Compare The Degree Of Similarity Between Two Or More Images?

Jun 15, 2011

I am capturing images from a webcam and I have to compare the degree of similarity between two or more images. that is... which two images are the closest match.

I know I cannot compare the pixels...so how do i go about it?

I am using Visual basic 2010 on Win7

This comparison need to be sufficiently fast. Within 2-3 seconds.

I was looking into pixel by pixel comparison. but webcam pictures as I understand do have slight changes between frames(disturbances).

I am working on recognizing hand gestures...which would in turn control a small mechanical crane...

for example a thumbs-up sign would mean a signal for crane to be switched on...and a full palm shown would mean a stop your work sign.

I plan wearing a white glove against a black background.

I also have ideas like dividing the screen into a 10x10 matrix.

.net - Find Row Index On DataTable?

Feb 6, 2012

Is it possible to get the row index of a DataTable so that you can access the previous and next row? For example I have a DataTable that contains two columns ChapterTitle and PageURL. This is for a table of contents of a book. ChapterTitle is the chapter name and PageURL is an HTML page that contains the chapter (chaptername.html). When going into one chapter of the book I want to be able to tell which is the next and previous chapter.

After finding the chapter that I'm currently in how can get the next and previous rows?

ChapterTable.Select("PageURL = '" & PageURL& "'")

Find The Maximum Value Of A DataTable?

Jun 20, 2012

I have been very stumped by this one. I have a fairly large (~1500 x ~1000) DataTable of positive and negative integers only that I acquired from a .csv file. For my program, I need to find the maximum value of the entire table, not just in a single row or column. Optimally, the code would be short and sweet, but that's not always the case ;).

The name of my DataTable is BeamMap and I am trying to return a value of MaxValue (already declared as an integer). I can post the code I have for creating the DataTable upon request.

Extra Credit: (not really)

Is there a way to quickly find the location (ie., row,column) of said maximum value? So far, all of the examples I've seen check cell by cell for a predetermined value, which is rather inefficient for the number of data points that I have.

Find A DataTable Row By Column Value Using LINQ?

Jan 7, 2012

I have a Dynamic DataTable Created at runtime. The Setup is like so

Id | Name | Age
-----------------
3 | Mike | 21

8 | Sara | 34

What I am trying to do is come up with a linq statement I could use to find and update specific rows.

Such as a statement to change AGE to '33' WHERE ID = '3'

My code So far is:

-[VB.NET]-
Dim MyRow As DataRow = From column In MyTable.Rows Where column("Id") = 3
MyRow(0)("Age") = 33

I've put this code under the DatagridView_CellEndEdit event

The Problem: The 'data_row edited' variable doesn't get initialized when exiting the cell in edit mode using the keyboard (ie: pressing the down/up arrow).If I use the mouse it works as expected. Why is this ?

Generic List Equivalent Of DataTable.Rows.Find Using .NET?

May 8, 2009

I am converting DataTables to a generic list and need a quick and easy way to implement a Find function. It seems I am going to have to use a Predicate. Upon further investigation, I still can't seem to re-create the functionality. Private Function ByKey(ByVal Instance As MyClass) As Boolean Return Instance.Key = "I NEED THIS COMPARISON TO BE DYNAMIC!" End Function

Dim Blah As MyClass = MyList.Find(AddressOf ByKey) But I have no way to pass in a key variable to this predicate to do the comparison, as I used to do with DataTable..Dim MyRow as DataRow = MyTable.Rows.Find(KeyVariable) How can I setup a predicate delegate function in VB.NET to accomplish this?

Do not recommend LINQ or lambdas because this is question is regarding .NET version 2.0.

Database - Find Average Of A Specific Number Of Rows/columns In Datatable And Store To Array?

Jun 21, 2012

I am trying to program a noise reduction algorithm that works with a set of datapoints in a VB.NET DataTable after being helped with my other question. Basically, I want to take two integers, a coordinate value (yCoord for example) and a threshold smoothing value (NoiseThresh), and take the average of the values in the range of (yCoord - NoiseThresh, yCoord + NoiseThresh) and store that number into an array. I'd repeat that process for each column (in this example) and end up with a one-dimensional array of average values. My questions are:

1) Did anything I just say make any sense ;), and

2) Can anyone help me with the code? I've got very little experience working with databases.

Datagridview Bound To A Datatable Setting Its Datasource Property To The Datatable

I have a datagridview bound to a datatable setting its datasource property to the datatable. I would like to have a child form that contains a list of columns associated with the datatable that contains a checkbox that will allow the user to hide and show the columns ( I do not know the best control to use here) (I assume this is the easy part as All i need to do is loop through each of the datatable's columns to get the column name)

now I would like save these visible columns on some event like form_closing so that the next time the user opens the form up it will remember the settings

Get Subset DataTable From Main DataTable, But Preserve Primary Key & RowErrors?

Apr 16, 2012

I came across a problem with using a BindingSource as my DataGridViews.DataSource. Whenever I applied a filter to a column in the BindingSource and the user makes changes that don't match the column filter the DataGridViewRows would automatically disappear. A similar thing would happen when applying a Sort to a column. If the user made any changes the DridGirdViewRows would automatically sort causing rows to be moved around. This was not ideal for my application and there isn't anyway to stop this from happening with the BindingSource.

To correct this issue I have to use subsets of data. I use a DataView to apply the filter and sort to the main DataTable, which creates the subset DataTable.The problem is when I use the DataView.ToTable method I loose the Primary Key and RowError information. So I have to reapply this information everytime the user filters or sorts the DataGridView.Is there a better way to get a subset DataTable?[code]...
