Fast LCD motion deblurring by decimation and optimization
The LCD deblurring problem is considered as a simple bounded quadratic programming problem and is solved using conjugate gradient with early stopping criteria to avoid excessive search. A decimation and interlace interpolation method is introduced to reduce the computing time. Solutions are competitive to those the generated by conventional Lucy Richardson algorithm, but using much shorter amount of time. The method can be extended to higher decimation factors. Visual subjective tests are conducted to justify our proposed method.
