Explain in detail how JPEG compression works, and how JPEG2000 compression works in comparison. What are the advantages of these two types of compression

Answers:

below are my findings.. these are the comparison i got from two sources.

          Aspect                          JPEG                   JPEG2000
      How it Works?
  • Utilizes only lossy compression.
  • Limited to only RGB data.
  • It makes images look inexpensive, due to the low complexity of technique, when using systems such as camera and viewers.
  • Offers both lossy and lossless compression in the same file stream
      Advantages?
  • Offers the flexibility to either select high picture quality with fairly high compression ratio.
  • Can get a high compression ratio
  • Better compression tools than JPEG to have a high quality outcomes.
  • Produce higher quality of final image even though when using lossy compression.
  • Can handle higher channels of information compared to JPEG.
  • The outcomes of JPEG2000 looks more clear than the JPEG data compression.
  • Able to display images at different  resolution and sizes from same image files.
