Hi @nishanth patil

The code is available in the example to locate the bright yellow circular objects. You need to adjust the Sensitivity level though.

rgb     = imread("coloredChips.png");
imshow(rgb)
[centersBright, radiiBright] = imfindcircles(rgb, [20 25], ObjectPolarity="bright", Sensitivity=0.95);
hBright = viscircles(centersBright, radiiBright, Color="b");
