#51 Re: Help Me ! » How to get the area of bin from 0 to 6 if frequency of bins are given » 2012-09-07 23:39:38
Hi tina123;
I do not know. But aren't we still working on the histogram?
yes we are still working on histogram .
Can we get energy from histogram ?
thanks

Hy bobbym,
How can we get energy from histogram ?
like if we have high frequecny --> high energy
low frequency --> low energy .
Also how can we get probability from frequency distribution histogram
but how can we get energy and probability from histogram ?
Any idea .
please help thanks

Sorry .. probably its a stupid question but important for me .
I always have confusion that in real line.
-1 < -2 is true or
-1 > -2
Which is true ?

hmm i see . i got it .
So how about to get the 1st moent,.
I think the quantity that i computed that 1st moment not area . sorry .
also how can we get variance ?
#55 Re: Help Me ! » How to get the area of bin from 0 to 6 if frequency of bins are given » 2012-09-06 22:51:58
okkkk Well i think if we use " area under the curve " from calculus .
then area calculation would be from bin 5 to bin 10 ..
how ???
Well we have interval between bin 5 to bin 10 .
so we have total 5 , 6 , 7 , 8 , 9 , 10 intervals in bin range 5 to 10 .
and frequency corsponding to each bin is calculated.
so we get area .
A = frequecny1 * bin [5] + frequecny2 * bin[6] + .....frequecnt5*bin[10]
the sum will be our area .
Right ? ?

If we have data of 352* 288 dimension. and data is represented as histogram with 20 bins . where Each bin have from 0 to 9 . and the frequency of each bin is given below.
255 , 70 , 60 , 50 ,10 , 5 ,4 , 4 , 60, 50 , 30 , 10 , 5 , 2, 2 , 1 , 0 , 5 , 3, 3
The issue is : I need to find area from
bin 7 to 13 : frequency are 60 ,50,,30,10,5
How to do that ?
Area meant number of data. like 3*3 . area will be 9.
That meant area is number of data . Since frequency represent the occurence of pixels .Can we say that area will be sum of frequency ?
Please help me to get the area of bin from 7 to 13 in which frequency are :
60 ,50,30,10,5
Please guide me thanks
Edited:
one way is defined in calculus i-e " Area under the curve . "
see Finding Areas using Definite Integration in this link : http://www.intmath.com/integration/3-area-under-curve.php
Now in our case we have low bound is i = 7 and upper bound i = 13 .
then area would be f(b) - f(a) = 13 - 7 = 6
Area could not be 6 .. its wrong .
How can we get area under the histogram curve .
thanks

hi tina123
Sorry but some of your posts don't seem to be getting the responses you want.
It would help if you gave us some background to explain what you are trying to do.
For this problem I think you want to identify the maximum frequency from a frequency table and make it zero instead. If I'm correct then you are asking for a computing code routine to find a maximum.
What computer language are you using ?
Bob
Well its my research. I do't wanna post any question regarding it . But since i need discussion and help to take a good decision. so i am here to post my queries .
If any one have interest in computer vision then please help me via email. Its my humble request.
Anyway, I am using c++ . I can't explain my queries in detail . I would like via email . So please if any one have interest then please let me know ,.

hi tina123,
If you look at this page:
http://www.mathsisfun.com/definitions/histogram.html
you will see you require a range of data for each frequency to make a histogram.
The best you can do with these data is a bar graph.
Please explain where the data comes from.
Bob
Well you make me more confuse .
As far as i understand , histogram is the occurrence Of Pixels .
so ,
0 0 0 0 1 1 5 4 666 1 1 0 0 0 0 0 0 0 0
Now histogram would be like this
Number of occurrence of 0 ==> 12
Number of occurrence of 1 ==> 4
Number of occurrence of 4 ==> 1
Number of occurrence of 5 ==> 1
Number of occurrence of 666 ==> 1
to show it in bar graph,
0 is 12 times .
1 is 4 timse .
4 is 1 times
5 is 1 times
and 666 is 1 times .
so if we wanna get mean of hitogram . we can do like
sum of all occurence / totalbins.
That's what i know .
#63 Re: Help Me ! » get mean location in histogram » 2012-09-02 12:35:14
Hy its 666 ..
Hy wait .. I have to get histogram 1st .
and then get mean from histogram ..
Ok please help me to find histogram of above image .
thanks

Let say we have image data like this .
0 0 0 0 1 1 5 4 666 1 1 0 0 0 0 0 0 0 0
Now histogram would be like this
Number of occurrence of 0 ==> 12
Number of occurrence of 1 ==> 4
Number of occurrence of 4 ==> 1
Number of occurrence of 5 ==> 1
Number of occurrence of 666 ==> 1
mean : 12 +4 +1 +1 +1 / total number of points.
mean = 19/19 == > 1
Now issue is i wanna show mean in color form in histogram .
but how can we get location of mean in histogram like in x bins and y probability ?
Where will be mean locate?

I have histogram of colors from 0 to 20 .
My image is like blackground and two the most nearest object exist in the image.
I need to segment skin colored object like hand or face from the image .
Conceptually, the static background object would be at color 0 with high probability because my background is black. and some where the two most nearest object found at hue shown in the images

Hy bob 0255 is data value.
What do you meant by this
you want (i) compute the nearest neighbour for every value (ii) then find the maximum?
I did not clearly understand .
Do you mean find the maximum of (i) and (ii) . Is it ?
