compute_safe_ssd_integral_image_c()

static void compute_safe_ssd_integral_image_c ( uint32_t * dst, ptrdiff_t dst_linesize_32, const uint8_t * s1, ptrdiff_t linesize1, const uint8_t * s2, ptrdiff_t linesize2, int w, int h )

static

Compute squared difference of the safe area (the zone where s1 and s2 overlap).

It is likely the largest integral zone, so it is interesting to do as little checks as possible; contrary to the unsafe version of this function, we do not need any clipping here.

The line above dst and the column to its left are always readable.
