+/*
+    We need to retrieve image from the Scilab environment
+    We do this by getting a List of 2-D matrices. The size of the list, in our case is known(either 3 or 1,
+    3 for a coloured image and 1 for a grayscale image), hence we do not require the dynamic capability of a list.
+    Incase of a 3-channel image, the first matrix will be a matrix with dimensions img.rows X img.cols, and will denote the R(red)
+    values of the image. Similarly, the second will have the G(green) values, and the third will have B(blue) values.
+    For a single-channeled image, we will have only a single matrix
