Hi,

Anybody knows how to make hue distance histogram with opencv c++?

thanks for the answer.. :D

Hi..

I would like to develop an object tracking like a paper below:

[1] Li, J., Zhang, J., Zhou, Z., Guo, W., Wang, B., & Zhao, Q. (2011, October). Object tracking using improved Camshift with SURF method. In Open-Source Software for Scientific Computation (OSSC), 2011 International Workshop on (pp. 136-141). IEEE.

in this paper, the new algorithm being able to adjust the thresholds of S and V adaptively against the environment changes. Specifically, when under a strong illumination, the algorithm ignores those pixels with high S values, and when under weak illumination it ignores those with low S.[p:138]

Anybody knows how to determine an image is under strong or weak illumination in OpenCV? What value should I get to represent an image is under strong illumination or weak illumination?

Thanks in advance

Hi..

I would like to develop an object tracking that using Camshift + SURF or SIFT Feature..

I've read on some forums about object tracking with camshift + SURF or SIFT feature, discusses the general steps:

1. Detect interesting object using keypoint (SURF) or any other approach
2. Get bounding rectangle of object and pass it as input for object tracker (e.g. Camshift)
3. Use object tracker unless object will not lost.

but after I learned Camshift, SIFT, and SURF, I am confused how to use the SIFT or SURF feature as an input to Camshift tracker...

Anybody knows how to using SURF or SIFT feature as an input to camshift? Do you have any hint?

Thanks in advance
