Hello Could you provide an image and short code example ? If that it not the case then the unit tests would fail https://github.com/scikit-image/scikit-image/blob/master/skimage/feature/tes... Thanks Vighnesh On Monday, November 23, 2015 at 1:21:39 PM UTC-5, Iakovos Halegoua wrote:

Hello there,

I'd like to point out to the documentation authors a minor error in the blob_doh <http://scikit-image.org/docs/dev/api/skimage.feature.html#blob-doh> description. In the Notes section it is stated that: "The radius of each blob is approximately sigma.". As I tested the DoH responses of synthetic blob images, it seemed that the radius of the blob is matched to the scale according to: r = sqrt(2) * s. Could you provide me with some reference on how you calculated the matching scale to be at r = s? I guess this is nothing serious, but it was a little confusing when I first encountered it :P
