Image processing at High Frame Rate.

Posted By:      Posted Date: October 14, 2010    Points: 0   Category :WPF
 

Hi all,

I am working on an application which performs stamping of HD images at very high frame rate.

AFAIK GDI is the best, but i heard WPF uses Hardware acceleration. 

To make it faster which technology will be better ? 

GDI / GDI+ / WPF ?

Thanks in Advance..

Image processing, determine white space and crop

  

Hi,


I have created a image upload for our ID card system to allow users to upload new images, edit them and submit for approval.  This is all working well with a combination of asp.net (c#) and jquery to give a seemless editor etc.

We have had a few users who I cannot believe have scanned a photo of themself and then just submitted it with the A4 page of white and little photo.


I am wondering if anyone can help with a suggestion on how I could possibly reduce the load of these coming through (I can't believe they can be this stupid), it stipulates UK passport standards.


Would my only option be to check for a single continues colour that occurs and if it reaches a certain percentage point say 60% then to just send back an error stating they need to crop the image.

Can anyone help with providing sample or that I can use to move this one on.


I am still in disbelief on this one.  the other one is they take a photo of whole body and other in it and cut straight down middle chopping the people out but supplying a photo that no use for an id photo card....but that I can't imagine being solved programatically as I need to determine where their face dimensions are and what percentage of the actual photo is taken up by it and if it below a threshold reject it.




Easy image processing(grayscale, sepia, negative, resize, brightness, contrast and opacity)

  
Howdie y'all,

I see a lot of questions in this forum about resizing images. Recently I created a code sample(with downloadable webapp), right here.

The class (downloaded or created) allows for very fast and easy processing of your images. And a lot of problems over here can be solved by simply using that class. I thought it might help to mention the code sample in this forum as well.

Cheers,

Wes

Image Processing project

  

hii everyone,

I want to develop an asp.net application, which deals with editing of any image.

I want my software to have following features -:

1. It should be able to detect the current properties of selected image like contrast,

    brightness, hue, saturation, color and similar stuffs regarding an image.

2. It should be able to modify these properties of the selected image i.e. increasing/decreasing

    the brightness, hue and others.

Where should i begin from..?


Unknown CPU spike during high volume UDP processing

  
I have tried this numerous ways on Windows 7 and always end up with a CPU spike every 10-15 seconds.  I have no idea what is
causing it.  Basically, I am connecting to a UDP port and echoing the received data back out and testing it with 500 packets/sec.  Between spikes, the CPU is at roughly 0%, and the spikes are between 50% and 75%.  Any ideas?  It seems to be down in the ReceiveFrom/ReceiveFromAsync/SendTo functions, since everything else has been systematically tested.




    public partial class MainWindow : Window
    {
        Udp udp;
        public MainWindow()
        {
            InitializeComponent();
            udp = new Udp(7000);
            udp.ReceivedMessage += new Udp.ReceiveHandler(udp_ReceivedMessage);
        }

        void udp_ReceivedMessage(Udp udp, byte[] buffer, int size)
        {
         

Image button Click event is Not fiering after migrating from 3.5 to 4.0 frame work

Image processing

  

Hi friends, I have an image(Jpeg). I want to accept the color code from the user and manipulate the image to get the new image having the supplied color from the original image. Ex. In an Indian flag, there are 3 colors(like color filled bars. Red, White, Green). If I supply red color (FF0000), the new image should be only 1 bar having the red color. How can I do it? How can I manipulate images? Thanks in advance


Error Processing Mining Structure - Errors in the high-level relational engine.

  

Hi community,

I am trying to learn some datamining with SQL Server. I have some demo projects I am trying to run under my test environment: Windows Server 2008 + SQL Server 2008 R2 Enterprise. Sample projects seems to be ok, but when I try to process a mining structure, I get this error:

"Errors in the high-level relational engine. The following exception occurred while an operation was being performed on a data source view: The type initializer for 'System.Xml.Schema.XmlSchemaComplexType' threw an exception.;Bad IL range.."

Any ideas?

Thanks in advance

 

 


ASP.NET Best Practices for High Performance Applications

  
This article lists the techniques that you can use to maximize the performance of your ASP.NET applications. It provides common issues, design guidelines, and coding tips to build optimal and robust solutions.

High-Performance .NET Application Development & Architecture

  
It has always been a goal of project architects to plan an effective strategy from the ground up in regards to an new application. All relevant factors are taken into consideration with respect to the application, from its design and layout to a functional website infrastructure. Pre-.NET strategies and design guidelines still effective now were developed with Microsoft's DNA (Distributed interNet Application) platform. This model successfully served the purpose of architecting N(any number of)-Tier (levels) applications. In its basic sense, as in most robust, distributed applications, you'll architect 3 main layers or Tiers: presentation, business rules and data access.

High Performance ASP.NET - Speeding Up ASP.NET Pages

  
have been writing a series of blog posts, which I have named High Performance ASP.NET Websites Made Easy! There is no rhyme or reason to the order of these posts and certainly can be read in any order:

10 Tips for Writing High-Performance Web Applications

  
Writing a Web application with ASP.NET is unbelievably easy. So easy, many developers don't take the time to structure their applications for great performance. In this article, I'm going to present 10 tips for writing high-performance Web apps. I'm not limiting my comments to ASP.NET applications because they are just one subset of Web applications. This article won't be the definitive guide for performance-tuning Web applications-an entire book could easily be devoted to that. Instead, think of this as a good place to start.

Built-in Functions - Text and Image Functions in SQL Server

  
Text and image functions operate on TEXT, NTEXT and IMAGE data types. These data types are deprecated with SQL Server 2005 and should be replaced by VARCHAR(MAX), NVARCHAR(MAX) and VARBINARY(MAX) when possible. Alternatively you can also consider storing large string values using XML data type. Text and image functions are nondeterministic.

Future versions of SQL Server will not support TEXT, NTEXT and IMAGE data types. Columns with TEXT / NTEXT data type do not support commonly used string functions such as LEN, LEFT, RIGHT, etc. Furthermore, due to the large size of TEXT data you''re likely to see performance issues if you store such data in the database. However, at times you can''t help but use the TEXT / NTEXT / IMAGE data types (for example when supporting 3rd party databases when you cannot change the schema) - this is when text and image functions come in handy.

Program for Format Conversion of An Image

  
.NET provides extensive support for image conversion. Any image can be processed from one format to another. Most common formats to which .NET have support for are .BMP, .EMF, .GIF, .ICO, .JPG, .PNG, .TIF and .WMF.

Configuring Profile Image Export in SharePoint 2010

  
It's no secret that I am thrilled with the new social features of SharePoint 2010. I am most excited about the new Profile Picture handling. I strongly believe that the more we can show the faces of our colleagues to one another the more connected we will feel. Clearly Microsoft feels that way as witnessed by the many features that make use of the Profile Image like the Activity Feed and Colleagues list

ASP.Net Upload Image to MS Access Database

  
As you learnt from the previous articles to upload image to the SQL Database in ASP.Net 2.0 and stream that image into the memory to retrieve it from the database and display it on the web page. In this article you will learn how to upload images to the MS Access database in ASP.Net 2.0

First of all create an Access Database and place it in the App_Data folder of ASP.Net web site project. Then create a table "tblImg" with the following fields:
