| 摘 要： | 运动模糊图像恢复讨论的是对运动物体所拍摄的模糊图像进行精确恢复,恢复的关键在于精确获取点扩展函数的参数。本文提出了一种点扩展函数自动获取方法,该方法通过计算机分析运动模糊图像频谱图,能够自动获取点扩展函数的运动方向和模糊长度,避免了人机交互的繁琐和不准确。通过实验仿真并与其他点扩展函数的参数获取方法做比较,验证了该方法的准确性和实用性。

| Abstract: | Motion blurring image restoration discusses the precise restoration of images which are taken while the object is moving.The key of restoration is to obtain the point spread function parameters precisely.This paper proposes a method to obtain the point spread function automatically.By analyzing the frequency chart of motion blurring images,we can automatically obtain blurring direction and length of the point spread function.It avoids the troubles and incorrectness of human-computer interaction.The practicability and veracity of arithmetic has been proved by simulating and by comparing with other PSF parameters acquiring methods. |
