How to compare two images through golden Template analysis?

Hi Dibya,
you can skip the pattern matching part if it's not interesting to you. Only look at the "GoldenTemplate"-part.
I can't (and will not) look at the example in more detail, but generally such examples are given with block diagram...

hey frens..i m building a motion detector in java....the problem is this, i have two bufferedimages from webcam...these are consecutive images taken from webcam...i need to compare these two images to check for any changes....i have no idea how to do this...i m trying getRGB() method for this purpose but i think i m not correctly applying it....
so if anyone have any idea how to do this..plzz reply...Take the RGB value from the second image and subtract it from the first.
If the values are the same, the result will be 0 (or black). If the values are different the result will be 0 < x < 255 and the result will be closer to white.
This works really well for black and white images. -
How to compare two images and display the difference on Front Panel

IMG_2118.JPG 1650 KBThe missing thing. You have to keep in mind that what you see is not the same as the camera sees.
So when using IMAQ Substract it gives you the difference of the value of every single pixel!
In order to find the mouse as only difference you have to manage that every other pixel value stays the same, e.g. with a proper lightening.
At the other hand you can combine different filters or alogorithms to get the object, e.g. if the object is darker or brighter then everything else in the image you could use a threshold and then use morphologic operations to get the objects size and position.

Hai Java Guys,
How to compare two images using java.If any thing different at any place ,we have to give details of that pixel.It is GIS project.If anybody know solution for this plz let me know.Thank you in asdvance.
BashaIf the two images are represented as java.awt.Images and have the same scale you can use the java.awt.image.PixelGrabber to obtain an array of the pixel values for each image. Compare the values of these two arrays, and you know where in the images you have differing pixels.

How to Compare Two Camera's capture Image in j2me
i want to know ,how to compare two Camera's capture image in j2me,
in my midlet application i used MMapi to access Camera.& capture two image through Camera. Then i want to store new image instead of previous one in mobile phone memory.
Please tell me how that comparing will done.
thanks in advance.Hi,
I didn�t know about the image comparison, but here is one more idea to store the new picture, whenever you captured the picture take the time and when you take another picture compare the times of both pictures then save the picture with latest time.
But there is one flaw in this approach, if user explicitly changed the time and captured the pictures it won�t work properly.

How do we compare two images in labview?
I have created a back end code which is comparing two images using LABVIEW.i have used a comparator and put a tolerance factor which will help me filter out almost same images.the problem i am facing is that on subtraction of the given two images i am getting a completely random output with noise surrounding the parts of the image which are being compared.Also the tolerance percentage i have given has not been working very effectively.Kindly let me know if there is an easier solution to my task or what needs to be done
Thank youCan you post your code?

I attempted to compare two strings whether they are equal or not. They should return true if both are equal.
One string is based on Taxonomy's Term (i.e. Term.Name) whereas other string is based on String object.
The problem is that both strings which seem equal return false instead of true. Both string values have different special characters though their special characters are & and &
Snapshot of different design & same symbols:
Is it due to different culture or language?
How to compare two strings whether both are equal while ignoring the difference in special characters (& vs &)?Hi Jerioon,
If you have a list of possible ambiguous characters the job is going to be easy and if (& vs &) are the only charracters in concern awesome.
You can use the below solution.
Before comparing pass the variables through a replace function to standarize the char set.
$Var = Replace($Var,"&","&")
This is going to make sure you don't end up with ambiguous characters failing the comparison and all the char are "&" in this case.
Similar technique is used to ignore Character Cases 'a' vs. 'A'
