EColorLookup::GetIndexBits

EColorLookup::SetIndexBits

Number of bits used for indexing the lookup table.

Namespace: Euresys::Open_eVision

[C++]

OEV_UINT32 GetIndexBits()

void SetIndexBits(OEV_UINT32 un32IndexBits)

Remarks

Before filling in a lookup table, it is necessary to decide how many table entries it requires. The EColorLookup::IndexBits property indicates how many (high-order) bits of the input components are used. The relation between EColorLookup::IndexBits, the number of table entries and the corresponding table size are given below: The larger the number of entries, the more accuracy is obtained. After EColorLookup::IndexBits has been changed, the lookup table needs to be recomputed.

Note. Be aware that each time a color lookup table is filled, all the entries are recomputed. When EColorLookup::IndexBits equals 6, this may take a very long time. Such large lookup tables should be computed once only. Different combinations of EColorLookup::IndexBits and Interpolation provide a trade-off between accuracy and speed for the table pre-computation and table use.
