hi friends & all contributers!!
i am using a pathgradient brush. i am using a loop to add a single ellipse to add to path and filling that ellipse with path gradient brush and resetting the path.. when the points are too many the application slows down..
Is there any way to make this faster??
Thanks in Advance

Basically: No.
The only things you can do are
1) Use a solid brush instead. This may bring some improvement as the color for each pixel does not have to be interpolated
or
2) Use less points in your path. You wrote that performance degrades when too many points are used. This sounds like your graphics path has far too many points. How many are we talking about here? 100? 1000? Especially a curved path can be defined with far less points and still look good.A while ago he asked me what he should have printed on my business cards. I said 'Wizard'.
I read books which nobody else understand. Then I do something which nobody understands. After that the computer does something which nobody understands. When asked, I say things about the results which nobody understand. But everybody expects miracles from me on a regular basis. Looks to me like the classical definition of a wizard.

Are you drawing directly to the screen or to the memory? I have found out that it is a lot quicker to draw to the Image, then draw that image to screen

Hey guys,i need some help for vehicle recognition system progject, using AForge. i am new in using AForge.
Thanks.

|

can you elaborate your question?
Means, from where you want to recognize vehicle?
Is it static image, video or what?

hmm, sorry bout that, the objective is to identiy different types of vehicles based on certain paremeters like size,etc. Static image.

It sounds difficult
Beacause Images are not taken from same view and you are using size as parameter so there calibration is not match.
its better if you can give image link

hmm. alright, but what if the parameter is car plate. is there any ways?
|
|
|
|

Yes, of course there is. The police use this system, and have done for quite a while.
You may have guessed there is no CarRegistration.Read method just yet in the framework, so for now you'll be wanting to look up image processing, character recognition and half a dozen other things that im sure you'll need but i'll leave as an exercise for you to work out.
|
|
|
|
|
yes,agreed. i will look up the infomation of the few points you mention and try to work soemthing out.Thanks.If i encounter any problems, i will post again.

i have recently edited the software. useing a camera take a photo of the side view of the car and background, use the background to subtract the car in the background using AForge method getting the car image, the car will be measured in pixels. i will repeat this step for lorry and motorcycle. than use switch case method to determine which vehicle has entered the gantry.
any ways to improve it?
thanks.

Hi,
I need to ask once you have created an List how do you compare each of the values within the List against another number?modified on Wednesday, March 10, 2010 12:03 AM

|
|
By looping through the List comparing each of the values to the number..?
|
|
|
|
|
The MSDN documentation contains all the information, in particular it describes List<T>.Find() and List<T>.Contains

Hi,
I've had to go back to the drawing board and I need some help. Below is the code I am using to read a text file which contains around 20 numbers.
The readText Print works as expected showing all of the numbers within the text file.
I need to Print the nearest number (within the text file) that is above another which is a double and I'm not quite sure how?
{
readText = File.ReadAllText("C:\\PIn.txt");
string [] split = readText.Split(new Char [] {' '});
Print(readText);
}

Am I missing something?
1) Find target number in array
2) Get next element in array

there are three steps:
- you come up with a good algorithm
- you come up with reasonable code, implementing said algorithm
- and if you then have a specific problem and a specific question, you post algorithm, code, and problem description on CP, and someone helps you out.
