Feature | No. of Features | Details |
|---|---|---|
Fractal dimension | 3 | Mean of fractal dimension, standard deviation of fractal dimension, lacunarity |
Ripplet coefficient | 2 | Mean of ripplet coefficient, standard deviation of ripplet coefficient |
Autocorrelation coefficient | 2 | Mean of autocorrelation coefficient, standard deviation of autocorrelation coefficient |
Gray level co-occurrence matrix | 16 | Four set of data values; each set consist of the contrast, homogeneity, energy, and correlation |
Gray level run length matrix | 44 | Short run emphasis, long run emphasis, gray level non-uniformity, run length non-uniformity, run percentage, low gray level run emphasis, high gray level run emphasis, short run low gray level emphasis, short run high gray level emphasis, long run low gray level emphasis, long run high gray level emphasis. Each of the above was calculated for 0, 45, 90, and 135 |
