Abstract:Objective: This paper proposes a new objective function to improve the quality of synthesized breast CT images generated by the GAN and compares the GAN performances for transfer learning datasets from different image domains.
Approach: The proposed objective function, named beta loss function, is based on the fact that X-ray-based breast images follows the power-law spectrum. Accordingly, the exponent of the power-law spectrum (beta value) for breast CT images is approximately two. The beta loss funct… Show more
