-<dd><p>Compare current image to a reference using the provided threshold. If the comparison fails, ie. error is higher than the threshold, this outputs the resulting diff and error and return false, return true otherwise. The error is minimum between Minkownski and Wasserstein distance on a SSIM computation, as specified in VTK. Please note, due to possible arithmetic imprecision in the SSIM computation using a threshold of zero may return false with identical images. Depending on the VTK version, another comparison algorithm may be used. Threshold should be in range [0, 1[, this returns false otherwise. 1e-14: Pixel perfect comparison. 0.04: Visually indistinguishable. 0.1: Small visible difference. 0.5: Comparable images. 1.0: Different type, size or number of components </p>
