“…The first methods in this class of NR QE were designed to predict the Mean-Squared-Error (MSE) caused by block-based compression like MPEG-2 [83][84][85][86][87], JPEG [87,88], or H.264 [89,90,87,91,92]. With the exception of [84], which uses the decoded pixels v test , these techniques use information only from the received bitstream.…”

“…With the exception of [84], which uses the decoded pixels v test , these techniques use information only from the received bitstream. The basic approach is to model the DCT coefficients using a Laplacian distribution, and estimate the Laplacian parameter for each of the 8 Â 8 coefficients.…”

“…Multi-scale SSIM (MS-SSIM), Gradient-based SSIM (GSSIM) and a Complex Wavelet transform domain version of SSIM (CW-SSIM) were proposed based on SSIM [4,27,28]. Also, there are other emerging issues about reduced reference [12], no-reference method [23] and hybrid perceptual bit stream method [11]. The reduced reference methods extract some features of both the original video and compressed video and compare the features to obtain a quality score.…”

“…When properly implemented, subjective methods yield accurate Objective models of image quality [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21], instead, estimate perceived quality while bypassing human assessors. These models predict image quality by processing numerical quantities (''objective features'') extracted from images.…”

“…In the specific case of picture-enhancement algorithms, one has to rely on a ''univariant'' approach, i.e., to assess the perceived quality from processed images only. Univariant approaches have recently been proposed for that purpose [10,11,[18][19][20][21], and are based on a non-linear function of image features. However, existing univariant approaches have been designed to assess the quality of compressed images rather than enhanced images.…”
