| WlzObject * | WlzHistogramObj (WlzObject *srcObj, int nBins, double binOrigin, double binSize, WlzErrorNum *dstErrNum) |
| Creates a woolz histogram object (with an int histogram domain) using the given 2D or 3D woolz domain object and histogram parameters. If the requested number of bins is zero then the number of bins, the origin and the bin size will be computed as follows: More... | |
| WlzObject * | WlzHistogramCopy (WlzObject *srcHistObj, WlzObjectType dstType, WlzErrorNum *dstErrNum) |
| Copies the given Woolz histogram object to a new one of the required type. More... | |
| WlzObject * | WlzHistogramRebin (WlzObject *srcHistObj, WlzObjectType dstType, int dstMaxBins, int dstNBins, double dstOrigin, double dstBinSize, WlzErrorNum *dstErrNum) |
| Re-bins the given Woolz histogram object to a new one of the required type, number of bins, origin and bin size. More... | |
| WlzErrorNum | WlzHistogramRsvFilter (WlzObject *histObj, WlzRsvFilter *flt) |
| Applies an infinite impulse response (IIR) filter to the histogram object'c bin values. More... | |
| WlzErrorNum | WlzHistogramConvolve (WlzObject *histObj, int krnSz, double *krn) |
| Convolves the given Woolz histogram object's histogram bin values with the given convolution kernel. More... | |
| WlzErrorNum | WlzHistogramCnvGauss (WlzObject *histObj, double sigma, int deriv) |
| Convolves the given Woolz histogram object's histogram bin values with a Gaussian, 1st derivative of Gaussian or 2nd derivative of Gaussian convolution kernel. More... | |
| WlzErrorNum | WlzHistogramRsvGauss (WlzObject *histObj, double sigma, int deriv) |
| Uses an infinite impulse response (IIR) filter to convolve the given Woolz histogram object's bin values with a Gaussian, 1st derivative of Gaussian or 2nd derivative of Gaussian. More... | |
| WlzErrorNum | WlzHistogramSmooth (WlzObject *histObj, int width) |
| Low pass filters the given Woolz histogram object's histogram bin values by convolving them in the space domain with a Gaussian kernel of the given half height full width. More... | |
| WlzErrorNum | WlzHistogramCummulative (WlzObject *srcHist) |
| Modifies the given histogram so that its values are cummulative. More... | |
| WlzErrorNum | WlzHistogramMapValues (WlzObject *srcObj, WlzObject *mapHistObj, int dither) |
| Uses the given mapping histogram with integral bin values to remap the grey values of the given 2D or 3D domain object. The mapping histogram MUST have integral bin values and bins appropriate for all domain object values. More... | |
| WlzErrorNum | WlzHistogramFindPeaks (WlzObject *histObj, double sigma, double thresh, int *dstFeatSz, int **dstFeat, WlzHistFeature feat) |
| Find the peaks and/or troughs of the given histogram. Peaks are found by searching through the 1st derivative (h') of the histogram bin values (h). For a peak. More... | |
| WlzErrorNum | WlzHistogramFitPeaks (WlzObject *histObj, int numDbn, double smooth, double thresh, double tol, int *dstNumMu, double **dstMu, int *dstNumSigma, double **dstSigma, int *dstNumAlpha, double **dstAlpha, double *dstLL) |
| Fit the given Woolz histogram object's histogram bin values using a mixture of Gaussian distributions. More... | |
| WlzErrorNum | WlzHistogramNorm (WlzObject *histObj, double maxVal) |
| Normalise the given Woolz histogram object's histogram bin values to the given range [0-maxVal]. If the given maximum value is 0.0 then the histogram bin values are normalised so that maxVal is equal to the number of bins. More... | |
| double | WlzHistogramBinSum (WlzHistogramDomain *histDom) |
| Computes the sum of the histogram domain's bin values. More... | |
| int | WlzHistogramBinMax (WlzHistogramDomain *histDom) |
| Finds the bin of the histogram domain which has the greatest occupancy. More... | |
| double | WlzHistogramDistance (WlzObject *histObj0, WlzObject *histObj1, WlzErrorNum *dstErrNum) |
| Calculates a distance measure for comparing two histograms. The histogram distance is in the range [0.0 - 1.0] with 1.0 being a perfect match between histograms. The given histograms are not modified. More... | |
| WlzErrorNum | WlzHistogramMatchObj (WlzObject *srcObj, WlzObject *targetHist, int independentPlanes, int smoothing, double minDist, double maxDist, int dither) |
| Modifies the grey values of the given Woolz 2D or 3D domain object so that the resulting object's histogram matches the target histogram object. More... | |
| WlzErrorNum | WlzHistogramEqualiseObj (WlzObject *srcObj, int smoothing, int dither) |
| Modifies the grey values of the given Woolz 2D or 3D domain object so that the resulting object's histogram approximates a uniform histogram. If the specified smoothing is non-zero then the objects histogram is smoothed by WlzHistogramSmooth(). More... | |
