Does I-frame coding in HEVC offer lossless image compression? If so, what algorithm is used for this purpose? Kindly share details of some recent work/ articles.
I am working on lossless image compression scheme for colour images. As the I-frame is encoded individually and independent of other frames of a video, I assume the I-frame lossless compression algorithm can be applied to single image compression as well. Am I right?
Kindly share information about any good articles preferably recent ones that depict lossless compression of images using the techniques developed for I-frame.
Yes, HEVC intra coding is capable of intra coding. For the prediction you can apply all prediction tools that are available for I pictures. It get lossless by setting the QP to 0 (for 8 bit/sample signals) or lower for higher bit depth and by disabling the transform coding (i.e. by using transform skip).
