Hi,
I am wondering, why alg_noise_tune has a compile time option (last line):
void alg_noise_tune(struct context *cnt, unsigned char *new)
{
struct images *imgs = &cnt->imgs;
int i;
unsigned char *ref = imgs->ref;
int diff, sum = 0, count = 0;
unsigned char *mask = imgs->mask;
unsigned char *smartmask = imgs->smartmask_final;
i = imgs->motionsize;
for (; i > 0; i--) {
diff = ABS(*ref - *new);
if (mask)
diff = ((diff * *mask++) / 255);
if (*smartmask) {
sum += diff + 1;
count++;
}
ref++;
new++;
smartmask++;
}
if (count > 3) /* Avoid divide by zero. */
sum /= count / 3;
/* 5: safe, 4: regular, 3: more sensitive */
cnt->noise = 4 + (cnt->noise + sum) / 2;
}
Doesn't make it sense to have that in motion.conf or camera.conf?
Thanks
Rainer
