How researchers see this paper

The researchers whose trusted networks rank it highest, strongest advocate first. Every researcher gets a different order.

End-to-end optimization of nonlinear transform codes for perceptual quality (2016, background): “, [13], [14]), but these were generally limited to optimizing weighting matrices for the DCT.”
DCT-domain watermarking techniques for still images: detector performance analysis and a new structure (2000, methodology): “[18], [19], which has been applied by Watson to the adaptive computation of quantization matrices in the JPEG algorithm [20].”
Just noticeable distortion model and its applications in video coding (2005, background): “, [1,31,33–35,14]), but there are relatively fewer reports for JND in image domain.”
Spatio-Temporal Just Noticeable Distortion Profile for Grey Scale Image/Video in DCT Domain (2009, methodology): “1) Human visual sensitivity has directionality [21], [33].”
A standard model for foveal detection of spatial contrast. (2005, background): “LP This function is a parabola in a graph of log-sensitivity versus log-frequency (Ahumada & Peterson, 1992; Rohaly & Owsley, 1993).”
