Hi Kosmut, Would you mind posting this example that you tried to use ChanVeseBinarize on? It will help greatly for tips.
As you found out, WatershedComponents typically over-segments, yielding too many "regions" as you call them, or components to follow our terminology. To overcome the issue, you can pre-process the image, or use markers --- the documentation shows...
Thanks for the pointer!
[@chagay chagay][at0] , is this homework? Since I think it's homework, I'll just say that you can cast this problem as an inverse convolution problem, and will leave the explanation open for now. ImageDeconvolve looks reasonable fine: ...
Thanks for reporting Marco. We have become aware of a regression bug in HighlightImage in 10.3. Annoying indeed. On OS X 10.10.5 and Mathematica 10.3, FindFaces works as expected as far as I can tell. The face is detected, and it's the...
Would you mind giving pointers to these "smoothing filter" references? It might be a case of terminology collision with a domain other than image processing.
Yes, that's it.
ArrayFlatten works faster if you can reshape the entire data at once: In[39]:= testData = RandomInteger[{0, 100}, {176851, 4}]; In[45]:= AbsoluteTiming[ res = ArrayReshape[testData, {First@Dimensions@testData, 2, 2}]][[1]] ...
David, If by *amplitudes* you were looking for the vector v above, then you are looking for the second argument returned by KarhunenLoeveTransform. Using the variable names from Jim's example, v and...
Jakie, You want to use FindGeometricTransform with the Method option value "ImageAlign".  This feature is present in version 9 and appears in the future documentation: ...
