Explain the JPEG modes of operations?
Answer:
Following are the JPEG operation modes:
- Lossless Mode: Every pixel in the image is encoded even though the compression ratio is low.
- Sequential Mode: A single scan from left-to-right and top-to-bottom compresses the image.
- Progressive Mode: Multiple scans are used to compress the image. The transmission time is long.
- Hierarchical Mode: Multiple resolutions are used to compress the image. Hence the lower resolution is accessed first which does not require the decompressing the whole resolution of the image.
