Demo_deblur_real_application

[yxxxxxxxx]

这个demo跑不通，您知道为什么吗？ Error using edgetaper Expected input number 2, PSF, to be nonzero.

Error in edgetaper>parse_inputs (line 128) validateattributes(PSF,{'uint8','uint16','int16','double','single'},...

Error in edgetaper (line 34) [I, PSF, sizeI, classI, sizePSF, numNSdim] = parse_inputs(varargin{:});

Error in Demo_deblur_real_application (line 76) y = edgetaper(y, k);

Make sure you also provide the blur kernel because IRCNN takes the blurred image and blur kernel as input. For your own blurred image, please estimate the blur kernel by a blind deblurring method first, then you can use this code for non-blind deblurring.

我是直接跑的demo,然后出现了上述错误，那这个blur kernel是一张图片吗？比如说：kerneltestsets/Deblur_set2/im01_ker01_out_kernel.png

[cszn]

Yes, the blur kernel is saved as an image.

i am also encounter this question，how to solve it？thanks！

[Zonobia-A]

Can you tell me how to estimate the blur kernel by a blind deblurring method?

[cszn]

Some blind deblurring codes: https://github.com/rgbitx/image_deblur_code

Thanks！

The problem has been solved. See the details: https://github.com/cszn/IRCNN/blob/f47a52ae9849265843553639ee8767316f754e61/Demo_deblur_real_application.m#L74

I ever got similar errors in other codes.

Error using edgetaper Expected input number 2, PSF, to be nonzero.

Error in edgetaper>parse_inputs (line 128) validateattributes(PSF,{'uint8','uint16','int16','double','single'},...

Error in edgetaper (line 34) [I, PSF, sizeI, classI, sizePSF, numNSdim] = parse_inputs(varargin{:});

Actually, the error means that PSF is required not to contain zero elements by the function validateattributes(PSF,{'uint8','uint16','int16','double','single'},...

So, we need to check PSF to make sure it does not contain zeros. Alternatively, we can add PSF with very small numbers to eliminate zeros. It works in this way.
