Problems with colorDistance in SimpleCV

[buzb]

Hi all,

I'm having some trouble with the colorDistance function in simpleCV 1.3.0
called from python 2.7 in Ubuntu 12.04.

target=(212.0, 200.0, 150.0)

distanceImg = img.colorDistance(target)
distanceImg.save('distanceImg.jpg')
img.save('img.jpg')

Calls to colorDistance yield an image that is distorted. I've attached a
copy of the distanceImg (distanceImg.jpg) and a copy of the image (img.jpg)
that was used to derive it.

Is there a good work around to this?

Many thanks, and all the best,

I have never used these functions. Try OpenCV, Mahotas, Mamba, PIL Python
libraries, perhaps. Or you should somehow preprocess image, I think.
Otherwise, use C++ or Java for a better control on a lower level.

What is the colorDistance function meant to measure? Would something
like this do the trick?

Hi,

I have develop version of SimpleCV (https://github.com/sightmachine/SimpleCV)
and I'm getting the following output. I think there was a bug which was
fixed in the develop version. You could upgrade and try it,

Hi Jay,

Many thanks for getting back to me on this. I haven't had a chance to try
your updated code, but your image appears to be what I want. I'll give the
code a try in the next few days and let you know how it goes.

Many thanks, and all the best,

Hi Jay,

This reply has taken a long time to come.

I'm still having trouble with the SimpleCV software. I tried to download SimpleCV from github, but am still getting the distorted output when I use colorDistance function rather than the non-distorted image that you got.

Where can I download the developer version from?

Many thanks, and all the best,

Hi Jay,

Just FYI, I went back to an old version of SimpleCV (9f395163a6 - a July 17th version of SimpleCV), and have solved my problem for the moment.

All the best,
