What steps will reproduce the problem?
1. Open iplab
2. Click on the show histogram icon from the toolbar.
3. Now open any image
4. Close the histogram viewer.
5. Close the application.

What is the expected output? What do you see instead?
The program should exit. We get an error message say "Cannot access a
disposed object".

What version of the product are you using? On what operating system?
I am using v2.4.0 on windows XP professional. 

Please provide any additional information below.
The screen shot and the details are available in the attached file.

It is required to simplify polish postfix expressions – evaluate 
functions, which have constants as their arguments, and replace these 
functions with their result.

This library is infinitely useful and I've had some limited success with
using the pre-compiled binaries in VB.NET, however I get errors when I
attempt to use the BlobCount functions. Some simple VB.NET code samples
would be great for those who find C# a little too daunting.

What steps will reproduce the problem?
1. Compile and run the Time Series example with Visual Studio 2005.
2. You will get the run-time error: "Cross-thread operation not valid: 
Control 'currentIterationBox' accessed from a thread other than the thread 
it was created on."

Under VS 2005 you cannot run code that is not thread safe.

It is required to implement Harris corner detector. Some information can 
be found here: 
http://en.wikipedia.org/wiki/Corner_detection#The_Harris_.26_Stephens_.2F_P
lessey_corner_detection_algorithm

does aforge has following functionality

1) automatically crop the image
2) auto deskew the image 
4) hide micr line on check image.

if yes then how to implement 

thanks

It is required to have a possibility to convert expression is postfix 
notation to infix

Elite selection should randomly sort new population, so it will not 
contain all best chromosomes on the top.

The following is a code i wrote to test the Complex object in Aforge.Math. 
Complex[] dx = new Complex[512];
for (int i = 0; i < dx.Length-1; i++)
{
dx[i] = (Complex)(Math.Sin(i));//ERROR????
}
When I run this, the compiler(Visual studio.NET 2005) complains"Cannot 
convert type double to Aforge.Math.Complex".
Has anyone ever encountered this error.

Can anyone upload some more examples(tutorial) on the usage of Math 
functions in this library.
Cheers

It is required to implement Homomorphic filtering.

Useful links:

In DoubleRange.cs and IntegerRange.cs, I think the IsInside function is in
error; Don't really know how it affect the code and examples, I'm just
starting to look at it !

Original:
public bool IsInside( double x )
{
  return ( ( x >= min ) && ( x <= min ) ); // This looks like return x == min
}

Should be (?) :
  return ( ( x >= min ) && ( x <= max ) );

It is required to recalculate fitness value only of new members of the 
population. If input data don't change during solution search, we do not 
need to recalculate fitness of the entire population, what leads to 
decreasing performance.

It is required to implement population shuffling, when new generation is 
generated. Now the feature is implemented in Elite Selection algorithm. It 
is better to move the functionality to Population class and allow to 
enable/disable the function.

In polish postfix expressions it is required to partly (or fully) evaluate 
expression variables - replace variables with their values (for example 
replace $2 variable with its value equal to 3.14)

I need to save trained network to file. The best way how to do it is 
enable serialization Network class.

It is required to develop facility, which allows applying image processing 
filter to part of source image only.

if you remember we discussed it before and you said that removing locks
will increase the performance i think that this is the solution for that

What steps will reproduce the problem?
1. make methods which directly inputs Bitmapdata
2. make class which handles locking and unlocking of images

What is the expected output? What do you see instead?
faster application and image processing

What version of the product are you using? On what operating system?
[13.06.2006] - Version 2.3.0 winXP

Needed Color Reduction Functionality to reduce 24RGB to Indexed Palette 
with needed Colors with/wihout Dithering

Could anyone give me some pointers on how to capture images at 640x480 
instead of teh default 320x240 reoslution?

Many thanks,

It is required to have a possibility to compile polish postfix expression 
to IL code, so it could be called faster.
