hiftool's Issues

Calculation of “SRF matrix”

Dear author, I would like to ask you about the weight parameter "SRF" in spectral degradation. I read the SRF matrix under the R key you provided in 'Dataloader_tool/srflib/chikusei_128_4.mat' and you also provided the Sentinel2A_191_13.mat file. In practice, how should we calculate the "SRF matrix" required to degrade to certain bands under the Sentinel2 sensor? I really hope to get your advice! Looking forward to your reply!

关于Fusformer的训练测试

作者你好:
使用chikusei训练Fusformer
在训练时,CUDA out of memory,我将batch size从2改成1,可以进行训练。但是测试的时候out of memory。我想使用

output_HRHSI = torch.empty_like(GT)
            t = 4
            sf = 4
            n_ = GT.shape[2]
            for i in range(t):
               for j in range(t):
                   n = n_//t
                   output_HRHSI[:,:,i*n:(i+1)*n,j*n:(j+1)*n] = model(LRHSI[:,:,i*n//sf:(i+1)*n//sf,j*n//sf:(j+1)*n//sf],
                                                                     HRMSI[:,:,i*n:(i+1)*n,j*n:(j+1)*n])

是否是在训练的时候使用的是512x512的图片,所以网络是512的;而测试的时候拆分后图片是128x128,二者不对应。是否应该在训练的时候同样拆分图片,还是改什么超参数就行?

关于雄安数据集的频谱数量

作者你好:
在看论文和模型代码过程中,发现雄安数据集hsi_channel数量有差异,你在论文中描述雄安数据集hsi_channel的数量是250,但是在GitHub上代码,hsi_channel是93,你可以跟我解释一下为什么要这样子吗?

关于Network_eval.py

你好,昨天我用chikusei数据集训练了PSRT,PSNR是正常的,50多。但是使用Network_eval.py测试的时候,无论用的是from utils import PSNR_GPU还是imgvision,计算出的PSNR都是5左右,请问是怎么回事
