Error using + Matrix dimensions must agree.
显示 更早的评论
function allCenters = getDominoValues(BW, bbox, colorIm)
for i = 1:length(bbox)
dominoImage = imcrop(BW, bbox(i,:));
[centers, radii] = imfindcircles(dominoImage, [3 8]);
dominoImageOffset = repmat(double(bbox(i,1:2)), (length(centers)/2), 1);
absoluteCenters{i} = centers(:,:) + dominoImageOffset(:,:);
allRadii{i} = radii;
end
J = colorIm;
for i = 1:length(bbox)
J = insertMarker(J, absoluteCenters{i});
end
imshow(J);
At the moment I am getting the following message "Error using + Matrix dimenions must agree" when "absoluteCenters{i} = centers(:,:) + dominoImageOffset(:,:);" is executed. I have executed the same line in the command script, and I get no error messages.
Does anyone know why this might be happening?
Thanks.

You sure the dimensions of centers and dominoImageOffset are same? You can call them by centers + dominoImageOffset. centers(:,:) + dominoImageOffset(:,:) this is not required.

It is hard to guess remotely, but you can inspect the problem very easy locally:
dbstop if error
Then run your code again until it stops at the error. Now check the dimensions:
size(centers)
size(dominoImageOffset)
As Matlab tells you, they have different sizes.
Perhaps you do not mean length(centers), which is the longest dimension, but size(centers, 1). Never rely on length to pick up the dimension you are meaning.
