There are several article about image processing here at codeproject, why don't you read them?

Hi friends,
I have created a toolbar for IE but the problem is this that when i run this setup on different machine it is not visible by itself.I have to turn on it by clicking on tool bar.
So my question is this that is there any property so that at the time of installation of this tool bar it make an entry in registry so it will come automatically.
Thanks,

Hi guys,
I wrote this:
string cmd = "select fid,fval from x";
OdbcDataAdapter da=new OdbcDataAdapter(cmd,this.odbcConnection1);
int i = da.TableMappings.Count;
and I found da.TableMappings.Count was always zero.
I don't want to use da.TableMappings.Add() function to add table mapping and columns mapping.
Are there any functions in ADO.NET that can generate the mapping info base on a odbcDataAdapter instance?
Anything you can help it would be appreciated.

i have a black and white image, i need to quickly scan the entire image for white (255,255,255 RGB) pixels and add then to an array. I have a for loop in a for loop to do this as follows:
<pre
private void trackLane()
{
Bitmap leftLane = new Bitmap(detectLeft.Image);
Bitmap rightLane = new Bitmap(detectRight.Image);
for (int i = 0; i <= detectLeft.Width; i++)
{
for (int j = 0; j <= detectLeft.Height; j++)
{
leftLane.GetPixel(i, j);
rightLane.GetPixel(i, j);
}
}
}
></pre>
Where j is the y axis and i is the x axis, i think there is a more efficient way of doing this, any suggestions?

Hi,
here are some ideas:
1. j <= detectLeft.Height gets executed for every pixel, you'd better store detectLeft.Height in a local int variable
2. executing a lot of GetPixel() calls tends to be slow since each time the coordinates are checked against the image boundaries, and translated into a linear index, something that can be done more easily once one knows they all get handled sequentially
3. the most practical approach to (2) is by using pointers
4. why do you use 4 bytes per pixel if all it can be is black and white; an array (bools, bytes, ints, ...) or a BitArray would be more economical in space, and hence in speed (assuming your image is say 512*512, it takes 1MB which is about the size of the level 2 cache); less data would run faster.
Maybe you should swith to one byte per pixel (optimum between density and simplicity)
5. there are special code snippets to find the lowest bit set in an integer, this could be much faster assuming a binary image (yours is), and a majority of zeroes.
x & -x results in zero if x is zero, and in an int with exactly one bit set which is also set in x otherwise.
