摘要 CDD模型是在全变分(TV)去噪模型基础上发展而来的一个图像修复模型。对变分修复模型做一个综述,详细阐述CDD修复模型的构造过程,用变分法推导出与之相应的偏微分方程(PDE),并用半点中心差分法对该模型进行数值仿真。摘要: CDD is a digital image inpainting model based on TV denoising model. Surveys the image inpainting model based on TV model, elaborates the construction of the CDD inpainting model, and deduces the PDE related to it. And uses the half point center difference method to simulate the model.
