Creates a signature from the given parameters.
input | the CIE Lab converted pixels of an image. Assumed to be N x 3, where N is the number of pixels of the image and 3 are the axes of CIE Lab (L,a,b) |
cellSize | The minimum cell size where subdivision stops. A smaller cell size typically results in more features of the signature |
threshold | All clusters with a relative pixelCount (= pixelCountCluster / pixelCountImage) below this threshold are discarded. E.g. a threshold of 0.001 results in discarding clusters with a relative pixelCount of 0.1 % or less to be discarded. A higher threshold results in a smaller feature count, but delivers non-optimal results. |
