kcf's Issues

Using pitor's toolbox fhog

Why have you switched to Piotr's toolbox? Has it proved better performance?
I am asking this because the source code of the toolbox is really hard to read and debug.

耗时问题

理论上来讲,gray特征应该比hog快才对,但我在自己的机器上(i9)对dog1这个序列测试时,发现gray明显慢很多:

gaussian + hog 214
polynomial + hog 283
linear + hog 424

gaussian + gray 116
polynomial + gray 122
linear + gray 259

这个大概是什么原因呢

track fail

how the update function only return a cv::rect, but how to judge the track failed ?

how to give some adviese?

Bug in Init?

if (resize_image_) {
pos_ = FloorPointScale(pos_, 0.5);
target_sz_ = FloorSizeScale(target_sz_, 0.5);
}

Here pos_ is halfed but frame is not. This will lead to a wrong crop .
