Develop A Image Processsing Application That Will Analyse Some Grayscale Images?
Jan 14, 2012
I am trying to develop a image processsing application that will analyse some grayscale images, the images in question are basically biological photographs(PCR GEL Photographs) that have some bands which are lighter in shades, and these bands are arranged in some pattern( Mostly linear), Till now, i had suceeded to programatically identify those bands which are distinct and clearly seperated from other band, but the band, which are close, could not be identified as seperate band.more over my algorithms fails miserably in case case of color photographs,and i am clueless for a better approach.
My plan is this: 1. input the picture to a picture box no 1 2. load into memory 3. extract all value to a 2D array matriks 4. process the picture 5. Show the result in picture box no 2 6. End
I met a serious problem when i want to load it to memory. For a faster process i use Graphics class (i've got this trick from my friend). but later I found out that graphics wont work for PixelFormat.Format8bppIndexed.
Here's the code:
Imports System.Drawing.Imaging Imports System.Runtime.InteropServices.Marshal Public Class LockImage
I'm creating a Image viewer and was wondering if anyone could help me with resizing an image, and converting the image to grayscale? My knowledge of visual basics is very limited so any code snippets.I am wanting to resize the original image to a 3 x 3.
Any code for creating the pallet for a Gray scale image, to display it on a picture box? I have written the code for creating for palette for a RGB image which is as follows:
Marshal.Copy(Image_bufffer, 0, _pImg, 1024 * 1024) myBMP = New Bitmap(1024, 1024, 1024, System.Drawing.Imaging.PixelFormat.Format8bppIndexed, _pImg) pal = myBMP.Palette For i As Integer = 0 To pal.Entries.Length - 1 pal.Entries(i) = Color.FromArgb(255, i, i, i) Next myBMP.Palette = pal Picturebox1.Image = myBMP 'Show the image
But the image displayed looks dull(less brightness) than the same image viewed from ImageJ. So instead of creating pallet from color.Argb, is there any way to create palette for a gray scale image?
I am developing a visual basic 2008 express edtion program of an organisation that should get images from the system and display on image/picture box. further the program should save the displayed image in access database so that it can be retrieved together when you want to search the information about that particular employee.
I was thinking to make an app to save images [or download images] to local hard disk. But to keep it easy, I want this app to create a small picturebox on form to show the thumbnail of downloaded image. Lets say a 5 pictureboxes has to be added with the thumbnails to show the recent downloads. A user can save the location where he wants to save the files on hard disk. A listbox or a dropdown menu will help in categorizing the images, like image1 in friends section, image2 in family section, image3 in others, etc... When the program restarts all the latest 5 thumbnails has to be loaded in pictureboxes and the directory that was chosen. Finally, a button that shows the downloaded images into original image file size one by one or a slide show. Is it possible to make such program?
I have got two image folders namely a and b which consist of images of products. All images are save as there productid. how can can i find the images from a folder by passing there productid and save the images in a list.Dim AllImages As New List(Of String)
After saving it , how can i render those images one by one into string builder like
Dim imagecontainer As New StringBuilder For Each image In AllImages imagecontainer.Append("<img src="image" alt="" />") Next image
I am new to this forum and I would like some help from my respected seniors.I am trying to develop a ASP.Net Web Application using C# or VB. First of all prefer me whether C# would be easy or VB for the following scenario:Below are the requirements:
1. For All Users:
Text-chat feature will allow users to chat with the available online users.
2. For Registered User:Allow users to create new folders and sub-folders, to store (upload) files.Allow users to perform move/copy/delete operations on folders and files. The percentage of storage capacity remaining and used should be displayed on the top. Automatic versioning system will record the version/revision information when a file is replaced/overwritten Team management feature will allow users to work in teams (by inviting other existing registered users). The activities of the team include access to the password protected area for the team, uploading files, commenting on the uploaded files (discussion), polls, automatic and manual reminders to the team members.
3. For Administrator:
Approve/Reject new team requests; update/delete existing teams.View all the files and folders uploaded on the server.Allow to perform delete operation on any existing file/folder existing on the server.Delete account for any registered user.Define and Edit storage capacity and other limits such as Maximum file size allowed for uploading.
Queries:
1) As, every user will have his/her own PERSONAL profile page then how will the system redirect the user to his/her PERSONAL profile page after hitting Login?
2) How this chatting feature can be developed?
3) How this storage capacity would be assigned overall?
4) How Administrator will manage all this?
I am totally confused.I have developed SRS as well. but in coding I am totally stuck as I am not so good in coding. I thought Visual Studio 2010 would help me effectively in this case, and I am trying but couldn't find any way for this to be done.
where I have to try organise a number of databases. Some of these I am sure are duplicate databases.I was wondering if anyone knew if there was a way to interigate the database objects so as to make a comparison between databases (see if they are in fact duplicates.)I would (ideally) like to get a list of all database objects - such as queries, forms, tables,modules etc.. Then look at either the "date modified" or "date created" property so as to see which is the most up to date as well as somparing the contents of the database.I have played with Delphi and dbGo to try see if I can get the info required - but cant seem to get all the properties I need.Here is an example of what I have tried using the "openschema" method such as...
I want to develop an accounting software for a mini Super-Store, this program will be able to run on a network with a central database; in other words a network application. I have not used sql sever before neither have I written any application that will run on a network.
I am very keen to build a simple application to convert AVI to jpg in order to learm a little about video processing. I know free applications that do this already exist. But, I'd still like to develop an application to help me learn more about avi's and to hone my programming skills a bit with a real project.I'm familiar with VB, so that's not a problem. I just don't know how to process an avi file nor how I would programmatically extract the frames from that file.Where should I start? What is required to extract frames out of the avi to individual jpgs?
I am looking to write some VB.Net console applications. However, I do not have Visual Studio yet at work, and it probably will be a while before I do. Is there anyway to develop my application, compile, and run it without Visual Studio?

