Hi,
I'm new in Image Proccessing.
I have an image and I want to parsing Text blocks and picture blocks.
How can I do?
I don't use OCR components. I need algorithm or sample or suggestion.
I'm using a web reference generated from a .wsdl file.
I've also examined the Amazon web service example but couldn't get it working.
Enclosed is an example of the soap request.
Thanking You

Hi. I want to learn that is EmguCVs EigenObjectRecognizers has Recognize() method.But I could not found any information that is using which algorithm.I used it in my thesis and I need to know which technique is using that method.I know it uses Eigen Vector and Eigen Values but I am not sure how it uses it. Is any one know could point me ?
Thanks.
I would like to find an open source example of a code for deterministic annealing. It can be in almost any language: C, C++, MatLab/Octave, Fortran. I have already found a MatLab code for simulated annealing, so MatLab would be best. Here is a paper that describes the algorithm: http://www.google.com/url?sa=t&source=web&ct=res&cd=1&ved=0CB8QFjAA&url=http%3A%2F%2Fvandamteaching.googlepages.com%2FABriefIntroductionToDeterministicAnn.pdf&ei=DiLiS8qZFI7AMozB1JED&usg=AFQjCNHLps7HRWXLNN5rAX5aJ5BsJbcHuQ&sig2=YSokUTOs0UszAFZ9TDiJgQ
What is the best we can do with run length encoding.
http://en.wikipedia.org/wiki/Run-length_encoding Page suggests the time complexity is O(m*n) where m is the number of time the number repeats ..
Is the a more efficient algorithm to do RLE ??
Hi all
I have a question: is there any reference (e.g. paper) with a proof of the planarity of flowchart layouts? Can anyone suggest an algorithm for generating flowchart (planar) layouts?
I know that there are some code-to-flowchart tools out there, but i'm unaware of their internals.
Thanks in advance

How would I smooth a line (UIBeizerPath) or a set of points? Right now it draws it jagged. I read about spline interpolation, could anyone point me to an implementation of this in cocoa or C or give me an alternate line smoothing algorithm.
Hello, I just implemented a SOM algorithm in MATLAB that outputs component planes and U matrix....but i want to be able to calculate sensitivity, accuracy and specificity....how do i go about doing this in MATLAB??....any ideas or useful links would be highly appreciated??
Is there an easy way to get the relative complement of two sets? Perhaps using LINQ?
I have to find the relative compliment of a set A relative to B. Both A and B are of type HashSet<T> but I think the algorithm could be made more general (IEnumerable<T> or even ISet<T>)?
I could use a solution in either VB.NET or C#.
While using
USE mssqltips_tde;
CREATE DATABASE ENCRYPTION KEY with ALGORITHM = AES_256 ENCRYPTION BY SERVER CERTIFICATE TDECert

please help in resolving the same as i need to implement Encryption on my DB
I would like to know if it is technically possible to resize an image at a client-side with javascript (really resize, not just change width and height). I know it's possible to do it in flash but I would like to avoid it if possible. Is there any open source algorithm somewhere on the web?
How can I draw a multi-color randomized unicorn using Logo?
the algorithm is described in balpha's blog, but I don't know which steps to start with to implement it in Logo
Some sites that I am fetching data from are returning UTF-8 strings, with the UTF-8 characters escaped, ie: \u5404\u500b\u90fd
Is there a built in cocoa function that might assist with this or will I have to write my own decoding algorithm.
Hi every body
I am looking forward to find an algorithm to detect a pattern in a given video file. Actually I am going to index moments in a tennis match video at which service (first kick after a goal) is shot.
PS1: sorry for broken English.
PS2: I DO NOT know anything about tennis except that you need a ball to play!!
I need to map out a complex algorithm with lots of conditional options. Need an easy to use flowchart software, preferably free since I need it for just a one time use. Would prefer something lightweight which doesn't eat up all the CPU memory.
Any ideas?
Hi all, I would like to know simple k-means algorithm in java. I want to use k-means only for grouping one dimensional array not multi.
For example,
before grouping the array consists of 2,4,7,5,12,34,18,25
if we want four group then we got
group 1: 2,4,5
group 2: 7,12
group 3: 18,25
group 4: 34
we have a situation that a stream (data from sensor or click stream data at server) is coming with sliding window algorithm we have to store the last (say) 500 samples of data in memory. These samples are then used to create histograms, aggregations & capture information about anomalies in the input data stream.
please tell me how to make such sliding window.
I'm being asked to display a binary search tree in sorted order. The nodes of the tree contain strings.
I'm not exactly sure what the best way is to attack this problem. Should I be traversing the tree and displaying as I go? Should I flatten the tree into an array and then use a sorting algorithm before I display?
I'm not looking for the actual code, just a guide where to go next.
I've seen the numerous questions about counting the number of set bits in a insert type of input, but why is it useful?
For those looking for algorithms about bit counting, look here:

