Parameters

gxNetShared
Type: GeoEngine.Core.GXNetXCGXNETCore
A shared CGXNETCore
imgi
Type: GeoEngine.Core.GXNetXCIMG
Handle to input image
imgo
Type: GeoEngine.Core.GXNetXCIMG
Handle to output image
tr_option
Type: SystemInt32
0-calculate, 1-given, 2-replace
edge
Type: SystemInt32
<define>IMU_TREND</define>
order
Type: SystemInt32
Trend order
vm
Type: GeoEngine.Core.GXNetXCVM
VM holds coefficients
num_coefs
Type: SystemInt32
Number of coefficients
Remarks
Both Images must be of type <define>GS_DOUBLE</define>. The VM parameter must be of type REAL, and be of size 10 at most. The number of coefficients must be compatible with the order of the trend removed. Following is the number of coefficients which should be present for a given order ===== ====================== Order Number of Coefficients ----- ---------------------- 0 1 1 3 2 6 3 10 ===== ======================
