去模糊

通过反卷积实现去模糊

图像可能会因模糊而失真,例如运动模糊或失焦镜头造成的模糊。模糊由畸变算子表示,也称为点扩散函数 (PSF)。不同的去模糊算法根据您对图像中 PSF 和噪声的了解程度来估计和去除模糊。

Image Deblurring

Deblurring is a process that removes distortion from a blurry image, using knowledge of how the optical system blurs a single point of light.

Adapt the Lucy-Richardson Deconvolution for Various Image Distortions

The Lucy-Richardson deconvolution function enables you to deblur images with complicated distortions such as nonuniform image quality or undersampling.

Adapt Blind Deconvolution for Various Image Distortions

Although blind deconvolution algorithm does not require information about the blurring or noise, it enables you to deblur images that have complicated distortions such as nonuniform image quality or undersampling.

Create Your Own Deblurring Functions

To create your own deblurring functions, convert the distortion operator between the spatial and the frequency domains.

Avoid Ringing in Deblurred Images

Ringing is an artifact that appears as alternating bright and dark bands near edges. Reduce ringing by blurring the edges of the original image.
