(eng): Sensor and lens blur degrade images acquired by digital cameras. Simple and fast removal of blur using linear filtering, such as Wiener filter, produces results that are not acceptable in most of the cases due to ringing artifacts close to image borders and around edges in the image. We have developed deconvolution algorithm with ringing artifact suppression implemented with simple filtering and element-wise softthresholding.
