http://www.emgu.com
Fills the destination array with values from the look-up table. Indices of the entries are taken from the source array. That is, the function processes each element of src as following: dst(I)=lut[src(I)+DELTA] where DELTA=0 if src has depth CV_8U, and DELTA=128 if src has depth CV_8S

Parameters

src
Type: Emgu.CVIInputArray
Source array of 8-bit elements
lut
Type: Emgu.CVIInputArray
Look-up table of 256 elements; should have the same depth as the destination array.
