This tool computes (dis)similarity between two or more PNG images
|
|
using an algorithm approximating human vision.
|
|
|
|
Comparison is done in L*a*b* color space (D65 white point, sRGB gamma)
|
|
using a multi-scale variant of the SSIM algorithm.
|
|
|
|
Features:
|
|
- Improved algorithm
|
|
- Compares at multiple weighed resolutions, and scaling is done in
|
|
linear-light RGB. It's sensitive to distortions of various sizes
|
|
and blends colors correctly to detect e.g. chroma subsampling errors.
|
|
- Uses L*a*b* color space for the SSIM algorithm. It measures
|
|
brightness and color much better than metrics from average of
|
|
RGB channels.
|
|
- Supports alpha channel.
|
|
- Supports images with color profiles.
|
|
- Takes advantage of multi-core CPUs.
|
|
- Can be used as a library in C, Rust, and WASM.
|
|
- No OpenCV or MATLAB needed.
