lmrcImageCommonLine(API)

DataManip/mrcImage/src/lmrcImageCommonLine is API for Common Line Search. It is ued by mrcImageCommonLineSearch, etc..

struct

Common Line Mode

It is used as mode for lmrcImageCommonLineInfoOutput.

typedef enum lmrcImageCommonLineMode {
	lmrcImageCommonLineModeImageCenterIsGC = 1
} lmrcImageCommonLineMode;

Search Mode

Setting data as value of searchMode (lmrcImageCommonLineSearch 's member)

typedef enum lmrcImageCommonLineSearchMode {
	lmrcImageCommonLineSearchModeFourierSpace = 0,
	lmrcImageCommonLineSearchModeRealSpace = 1 
} lmrcImageCommonLineSearchMode;

Common Line Information

Setting data for lmrcImageCommonLineSearch.

typedef struct lmrcImageCommonLineInfo {
	/* Input */
	double dtheta;
	lmrcImageCommonLineSearchMode searchMode; 
	/* Output */
	double optimumThetaIn;
	double optimumThetaRef;
	double optimumCor; 
} lmrcImageCommonLineInfo;

API

Common Line Search

Output angle of Common Line from 2 image files.

extern void lmrcImageCommonLineSearch(mrcImage* out, mrcImage* in, mrcImage* ref, lmrcImageCommonLineInfo* linfo, int mode);

Input data

mode: In the case of setting lmrcImageCommonLineModeImageCenterIsGC, Move so that origin is center of gravity before correlation.

Select correlation method by linfo->searchMode.

searchMode	Value	Correlation Method
lmrcImageCommonLineSearchModeFourierSpace	0	Fourier Shell Correlation
lmrcImageCommonLineSearchModeRealSpace	1	Sinogram Correlation

Output data

Output Correlation Map to out.
In the case of Fourier Shell Correlation(searchMode=0), it stores data at when correlation value is max to linfo 's member.

linfo 's member	Output
optimumThetaIn	in 's Projection Angle
optimumThetaRef	ref 's Projection Angle
optimumCor	Correlation value

Output setting data

extern void lmrcImageCommonLineInfoOutput(FILE* fpt, lmrcImageCommonLineInfo* linfo, int mode);

Output Help message

extern void lmrcImageCommonLineInfoUsage(FILE* fpt);
