In this paper we present the modified SSIM (SSIMmod) and simplified SSIM (SSIMsimpl) measures and compare them with 3 objective measures (MSE, original SSIM and VIF). Objective measures are compared using 7 publicly available subjective image quality databases and 3 correlation types (Pearson's, Spearman's and Kendall's correlation). Results show that SSIMmod gives higher correlation than original SSIM, while SSIMsimpl with similar weighted mean correlation as original SSIM achieves faster calculation time.
