  • BM3D Introduction

    BM3D is the upgraded version of the NLM algorithm and has proven to be the best in
    image denoising in terms of higher PSNR. Because of its high computational
    complexity, it's usually used offline. BM3D mainly uses non-local patch matching.

    First, it searches for similar patches. While NLM will take weighted average of these similar patches, BM3D transforms these similar patches into a frequency domain, and uses collaborative filtering to reduce noise.

    Next it performs an inverse transformation to process those patches.

    Point Spread provides deeply-optimized hardware IP Cores of BM3D for RAW images.

    DSLR-level Hardware Noise Reduction IP Core Introduction

    Point Spread launched the BM3D IP core for real time 4K RAW images.

    It has improved noise reduction by over 30%, and generates less noise in dark scenes.
