How do I decode a JPEG image?

JPEG decoding

1. Extract the Huffman tables and decode the bits.
2. Extract DCT coefficients by undoing the run-length and delta encodings.
3. Use DCT coefficients to combine cosine waves and regenerate pixel values for each 8×8 block.
4. Convert YCbCr to RGB for each pixel.
5. Display the resulting RGB image.
