Hello everyone,
I am wondering what should this patch do? Its description says:
"Calculates a histogram for the specified area in an image, returning
the result in a 1D image."
No other documentation I was able to find about this patch.
It has following parameters: image, extent, scale, count.
Image is clear.
Extent (I think) also is clear - it should describe image area which I
want to use. At the moment I am using extent {0, 0, imageWidth,
imageHeight}
After some tests I have found, that 'count' is responsible for patch
output image width and is histogram bins count.
No idea what scale is for.
I was thinking in same way like Jonathan - I thought that result image
pixels should hold image histogram information: pixels red values for
red channel histogram, green value for green channel and so on.
But the result of this patch is _very_ strange. I am getting image of
dimensions {1, _parameter_COUNT_}. It is always black except sometimes
the right side of image becomes white (when using RGB image as input).
Only few last pixels. If I try to draw histogram by using this image
pixels values, the result is far away from the reality...
So - what information provides this patch and how it should be
interpreted if I want to get some useful information about histogram?
Any information is appreciate.
Jonas S.
