图像和视觉相关的loss函数
- L1 / L2 loss
最常用loss函数,属于 pixel loss,即直接拟合目标图像。只能针对对齐的pair数据。
- Charbonnier loss
ref: Fast and Accurate Image Super-Resolution with Deep Laplacian Pyramid Networks section 3.3
-
TV loss(total variation)
-
content loss(vgg loss)
约束内容一致性,可以通过pretrained VGG等网络提取特征。
- texture loss
约束纹理风格一致性
- GAN loss
生成结果符合目标图像分布
-
Cross-Entropy loss
-
IOU loss
-
Dice loss
-
Focal loss
-
Lovasz loss
-
Tversky loss
-
AE loss(Associative Embedding Loss)
-
Balanced L1 loss
