A Survey of Loss Functions for Semantic Segmentation

EasyChair Preprint no. 4058

6 pagesDate: August 19, 2020


Image Segmentation has been an active field of research, as it has the potential to fix loopholes in healthcare, and help the mass. In the past 5 years, various papers came up with different objective loss functions used in different cases such as biased data, sparse segmentation, etc. In this paper, we have summarized most of the well-known loss functions widely used in Image segmentation and listed out the cases where their usage can help in fast and better convergence of a Model. Furthermore, We have also introduced a new log-cosh dice loss function and compared its performance on NBFS skull stripping with widely used loss functions. We showcased that certain loss functions perform well across all datasets and can be taken as a good choice in unknown-distribution datasets. The code is available at
