A temporal mosquito noise corrector

摘要

Due to the required memory space and computing time, temporal processing is rarely used even in video processing. However, when the temporal aspect of a compression noise is major, it cannot be treated spatially only. The following article presents an example of such a noise: the mosquito noise. The equally spatial and temporal nature of the mosquito artifact is first explained through its definition. It is followed by the different ways already used to treat it. A spatio-temporal and compression-independent mosquito noise corrector is then introduced. Finally, the interest of a temporal corrector over purely spatial ones is shown through tests results.
