Denoising X-ray image is an important preprocessing process to measure BMD (Bone Mineral Density) correctly. In this paper, we deal with denoising X-ray image in DEXA (Dual-Energy X-ray Absorptiometry) system. Image noise in DEXA is modeled by separating source and detector noises. Using the noise model in DEXA, a noise reduction method is proposed. The proposed denoising method consists of Wiener...
