| edgefr | Calculate edge frequency of the image |
| -in <image> | input image |
| -fout <result> | result field |
| [-d <dist>] | distance |
| fractald | Calculate fractal based features from the image |
| -in <image> | input image |
| -dout <result> | result data frame |
| [-pnts <points>] | number of points used |
These commands calculate some features directly from the image. Command edgefr gives out a field containing one scalar. Command fractald gives data frame containing three fields: H, s and res. Length of each field is one. H is the angular coefficient of the fitted line, s the constant and res tells the residual of the points in the logarithmic space. (H is linearly related to fractal dimension.)
