A dataset containing the Intensity and Saturation values of a picture from Mars taken from Rover Curiosity.
A list containing information about pixels of a picture form mars mainly containing red sand and metal form Rover itself. List include
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.
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.
screw_index: the index corresponding to the screw observation (screw_index=4180)
1 2 3 4 5 6 7 8 9 10 11 12 13 14
