Functions

func Calculate

func Calculate(pixels [][]uint64, gridX, gridY uint8) ([]float64, error)

Calculate function generates a histogram based on the 'matrix' passed by parameter.

func Compare

func Compare(hist1, hist2 []float64, selectedMetric string) (float64, error)

Compare function is used to compare two histograms using a selected metric. Histogram comparison references: http://docs.opencv.org/2.4/doc/tutorials/imgproc/histograms/histogram_comparison/histogram_comparison.html