I'm going to do my graduate dissertation this year .My title is develop a forensic tools which is able to detect and analyse the file signature then compare it with the extension.If the extension is wrong match with the file signature then there is a feature in the tools that would revert the wrong file extension to its original state.The problem is there is little information could be found online that shows the code library or function that could enable me to program the above mentioned feature.Could it be implemented on the vb.net or i should do it on C#?Any sample code that could peform the file signature with the extension and also correct the file extension according to the signature in vb?

I would like to develop an application that involves a lot of tables and maths, and then displaying the results. I can visualize how this would work in SQL, as far as creating the stored procedures and tables required, however the front facing application would be a completely new experience to me.I would probably be sharing the built application with friends, but completely as a no profit tool. I assume that the developer edition of dot net is a suitable option? My main query is, is dot net really the best way to develop this tool? I have a strong feeling that I will not be able to use SQL as this would require a server to be run, and this is not practical. Can the tables be implemented into a DLL or similar to be used by the application for example?
I want to develop an app which won't allow the user to open or jump to another application while it is open. It should be in Visual Basic. For example, if my application is open (running) and the user tries to open any other windows application like "media player" then it shouldn't open. The app should not even allow "task manager" to run. The application should completely block the windows environment while it is running.
I need a little guidance here. What I am needing to do is develop an application which sorts text files, approximately 10 at a time.It would look something like this. (Using VBA 2008)The code I am having trouble with, is I want to be able to "load" 10 of these txt reports.I want the Sort button to trigger the application to run through each text file looking for specific keywords.
And finally, when all is said and done, I want it to export a new text file with the keywords listed that it found.I am just breaking into this and am super excited with how much I have learned so far!

About 5 years ago I wrote this program in Excellusing VBA to compute commissions, income and expenses for the real estate agents in my wife's business.The company is made up of about 50 agents. Part of the program includes a combobox on a main form when a name was selected it also selected, the agent id, and the split the agent was on. It would calculate the split expense that my wife got by multiplying the split percentage from the combobox times the total commission.The main form also contained various other comboboxes, list boxes, and text boxes to gather such info as property address, selling price, titles company, transaction credit,income,Once all the info was complete my wife was asked if she wanted to save the transaction. If the answer was yes, the info was transferred to the permanate database, a commision report for the agent and my wife was printed out, and the temporary database was cleared.
