摘　　要：提出了荧光造影图像序列的图像恢复方案。将新的强度约束合并到Miller正则化公式中,以获得保持高强度像素的能力。恢复的图像除了受光滑约束的影响之外,也会受到强度约束的影响。恢复过程中,采用从预滤波过程中获得的强度模板实现强度约束,该模板代表一幅由所期望强度值组成的图像。实验表明,该方案在高强度保持和图像恢复两方面都获得了较好的结果。A new approach of image restoration for the sequence of fluorescein angiography was proposed.First,the intensity constraint was incorporated into Miller regularization equation to obtain the ability to preserve the high intensity of pixels.Thus,the restored image would be influenced not only by the smoothness constraints,but also by the intensity constraints.Secondly,in the process of the restoration,we use an intensity template obtained from the pre-filtering procedure was used to achieve the intensity constraints.The template represented an image composed by the desired intensity value.The experiments show that the proposed scheme gains a better result in both high intensity preservation and image restoration.
