/* Inside dimension is measure of nearby complexity, that reflects the energy
|
|
of nearby coefficients are nonzero. For the first coefficient (DC, unless
|
|
block type is 0), we look at the (already encoded) blocks above and to the
|
|
left of the current block. The context index is then the number (0,1,or 2)
|
|
of these blocks having nonzero coefficients.
|
|
After decoding a coefficient, the measure is determined by the size of the
|
|
most recently decoded coefficient.
|
|
Note that the intuitive meaning of this measure changes as coefficients
|
|
are decoded, e.g., prior to the first token, a zero means that my neighbors
|
|
are empty while, after the first token, because of the use of end-of-block,
|
|
a zero means we just decoded a zero and hence guarantees that a non-zero
|
|
coefficient will appear later in this block. However, this shift
|
|
in meaning is perfectly OK because our context depends also on the
|
|
coefficient band (and since zigzag positions 0, 1, and 2 are in
|
|
distinct bands). */
