped become [1,1,256,256] so when flatting it get the same size as SR flatted image.
do you think to change the number of output channel of the network better than convert the GT to grayscale with the previously mentioned shape ??

If your GT has RGB channel, each channel must have its own meaning, right?
If so, it would be batter that you just keep GT as colored image.

@LeeJunHyun Changed the output channel for the model to 3. and error fixed
Thanks for your time. You can close the issue

hello author,

how can i use your code for mutliclass segmentation. i have rgb ground truth.
thank you
