Facial Recognition Using c# & EMGU CV Accuracy Problem

I have project code to create a face recognition system using EMGUCV. I have trained the database with 2 people. When the webcam detects those people and able to show the name correctly but the problem is the third person whose do not exist in trained database detect by webcam, it will take the nearest face and display the name on it instead of show "Unknown". How can I improve the accuracy? I have tried to change the threshold value but didn't help. What's going wrong?

I have been searching solution for this but still having error in my update query at the time of image upload

This is my update button click event:
private void btnUpdate_Click(object sender, EventArgs e)
{
try
{
if (ValidateAll())
{
SetValues();
_objHotel_EL.HotelID = HotelId;
_objHotel_EL.CommandName = "Update_HotelDetails";
int update = _objHotel_BL.Insert_Hotel(_objHotel_EL);
if (update > 0)
{
MessageBox.Show("Hotel Details Updated");
ClearAll();
}
else
{
MessageBox.Show("Already Exists");
ClearAll();
}
}
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
}
here's my code which is used to set and upload image and other parameters:
private void SetValues()
{
_objHotel_EL.HotelName = txtHotelName.Text.Trim();
_objHotel_EL.PhoneNo = txtPhoneNo.Text.Trim();
_objHotel_EL.Address = txtAddress.Text.Trim();
_objHotel_EL.EmailId = txtEmailId.Text.Trim();
_objHotel_EL.WebSite = txtWebsite.Text.Trim();
_objHotel_EL.CurrID = CommanValue.CurrID;
if (flag == 1)
{
_objHotel_EL.BinaryImage = ReadFile(labelImagePath.Text);
_objHotel_EL.ImagePath = labelImagePath.Text;
}
else
{
if (imageData == null)
{
string path = System.AppDomain.CurrentDomain.BaseDirectory.Replace("\\Debug", "");
path = path.Replace("\\bin", "");
path = path.Replace("\\x86", "");
path = path + "Images\\NoImage1.png";
labelImagePath.Text = path;
imageData = ReadFile(labelImagePath.Text);
_objHotel_EL.ImagePath = path;
}
_objHotel_EL.ImagePath = labelImagePath.Text;
_objHotel_EL.BinaryImage = (byte[])imageData;
}
}
This is code of ReadFile:
private byte[] ReadFile(string strPath)
{
byte[] data = null;
FileInfo fInfo = new FileInfo(strPath);
long numBytes = fInfo.Length;
FileStream fstream = new FileStream(strPath, FileMode.Open, FileAccess.Read);
BinaryReader br = new BinaryReader(fstream);
data = br.ReadBytes((int)numBytes);
return data;
}
Please help me out because its giving me an error The conversion is not supported. [ Type to convert from (if known) = nvarchar, Type to convert to (if known) = image ] while i am using sql server compact in visual studio 2012 using c#.
In database side datatype of image is image.

Actually I tried with myself after using SqlCeCommand parameters and its solved.
Here is the code.
if (objEL.CommandName == "Update_HotelDetails")
{
DataTable dt = SqlHelper.ExecuteDataset("SELECT HotelName, HotelID FROM Master_Hotel WHERE (HotelName = '" + objEL.HotelName + "') AND (HotelID <> '" + objEL.HotelID + "')").Tables[0];
if (dt.Rows.Count == 0)
{
string str = ("UPDATE Master_Hotel SET HotelName = #HotelName, PhoneNo = #PhoneNo, Address = #Address, EmailId = #EmailId, Website = #Website, Image = #Image,ImagePath = #ImagePath WHERE (HotelID = #HotelID)");

C# emgu saving an emgu captured image to a MySQL database

I am able to convert the emgu image format to a byte string and this does save on the MySQL database with this code, but the image is saved in a format not even recognized by windows image viewer
string myConnection = mydbconnection;
MySqlConnection myConn = new MySqlConnection(myConnection);
myConn.Open();
Bitmap image = trained.ToBitmap();
MemoryStream ms = new MemoryStream();
image.Save(ms, System.Drawing.Imaging.ImageFormat.Bmp);
byte[] picture = ms.ToArray();
string formmattedPic = Convert.ToBase64String(picture);
MySqlCommand cmd = new MySqlCommand("INSERT INTO sql434250.facialid (timeanddate,photo1) VALUES(#named,#Trainedface)",myConn);
cmd.Parameters.Add("#named", MySqlDbType.VarChar).Value = named;
cmd.Parameters.Add("#Trainedface", MySqlDbType.Blob);
cmd.Parameters["#Trainedface"].Value = formmattedPic;
cmd.ExecuteNonQuery();
label4.Text = named.ToString();
myConn.Close();
}
My problem starts when I try to add the final image formatting I get a system not supported exception on the fs = new FileStream(named, FileMode.Open, FileAccess.Read); line, I am not sure how the filestream works, (new to C#) so please forgive me for any obvious mistakes in the code, for information I am on a windows 8 os, vs 2013
as here:
FileStream fs;
BinaryReader br;
byte[] ImageData;
**fs = new FileStream(named, FileMode.Open, FileAccess.Read);**
br = new BinaryReader(fs);
ImageData = br.ReadBytes((int)fs.Length);
br.Close();
fs.Close();
MySqlCommand cmd = new MySqlCommand("INSERT INTO sql434250.facialid (timeanddate,photo1) VALUES(#named,#Trainedface)",myConn);
cmd.Parameters.Add("#named", MySqlDbType.VarChar).Value = named;
cmd.Parameters.Add("#Trainedface", MySqlDbType.Blob);
cmd.Parameters["#Trainedface"].Value = ImageData;
cmd.ExecuteNonQuery();
I am able to take converted images saved on my pc and manually download via the MySQL site the images these images do work with the software, so to my shame I know its a coding error.
added database table as follows:
CREATE TABLE `**yourdatabase**`.`facialid` (
`id` int( 11 ) NOT NULL AUTO_INCREMENT ,
`timeanddate` varchar( 30 ) NOT NULL ,
`photo1` longblob NOT NULL ,
`code1` varchar( 50 ) NOT NULL ,
`code2` varchar( 50 ) NOT NULL ,
`code3` varchar( 50 ) NOT NULL ,
PRIMARY KEY ( `id` )

