摘要
被污点污染的数字照片的复原是新的研究课题;利用静态数字摄像设备可以在相同污染条件下反复拍摄的特点,提出一种根据参考照片来自动检测污点并且修复照片的方法。该方法首先对单色照片的污点进行定位并提取颜色特征,然后利用这些信息对其它含有同样污点的照片进行补偿。实验表明,该方法能够在不损失原始图像信息的情况下有效地去除数字照片中的污点,复原效果良好。
The restoration of digital picture stained by dust spots is becoming a new research subject.In respect that digital still camera is capable of constantly taking pictures under the same dust-stained situation,we put forward a method which can automatically detect the dust spots and restore the image.In this method,the position and color characteristics of dust spots are analyzed in a reference monochrome image,and then use those information to restore other images which are stained by the same dust pattern.It have been proved by experiments that this method can effeciently elimanate the dust spots without losing any original information of the images.
