你好，我想请问一下，CCM矩阵中出现负值是合理的吗，在进行apply_color这一步的时候输入的图像，为什么rgb通道会出现负值，而且大量负值出现在green和blue通道上，导致torch.clamp(image, 1e-8, 1.0)这一步使得负值变为1e-8，最后IAT输出图像的时候变为0，生成的图像为红色图像，请问能为我解答一下这个问题吗 @cuiziteng

你是自己训练的这个模型出问题了吗，还是用的预训练权重出问题？

是自己训练的模型

IAT_high部分的实验存在问题，我后面会重新check一下，另外您最后得到的mAP指标是否正常呢

这个偏红色的原因好像不是出在apply_color，我之前也遇到这个问题，后来我拿其他的这种端到端模型，比如DENet放到yolo前面，出来的也是偏红色的，放到mmdetection里面训练的