I was able to solve my question, I don't know what I did wrong but with a little copying here and there the following code works, what I have done is first stored the image to a local application file and used this file location in the file stream.
named = DateTime.Now.ToString("dd-MM-yy HH:mm:ss:ms");
TrainedFace.Save(Application.StartupPath + "/Temp/face1.bmp");
string dated = DateTime.Now.ToString("HH:mm:ss:ff dd-MM-yy");
label4.Text = dated;
//Show face added in gray scale
imageBox1.Image = TrainedFace;
trainingImages.Add(TrainedFace);
labels.Add(label4.Text);
byte[] imagepic = null;
FileStream fsstream = new FileStream(Application.StartupPath + "/Temp/face1.bmp", FileMode.Open, FileAccess.Read);
BinaryReader br = new BinaryReader(fsstream);
imagepic = br.ReadBytes((int)fsstream.Length);
string myConnection = "datasource=sql4.freemysqlhosting.net;port=3306;user=sql434250;password=lE3!lQ5*";
MySqlConnection myConn = new MySqlConnection(myConnection);
MySqlCommand SelectCommand = new MySqlCommand("INSERT INTO `sql434250`.`facialid` (`id`, `timeanddate`, `photo1`) VALUES (NULL, #dated, #IMG);", myConn);

myReader = SelectCommand.ExecuteReader();
while (myReader.Read())

ArgumentOutOfRangeException was unhandled?

Here is my case: i can retrieved the data from the database, but when i run the program and filled up the Quantity column (on the third line), the error says: index was out of range. Anyone know why is this happen? (When i tried to fill the Quantity column (on third line), the error appeared) <-- shown in the picture below.
Here is the images of my program:

Here is my problem: "i am confuse, when i try assign a value for "textBoxAllTotalContainer.Text = textBoxTotalContainer[0][0].Text", the code is working. but, when i tried "textBoxAllTotalContainer.Text = textBoxTotalContainer[0][one(1)]", the screen stucked in there (I have to stop debugging from Visual Studio)"
textBoxTotalContainer contains 17 textboxes, therefore, i used [0][0] to [0][16], and textBoxAllTotalContainer contains 1 textbox, so i just used textBoxAllTotalContainer.Text
Note: "Keyword (one), it suppose to be "1" <-- number, i wrote (one), because when i tried changed the [0][(Here supposed to be "1")], the text automatically changed to linked image"
Issue: **"When i tried the code
else if (textBoxQuantityContainer[0][0].Text == "1")
{
textBoxTotalContainer[0][0].Text = textBoxSubTotalContainer[0][0].Text;
textBoxAllTotalContainer.Text = textBoxTotalContainer[0][0].Text;
}
the textbox for alltotalcontainer is on (Total on Rp, the textbox is on after words) in the image shown above, the textboxes for subtotal is on (Sub Total on Rp), the textboxes for totalcontainer is on (Total on Rp, the textboxes are on below words), the textboxes for quantitycontainer is on (Quantity). In code above, shown that textbox 1 on textboxtotalcontainer are same with the textbox 1 on subtotalcontainer, and alltotalcontainer is same with totalcontainer.**
But, below code it not working, and the screen stucked on there (the mouse dissappear and i cant do anything, unless i press SHIFT + F5 on Visual Studio):
else if (textBoxQuantityContainer[0][1].Text == "1")
{
textBoxTotalContainer[0][1].Text = textBoxSubTotalContainer[0][1].Text;
textBoxAllTotalContainer.Text = textBoxTotalContainer[0][1].Text;
}
Thanks

You get that error when you try to access an element in a collection that doesn't exist.
For example, if you have a list of strings...
List<string> myList = new List {"one", "two", "three"};
...and try to access the fourth element with myList[3], you'll get that error.
Either textBoxAllTotalContainer[0][2] doesn't exist, or textBoxTotalContainer[0][2]. Can't tell from the error in your picture. Place a breakpoint on that line and check both objects.

Looks like your stop condition is wrong.
you have the following code for initializing textBoxAllTotalContainer:
//****TextBox for Total All****
for (int y = 0; y <= 1; y++)
{
textBoxAllTotalContainer.Add(new List<TextBox>());
textBoxAllTotalContainer[0].Add(new TextBox());
textBoxAllTotalContainer[0][y].Size = new Size(175, 50);
textBoxAllTotalContainer[0][y].Location = new Point(1150, 575);
textBoxAllTotalContainer[0][y].TextChanged += new System.EventHandler(this.textBox_TextChanged);
Controls.Add(textBoxAllTotalContainer[0][y]);
}
Note that the loop is itterating only twice.
Therefore textBoxAllTotalContainer[0][0] and textBoxAllTotalContainer[0][1] are created.
but when you try to access textBoxAllTotalContainer[0][2] you hit the exception because the location is really out of the list's range as the exception specifies.

ASP.NET fileupload doesn't work in server

This code run in my loclhost but doesn't work in server. FileUpload1 has no file in server

I think it's wrong with your
newBMP.Save(Server.MapPath("~/resimler/olkeler/" + fileName.ToString() + fileExtension));
I think you shall loose the ~
I write:
profilPic.SaveAs(Server.MapPath(#"images/people/") +
profilPic.FileName);
from here:
<asp:FileUpload ID="profilPic" runat="server" />
