When you apply threshold on image (at least the one implemented in OpenCV) you get image with one channel. If you are talking about yellow, than you have multi-channel image. How this happened?
Step 1: Use findContours function to find all objects in image (single channel binary image).
Step 2: Use contourArea function on each contour found in step 1 to find the largest one.
Step 3: Use moments function to find centroid of your contour.
