请问颜色定位中HSV模型的s和v根据h的值进行自适应变化的原理是什么? mim_sv的自适应公式是怎么得出来的？

Nobody has claimed this yet.

if (H > min_h && H < max_h) {
float Hdiff = 0;
if (H > avg_h)
Hdiff = H - avg_h;
else
Hdiff = avg_h - H;

float Hdiff_p = float(Hdiff) / diff_h;

float min_sv = 0;
if (true == adaptive_minsv)
min_sv =
minref_sv -
minref_sv / 2 *
(1
- Hdiff_p); // inref_sv - minref_sv / 2 * (1 - Hdiff_p)
else
min_sv = minabs_sv; // add

if ((S > min_sv && S < max_sv) && (V > min_sv && V < max_sv))
colorMatched = true;
}

Start with the HSV matching snippet in the issue and locate the implementation of adaptive_minsv, minref_sv, and diff_h in the repository. Trace how the values are configured and used, then document the rationale or derivation of the min_sv formula and its effect on color matching.
