Hi,
I'm using ENVI 5.3 to run grey level co-occurrence texture analyses on a series of LiDAR-derived canopy height models. I have a question regarding the "Grey Level Quantization Levels" feature of the ENVI co-occurrence tool:
Do the grey level quantization levels represent a limit in the number of values being considered by the matrix? I ask because I'm working with a collection of 8-bit rasters with values ranging from 0-63. With an 8-bit pixel depth, my data represents just 63 of 256 possible values, and so my co-occurrence matrices are filled with a large number of 0's which I've read can mess up the calculation. Limiting the data to 64 possible values would be perfect, but I'm not sure that this is what the quantization feature does.
Any helps is HIGHLY appreciated!
Best,
Jamie Ervin
