circle_hough doesn't seem like a MathWorks developed function. There is a file exchange entry you might want to download to access it. Its here. FWIW the built in Image processing Toolbox function to find circles using hough is imfindcircles.
Hi!
It appears to me that you want to calculate the centroid of the white spot in your image, and using this centroid value as the center, plot a circle of any radius.
The first part of the question, i.e. finding the centroid of the circle can be evaluate as follows â
im = imread('figure.jpeg'); % Your figure
imBin = imbinarize(im);imBin = imfill(imBin, 'holes');BW = regionprops(logical(imBin), 'centroid');imshow(imBin); hold on; plot(BW.Centroid(1),BW.Centroid(2),'bx') The value of the centroid of this image is stored in the variable âBWâ.
The output is -
(I snipped this output to enhance readability)
Coming to the second part of your question, please refer to this link here to get the relevant steps to plotting a circle with a given center and radius.
