• Data kinds: image2d × image2d → metrics

• Call: import imgmetrics; imgmetrics.compare_images(a, b, data_range=None, bins=64, channel_axis=None, ms=False) (or opsimgmetrics.get("compare_images"))

Usage

Measure several metrics at once and return what was measured and how, alongside the numbers.

防ぐため(この repo で実際に起きた事故の型)。

Returns

-------

dict

``{"mse", "rmse", "psnr", "ssim", "mutual_information",

"normalized_mutual_information", "ncd", "contract": {...}}``。

`ms=True なら ms_ssim も(成立しない大きさなら ValueError`)。

カラー画像で `channel_axis を渡すと delta_e_2000_mean` も入る。
