Introduction

Compression Artifacts

Digital video compression has introduced a new set of picture artifacts known in the industry as «mosquito noise» and «blocking artifacts». These new degradations coexist with analog video noise and become quite objectionable when seen on today’s large screen displays (see images below).

Algolith’s Flea has been engineered to reduce the appearance of noise and compression artifacts, allowing for a much better viewing experience.

Flea

Flea is a three-dimensional digital noise reduction processor, designed to clean up signals from DVD Players/Recorders, Satellite Receivers, Cable Decoders, PVRs and other digital devices using MPEG-2 compression.

Flea performs four distinct image noise reduction techniques.

1- Mosquito noise is removed, using Algolith’s proprietary region-based algorithm.

2- Block Artifact Reduction (BAR) blends and diminishes the inherent 8 x 8 pixel block structures of MPEG2 images.

3- Algolith’s advanced motion adaptive temporal filtering eliminates “bad reception and low light” noise.

4- Flea provides image enhancement using non-linear filters for exceptionally sharp and noise free pictures.
