mars_screw

A dataset containing the Intensity and Saturation values of a picture from Mars
taken from Rover Curiosity.

datasets

A clustering algorithm similar to K-Means is implemented, it has two main advantages,
namely (a) The estimator is resistant to outliers, that means that results of estimator are still correct when
there are atypical values in the sample and (b) The estimator is efficient, roughly speaking,
if there are no outliers in the sample, results will be similar to those obtained by a classic algorithm (K-Means).
Clustering procedure is carried out by minimizing the overall robust scale so-called tau scale.

mars_screw function

A list containing information about pixels of a picture form mars mainly
containing red sand and metal form Rover itself. List include:
<ul>
<li>SI_matrix: A matrix with 5063 rows and 128 columns.
Elements 1 to 64 of each row indicate the Saturation values of pixels in a square cell 8 x 8
whereas elements 65 to 128 of each row indicate the cell's Intensity values.</li>
<li>geographic_matrix: An integer matrix of dimension 5063 x 2, each row indicates
 each square cell's locations (x-axis y-axis) at the picture.</li>
<li>screw_index: the index corresponding to the screw observation (screw_index=4180)</li>
</ul>
