thank you so much Andol, it was my honour when you replied to me when i’ve just asked, actually, i’m taking a thesis with opencv, but i don’t really know much about iit, i am trying to recognise the basic color as you told, but i don’t really know what to do at first in the code, could you help me with the way to solve the problem. i mean the algorithms.
thank you for your time.

It is the full code, but, some parameters such like the source image and target colour detection need to be adjusted due to different application environments. Have another try, might work with different parameters.

hi Andol, i find that this program is very useful for the people who want to start with opencv, but i wonder that if the code in pdf file is full, i debug it, but there is nothing happen, would you mind if i ask you to tell me the way to run this program. I’m a new comer with opencv. For example: which lib we have to add to input to the input (linker) in the project properties… I’ve added the lib from Opencv to C++.(include, Lib already)
thanks a lot for your help!!!

hi,ur code was very useful for me ,i need to know the position of this object
for(int i = 1;i < sz.height; i++)
{
for(int j = 1;j {
if (cvGet2D(hsv_mask,i-1,j).val==s.val &&cvGet2D(hsv_mask,i,j).val==s.val&&cvGet2D(hsv_mask,i+1,j).val&&cvGet2D(hsv_mask,i,j-1).val==s.val&&cvGet2D(hsv_mask,i,j).val==s.val&&cvGet2D(hsv_mask,i,j+1).val)
{
select_object=1;

selection.width=30;
selection.height=30;
selection.x=i;
selection.y=j;

}
i trying this code but it fails
