[lu-zero]

It would look much better as table.

This looks like already completed:

av-metrics/av_metrics_tool/src/main.rs

Lines 337 to 358 in 4f02409

	OutputType::Markdown(w) => {
	writeln!(
	w,
	"|filename|psnr|apsnr|psnr_hvs|ssim|msssim|ciede2000|\n\
	|-|-|-|-|-|-|-|"
	)
	.map_err(|err| err.to_string())?;
	for cmp in self.comparisons.iter() {
	writeln!(
	w,
	"|{}|{}|{}|{}|{}|{}|{}|",
	cmp.filename,
	cmp.psnr.map(|v| v.avg).unwrap_or(-0.0),
	cmp.apsnr.map(|v| v.avg).unwrap_or(-0.0),
	cmp.psnr_hvs.map(|v| v.avg).unwrap_or(-0.0),
	cmp.ssim.map(|v| v.avg).unwrap_or(-0.0),
	cmp.msssim.map(|v| v.avg).unwrap_or(-0.0),
	cmp.ciede2000.unwrap_or(-0.0)
	)
	.map_err(|err| err.to_string())?;
	}
	}

Safe to close the issue, or?
