#define align

#define BLUR_SHIFT   24

#define COP	(		c,
			j,
			x,
			op
	)

Value:

h_coarse[ 16*(n*c+j) + (x>>4) ] op; \
    h_fine[ 16 * (n*(16*c+(x>>4)) + j) + (x & 0xF) ] op;

#define CV_MINMAX_8U	(		a,
			b
	)		(t = CV_FAST_CAST_8U((a) - (b)), (b) += t, a -= t)

#define HOP	(		h,
			x,
			op
	)

Value:

h.coarse[x>>4] op; \
    *((ushort*) h.fine + x) op;

HOP is short for Histogram OPeration. This macro makes an operation op on histogram h for pixel value x. It takes care of handling both levels.

#define MEDIAN_HAVE_SIMD   0

#define N   16

#define UPDATE_ACC01	(		pix,

Value:

        int p = (pix);                  \

struct align ( 16  )

read

This structure represents a two-tier histogram. The first tier (known as the "coarse" level) is 4 bit wide and the second tier (known as the "fine" level) is 8 bit wide. Pixels inserted in the fine level also get inserted into the coarse bucket designated by the 4 MSBs of the fine bucket value.

The structure is aligned on 16 bits, which is a prerequisite for SIMD instructions. Each bucket is 16 bit wide, which means that extra care must be taken to prevent overflow.
