What Hacker News says

There's tools like JpegMini, which tries to detect when artifacts become annoying.
There's an open source re-implementation of their published algorithm on github, but they have patents, which might be part of Flickr's reticence:
https://github.com/dwbuiten/smallfry
In Perceptual Image Compression at Flickrjpegmini works by compressing an image as much as possible while keeping the distortion calculated by there particular metric below a threshold. To compare against mozjpeg you'd need to compress a bunch of images with JPEGMini and then compress those images with mozjpeg so that they were the same size. You could then compare the quality of the resulting images.
The test set of images is here:
https://github.com/bdaehlie/web_image_formats/tree/master/im...
If you're interested, https://github.com/dwbuiten/smallfry is program similar to JPEGMini that uses mozjpeg as its backend.
