Digital Video Anti-aliasing Filter
General Description
Anti-aliasing filter for use in digital video applications. Implements a 3x3 low-pass filter on the image pixels to remove high frequency artefacts such as jagged edges, stepped lines and moiré interference patterns. Ideal for use with image sensors and before video downscaling to vastly improve image quality.
Key Design Features
- RGB or YCbCr video in/out
- Fully pipelined architecture
- AXI4-stream compatible
- Choice of low-pass filter responses
- Small implementation size
Applications
- Low-pass (anti-alias) filtering before video scaling
- Optimization of video from image sensors and cameras
- Reduction of jagged edges, stepped lines and moiré patterns
