It is a software-based image signal processing(SoftISP) application optimized by GPU. SoftISP --Options "Enable" Enable high quality noise reduction node
SoftISP Roles:
- Bad Pixel Correction
- White Balance
- Histogram Equalization
- High-quality Demosaicing
- High-quality Noise Reduction
Input Image:
- Bayer format raw data with color filter array of BG/GR
- Resolution: 1920x1080
Output Image:
- "0-SourceImage.bmp": Input image -> Demosaicing
- "1-RemoveBadPixel.bmp": Input image -> Bad Pixel Correction -> Demosaicing
- "2-WhiteBalance.bmp": Input image -> Bad Pixel Correction -> White Balance -> Demosaicing
- "3-Equalization.bmp": Input image -> Bad Pixel Correction -> Histogram Equalization -> Demosaicing
- "4-RemoveNoise.bmp": Input image -> Bad Pixel Correction -> Histogram Equalization -> Demosaicing -> Noise Reduction
