How do I remove the blur from an image in Matlab?
Deblurring is a process that removes distortion from a blurry image, using knowledge of how the optical system blurs a single point of light. The Lucy-Richardson deconvolution function enables you to deblur images with complicated distortions such as nonuniform image quality or undersampling.
How can I blur an image in Matlab?
output = blur(img,w); where img, the input image is a two-dimensional matrix of grayscale pixel values between 0 and 255. Blurring is to be carried out by averaging the pixel values in the vicinity of every pixel.
What is image deblurring in image processing?
An image deblurring is a recovering process that recovers a sharp latent image from a blurred image, which is caused by camera shake or object motion. It has widely attracted attention in image processing and computer vision fields. A number of algorithms have been proposed to address the image deblurring problem.
What is blind image deconvolution?
Blind image deconvolution is the process of estimating both the original image and the blur kernel from the degraded image with only partial or no information about degradation and the imaging system. It is a bilinear ill-posed inverse problem corresponding to the direct problem of convolution.
