Hi everyone,
I've been trying to implement Haar Cascade car classifer lass in order to detection vehicles in a video. However I can't seem to find anything on this. I'm new to Haar Cascade and EmguCV. Any help would be much appreciated, thanks in advance. All I have been able to find so far is:
public class HaarCascade : ICloneable
{
String path = @"C:\Users\Dylan\car.xml";
HaarCascade cascade1 = HaarCascade.FromXml(path);
Image<bgr, byte=""> frame = new Image<bgr, byte="">(bitmap);
Image<gray, byte=""> grayFrame = frame.Convert<gray, byte="">();
var cars = haar.DetectMultiScale(grayFrame, 1.5, 20, new System.Drawing.Size(10, 10), new System.Drawing.Size(80, 80));
foreach (var car in cars);
frame.Draw((Rectangle)car, new Bgr(255.0, 0, 0), 2);
}

How did you ever hear of "Haar Cascade" if you "can't seem to find anything on (it)"?
I only found 587,000 references.

I tried as
if (radioButton54.Checked)
{
Paragraph soru1 = new Paragraph(label10.Text + " " + radioButton54.Text + radioButton54.Image);
pdfDosya.Add(soru1);
}
but it shows up as System.Drawing.Bitmap at .pdf

I get the employee list from SQL Server problem with fields:
ID: id employee
Employee: name employee
after filter the kernel list dv.RowFilter = "set condition unique 1 recoder" at the command if (dv.Count == 1) at this assignment id and the kernel name is not correct the unique file filter on which it assign the first file in the family list. yourself want to get sample sample already been filter by dv.RowFilter, main syntax in command if (dv.Count == 1) {// chars this again as what ?)
string tmpSQL = "string to get the list employee";
DataTable dt = Conection.FillDatatable(tmpSQL);
DataView dv = new DataView(dt);
dv.RowFilter = "set condition unique 1 recoder";
if (dv.Count == 1)
{
txtIdEmployee.Text = dv.Table.Rows[0]["ID"].ToString();
txtNameEmployee.Text = dv.Table.Rows[0]["Employee"].ToString();
}
else
{
}

It may be early in the morning and I'm still drinking my first coffee of the day, but that makes no sense to me at all.
Please, try copy and pasting the code you are actually using (use the "code" widget to format it)
if (a)
{
b();
}And show sample DB data. Then explain what you expected to happen, and compare that to what did, tell us when it happened, what you did to make it happen, give us any error messages that appeared. Remember that we can't see your screen, access your HDD, or read your mind - we only get exactly what you type to work with.
But from what you have posted so far, I can't even work out when the problem occurs (compilation or run time) much less what the problem itself might be - and so can't even begin to come up with a solution!

The RowFilter property[^] has a defined syntax[^] which you must follow.
"set condition unique 1 recoder" is not a valid row filter.
The rest of your question makes absolutely no sense. I suggest you find a better translator.

You could try this:
DataTable table = dv.ToTable().AsEnumerable().GroupBy(x=>x.ID);
if (table.Rows.Count == 1)
{
txtIdEmployee.Text = table.Rows[0]["ID"].ToString();
txtNameEmployee.Text = table.Rows[0]["Employee"].ToString();
}

Hi Guys,
How can I make below work? 3 radio button is there and whichever is clicked will be added to pdf.
switch
{
case 1 (radioButton54.Checked)
Paragraph q1 = new Paragraph(label10.Text + " " + radioButton54.Text);
pdfDosya.Add(q1);
case 2 (radioButton122.Checked)
Paragraph q1 = new Paragraph(label10.Text + " " + radioButton122.Text);
pdfDosya.Add(q1);
case 3 (radioButton1.Checked)
Paragraph q1 = new Paragraph(label10.Text + " " + radioButton1.Text);
pdfDosya.Add(q1);
}

You can't use switch like that in C#, the format is:
switch (variable)
{
case constantValue1:
...
break;
case constantValue2:
...
break;
default:
...
break;
}You could use a variable to "combine" the radio buttons and the switch on that, but it would be very messy. You would be much better off with an if ... else if ... else instead:
if (radioButton54.Checked)
{
Paragraph q1 = new Paragraph(label10.Text + " " + radioButton54.Text);
pdfDosya.Add(q1);
}
else if (radioButton122.Checked)
{
Paragraph q1 = new Paragraph(label10.Text + " " + radioButton122.Text);
pdfDosya.Add(q1);
}
else if (radioButton1.Checked)
{
Paragraph q1 = new Paragraph(label10.Text + " " + radioButton1.Text);
pdfDosya.Add(q1);
}In the long term, it'll be a lot more readable and maintainable.

Well, technically, this terrible code would work:
switch (true)
{
case true when radioButton54.Checked:
...
break;
case true when radioButton122.Checked:
...
break;
case true when radioButton1.Checked:
...
break;
}
After all, you didn't say it had to be good code.

:shudder:
We should have a detector system that sends code like that direct to "weird and wonderful" so we can abuse it...

It's very useful code: a perfect example of "Just because you can do something, doesn't mean you should".

I do not provide one-to-one solutions here: so sending me a private email requesting further help will not work.
If you want additional help please post the request publically, so all can assist and / or benefit.
