This paper describes an objective comparison of the image quality of different encoders. [] Key Method We show that the MOS predictions by our proposed tool are a better indicator of perceived image quality than PSNR, especially for highly compressed images. For the encoder comparison, we compress a set of 29 test images with two JPEG encoders (Adobe Photoshop and IrfanView) and three JPEG2000 encoders (JasPer, Kakadu, and IrfanView) at various compression ratios.

JPEG2000 Still Image Coding Quality
TLDR
The image quality of the JJ2000 and Apollo algorithms is statistically equivalent for medical image compression, demonstrating the image qualities between two popular JPEG2000 programs.
An Analysis of Contemporary JPEG2000 Codecs for Image Format Migration
TLDR
It is found that in some circumstances, particularly when a JasPer encoder is used, in order to retain image quality of the decoded image, the best choice of decoder may not be the same codec used to create the JPEG2000; based on these results, the encoding library is therefore recommended technical preservation metadata to retain.

TLDR
A NND-based subjective experiment is carried out to see if the existing standard image codecs such as JPEG and JPEG2000 still make a reasonable difference in performance and results reveal that there is no great difference between the two standard codecs.
Performance comparison of JPEG, JPEG2000 & JPEG XR image compression standards
TLDR
The results show that recently developed JPEG standard (JPEG XR) is able to compress images with the same quality as JPEG2000, but not the same speed as JPEG.
Quantification of image quality after photobleaching and image compression
TLDR
Signal to noise ratio was used in this study to construct three lossy compression techniques, which preserve information contained in the images, and the compression efficiency was measured as a function of image brightness.
Study of subjective and objective quality assessment of infrared compressed images
TLDR
A new database with the aim of studying both subjective and objective image quality assessment (IQA) on compressed long wavelength infrared (LWIR) images and results show that objective IQA measures correlate with human subjective results with a degree of agreement up to 95%.
Quality of Compressed Medical Images
TLDR
It is found that the image contrast and the average gray level play important roles in image compression and quality evaluation and in the future, the image gray level and contrast effect should be considered in developing new objective metrics.
An Objective Comparison of Image Compression Techniques for JPEG Encoder
TLDR
The JPEG Encoder for image compression is dealt with upon comparing the performance of DWT compression with DCT compression, finding that DWT yields higher compression ratio and better visual quality.
Analysis of Relationship between Image Compression and Gamut Variation: JPEG and JPEG2000
TLDR
The rela- tionship between the compression ratio and the gamut variation for a reconstructed image using JPEG and JPEG2000 is investigated and gamut fidelity is obtained using the ratio of unique colors relative to thegamut area.
A survey on lossy compression of DSC raw data
TLDR
The study investigates the lossy compression of DSC raw data based upon the 12 bit baseline JPEG compression, finding that JPEG artefacts originate from the quantization of the DCT coefficients and is capable of compression ratios of about factor 4 in practice.

It is shown that quality assessment algorithms deal only with images and videos that are meant for human consumption, and that they outperform current state-of-the-art methods in my simulations.
