+ *
+ * Decodes raw camera bayer (fourcc BA81) to RGB.
+ */
+
+/*
+ * In order to guard against my advancing maturity, some extra detailed
+ * information about the logic of the decode is included here. Much of
+ * this was inspired by a technical paper from siliconimaging.com, which
+ * in turn was based upon an article from IEEE,
+ * T. Sakamoto, C. Nakanishi and T. Hase,
+ * “Software pixel interpolation for digital still cameras suitable for
+ * a 32-bit MCU,”
+ * IEEE Trans. Consumer Electronics, vol. 44, no. 4, November 1998.
*
- * Decodes raw camera sensor images.
+ * The code assumes a Bayer matrix of the type produced by the fourcc
+ * BA81 (v4l2 format SBGGR8) of width w and height h which looks like:
+ * 0 1 2 3 w-2 w-1
+ *
+ * 0 B G B G ....B G
+ * 1 G R G R ....G R
+ * 2 B G B G ....B G
+ * ...............
+ * h-2 B G B G ....B G
+ * h-1 G R G R ....G R
+ *
+ * We expand this matrix, producing a separate {r, g, b} triple for each
+ * of the individual elements. The algorithm for doing this expansion is
+ * as follows.
+ *
+ * We are designing for speed of transformation, at a slight expense of code.
+ * First, we calculate the appropriate triples for the four corners, the
+ * remainder of the top and bottom rows, and the left and right columns.
+ * The reason for this is that those elements are transformed slightly
+ * differently than all of the remainder of the matrix. Finally, we transform
+ * all of the remainder.
+ *
+ * The transformation into the "appropriate triples" is based upon the
+ * "nearest neighbor" principal, with some additional complexity for the
+ * calculation of the "green" element, where an "adaptive" pairing is used.
+ *
+ * For purposes of documentation and identification, each element of the
+ * original array can be put into one of four classes:
+ * R A red element
+ * B A blue element
+ * GR A green element which is followed by a red one
+ * GB A green element which is followed by a blue one
