struct

For lmrcSinogramFETSetting

typedef struct lmrcSinogramFETInfo {
	int flagOutC;
	mrcImage* OutC;
	int flagsm;
	int sm;
	int outmode; // 1: ordinary 8 features 0: new 3 features
	int mode;
}lmrcSinogramFETInfo;

For lmrcSinogramFETPCASetting

typedef struct lmrcSinogramFETPCAInfo{
	FILE* inList;
	int flagInImage;
	mrcImage* inImage;
	Array X;
	Array Ave;
	Array C;
	Array u;
	Array lambda;
	Array fetpcad;
	FILE* Out;
	int mode;
}lmrcSinogramFETPCAInfo;

API

Calculation of Sinogram Features

Calculate Sinogram feature value.

extern void lmrcSinogramFET(mrcImage* in, mrcImage* out, lmrcSinogramFETInfo info, int mode);

Cut out line

Cut out data in Sinogram for calculation of Features.
Cut out only data that is above value depending on mean for each θ.

extern void lmrcSinogramFETcutout(mrcImage* in, mrcImage* out, int mode);

Smoothing

Perform smoothing to calculated Features.

extern void sinogramFETsmoothing(mrcImage* in, mrcImage* out, int sm, int mode);

Normalize

Normalize each Feature at using mean.

extern void lmrcSinogramFETc(mrcImage* out, mrcImage* OutC, int mode);

Normalize each Feature as minimum value is 0.

extern void lmrcSinogramFETminimam_Zero(mrcImage* in, mrcImage* out, int mode);