Why on the same machine computing the SHA-1 hash of the same file produces two completely different SHA-1 hashes in windows and inside a msysgit Git bash?
Doesn't the SHA-1 algorithm was intended to produce the same hash for the same file in all OSes?
On windows (with HashCheck):
File hello.txt
22596363b3de40b06f981fb85d82312e8c0ed511
Inside a msysgit's Git bash windows (same machine, same file):
$ git hash-object hello.txt

My program requires at least Linux 2.6.26 (I use timerfd and some other Linux-specific features).
I have an general idea how to write this macro but I don't have enough knowledge about writing test macros for Autoconf. Algorithm:
Run "uname --release" and store output
Parse output and subtract Linux version number (MAJOR.MINOR.MICRO)
Compare version
I don't know how to run command, store output and parse it.
Maybe such macro already exists and it's available (I haven't found any)?
Hi lynn,
Can u pls help me for the below issue.
I have sha1 value in mssql table (Password is encrypted using algorithm SHA1 which provided in Microsoft .Net library) .
I created one php application, in that i need to compare these encrypted value.
Thanks
I noticed most 3d voxel models are actually pretty low resolution, but then are rendered all smoothed out with some sort of interpolation.
Given its ray traced, what is the algorithm used to render it smoothly? Could anybody suggest a book on the topic?
I have set up a class to validate credit card numbers. The credit card type and number are selected on a form in a separate class. I'm trying to figure out how to get the credit card type and number that are selected in the other class (frmPayment) in to my credit card class algorithm:
public enum CardType
{
MasterCard, Visa, AmericanExpress
}
public sealed class CardValidator
{
public static string SelectedCardType { get; private set; }
public static string CardNumber { get; private set; }
private CardValidator(string selectedCardType, string cardNumber)
{
SelectedCardType = selectedCardType;
CardNumber = cardNumber;
}
public static bool Validate(CardType cardType, string cardNumber)
{
byte[] number = new byte[16];
int length = 0;
for (int i = 0; i < cardNumber.Length; i++)
{
if (char.IsDigit(cardNumber, i))
{
if (length == 16) return false;
number[length++] = byte.Parse(cardNumber[i]); //not working. find different way to parse
}
}
switch(cardType)
{
case CardType.MasterCard:
if(length != 16)
return false;
if(number[0] != 5 || number[1] == 0 || number[1] > 5)
return false;
break;
case CardType.Visa:
if(length != 16 & length != 13)
return false;
if(number[0] != 4)
return false;
break;
case CardType.AmericanExpress:
if(length != 15)
return false;
if(number[0] != 3 || (number[1] != 4 & number[1] != 7))
return false;
break;
}
// Use Luhn Algorithm to validate
int sum = 0;
for(int i = length - 1; i >= 0; i--)
{
if(i % 2 == length % 2)
{
int n = number[i] * 2;
sum += (n / 10) + (n % 10);
}
else
sum += number[i];
}
return (sum % 10 == 0);
}
}
