Acanus's profile - activity

Hi everyone, I'm trying to make a histogram specification/fitting/matching to make the illumination of an image look like a model image ( the model image is the average of several image).So i want to know if OpenCV already have the function to do this? If not, can someone give me some advice on how to make the histogram specification/fitting/matching ( i want to normalize the illumination, but Histogram equalization not work well). Here is the wiki page of histogram specification/fitting/matching: http://en.wikipedia.org/wiki/Histogram_matching

try replace CvSeq *firstcontour = NULL with CvSeq *firstcontour =0

is there any function in openCV that help me calculate ring projection of an image or i have to write it myself? If i have to write it, can some one help me on writing the code that take less computation-intensive.And the algorithm to calculate ring projection is in here : http://machinevision.iem.yzu.edu.tw/vision/tech/Pattern2-color.pdf

Does opencv have any function to calculate circular profiles from an image or i have to write the code myself?

Hi eveyone, i'm new to opencv, and i'm woking on a project that require to segment a color image using meanshift clustering.I tried using meanshift functions in opencv but it not work , can someone write an example of using meanshift for clustering a simple image. Thank for reading this..
