Spatio-temporal noise removal method using block classification and display device using the same |
摘要 |
A spatio-temporal noise removal method using block classification that removes noise from a third field by using first, second, and third fields which are continuously inputted. The method includes generating first, second, and third motion-compensated fields; classifying blocks of the third field into a uniform region and a non-uniform region based on a variance value of a generated difference image; performing temporal filtering over every block of the third field; performing spatio-temporal filtering over every block of the first and third motion-compensated fields and the third field and performing the temporal filtering over the every block of the third field based on spatially-filtered value; and outputting a third noise-removed field by applying a weighted value to the temporal-filtered value and the spatio-temporal-filtered value.
