API

Sinogram Transform

Transform from 2D image to Sinogram image

extern void lmrcImageSinogramCreate(mrcImage* out, mrcImage* in, lmrcImageSinogramInfo* linfo, int mode);

Sinogram Correlation

Main

extern void lmrcImageSinogramCorrelation(mrcImage* out, mrcImage* in, mrcImage* ref, lmrcImageSinogramInfo* linfo, int mode);

Select a correlation method by setting mode and linfo->LengthMode.

mode	Correlation method
0	simple Correlation(lmrcImageSinogramCorrelation0)
1	weight Correlation(lmrcImageSinogramCorrelation1)
2	threshold Correlation(lmrcImageSinogramCorrelation2)
3	power weight Correlation

Correlation of each mode

void lmrcImageSinogramCorrelation0(mrcImage* out, mrcImage* in, mrcImage* ref, lmrcImageSinogramInfo* linfo, int mode);
double lmrcImageOneLineSinogramCorrelation0(mrcImage* in, mrcImage* ref, int mode);

void lmrcImageSinogramCorrelation1(mrcImage* out, mrcImage* in, mrcImage* ref, lmrcImageSinogramInfo* linfo, int mode);
