Binalization

Main

extern void    lmrcImageBinarization(mrcImage* out, mrcImage* in, lmrcImageBinarizationInfo linfo, int mode);

If higher bit in 1 byte(&0xf0) is 1 or more, perform special process before usual binalization process.

mode	used function
0x00	no process
0x10	lmrcImageDeterminationOfThresholdForBinarizationByKittlerMethod
0x20	lmrcImageDeterminationOfThresholdForBinarizationByOhtsuMethod
0x30	lmrcImageDeterminationOfThresholdForBinarizationByptileMethod
0x40	lmrcImageDeterminationOfThresholdForBinarizationByDifferentialHistogramMethod
0x50	lmrcImageDeterminationOfThresholdForBinarizationByLaplacianHistogramMethod

Usual process

extern void    lmrcImageBinarization0(mrcImage* out, mrcImage* in, lmrcImageBinarizationInfo linfo, int mode);

Special process

Kittler Method

extern double  lmrcImageDeterminationOfThresholdForBinarizationByKittlerMethod(mrcImage* mrc, int L, int mode);

Ohtsu Method

extern double  lmrcImageDeterminationOfThresholdForBinarizationByOhtsuMethod(mrcImage* mrc, int L, int mode);

p-tile Method

extern double  lmrcImageDeterminationOfThresholdForBinarizationByptileMethod(mrcImage* mrc, int L, double p, int mode);

Differential-Histogram Method

extern double  lmrcImageDeterminationOfThresholdForBinarizationByDifferentialHistogramMethod(mrcImage* mrc, int L, int mode);

Laplacian-Histogram Method

extern double  lmrcImageDeterminationOfThresholdForBinarizationByLaplacianHistogramMethod(mrcImage* mrc, int L, int mode);

Calculating threshold by Ohtsu Method

extern double  determinationThresholdFromGraylevelHistogramByOhtsuMethod(int* tile, int L);
