+ *
+ * The generation of the pattern images is performed with Gray encoding using the traditional white and black colors.
+ *
+ * The information about the two image axes x, y is encoded separately into two different pattern sequences.
+ * A projector P with resolution (P_res_x, P_res_y) will result in Ncols = log 2 (P_res_x) encoded pattern images representing the columns, and
+ * in Nrows = log 2 (P_res_y) encoded pattern images representing the rows.
+ * For example a projector with resolution 1024x768 will result in Ncols = 10 and Nrows = 10.
+
+ * However, the generated pattern sequence consists of both regular color and color-inverted images: inverted pattern images are images
+ * with the same structure as the original but with inverted colors.
+ * This provides an effective method for easily determining the intensity value of each pixel when it is lit (highest value) and
+ * when it is not lit (lowest value). So for a a projector with resolution 1024x768, the number of pattern images will be Ncols * 2 + Nrows * 2 = 40.
