I have 3 images. All of them have a different background color and each have a different font used but have the same "number".Basically, I have 3 images, one with black background and another with red one. One image haver the number one "1" write in Arial and another with the same number but in comic sans and a third with number two "2"There's anyway to VB tell that are the same number inside?Maybe if I compare pixel to pixel and choose the one with less difference in pixels will do it?
View 1 RepliesI 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.
Ok so I'm making a slot program where I have 3 picture boxes displaying a possible 9 images:
Bar

The error I get is saying that = is not the correct operator even though it worked for my case statement
im creating a program which detects motion according to how much difference does the two images have. take note images come from a live webcam stream. the problem is how to compare the two images.
description of the program
a sensitivity text box will be placed on the program where it will compare with the computed difference of the two images. i have a program in vb6.0 that compares images like this
Private Sub Timer1_Timer()
'getting picture from camera
SendMessage mCapHwnd, GET_FRAME, 0, 0[code].....
now i cant translate this in vb.net i have included what i have now
I have two textbox in my application.
Textbox1.Text="19-Jan-2010"

they need to make some compare version between host version and client version.. and each 1 version different will download the file to the client..[URL]..with both example, how can i make a program in VB.NET just like i said just now?
View 15 RepliesThe idea is to scan a folder of images and then let the user navigate back and forth through the images using a couple of buttons.The problem is, I can only get it to return a single image, and not the whole lot. It's looks to me as though the images are getting assigned to the same index in the array. [code]

View 3 RepliesThe app i am working on is for creating theme for the iPod touch... It has to deal with LOTS of images (100's potentially) There will be the set of default images, and then the user created replacement images. I started loading all the defaults into a resx file... thinking then I could just pull them out. now that I started setting the default, this sucks! lol the app will do this, on load it will set all the images (variables) to the resx images then when a theme is loaded, it will replace the default with the user image (if the user img exists) otherwise, the default stays. Then the "screen" is drawn to show the user. so, here is just the images to build the wallpaper, dock, and status bar...

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?
View 2 RepliesI 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.

View 1 RepliesI have placed several PictureBox Images of different colored dots(which represent lights) on an image of a Christmas Tree. I can make the lights randomly flash using a randomGenerator and a Select case statement. However, the code is very long. There are 67 lights on this tree and the code is 71 pages long. There has to be an easier way to do this. So far I have tried the following with two images of lights just to see if it would work and it does not work:
Dim picLight(2) As
Boolean
For intX

I've been coding using vb.net for a while but I've been using imageLocation property to set an image for a picturebox or for the background image of a form. How do I use those images in my Resources Folder in my solution explorer to set an image for a certain picturebox or form. I sorta need a code for it.
View 7 RepliesI'm creating a form which is basically an image in a picture box that I use the graphics object to do drawstring's and drawimage's upon.I keep track of where I'm drawing these things so that I can click on them later and do various things (launch external apps - whatever).Is using a picturebox and the graphics object the best way to approach this.

Okay what i what to do is to compare one picture to another continuously untill it finds a change and then launches my code. Picture 1 - A picture i put to the form Picture 2 - I wont this to take a picture in a certain area and compare it to the first picture. lets say the first screen shot it took didn't match 'Picture 1' then it will keep taking pictures until it finds something different and when it finds something different it will launch my code.
I dont know if this is the right way to go since i heard something about pixel scanning but that's to hard since you have to find the exact RGB of that pixel. Also theirs like billions on the screen so it would be hard to find a change of color on the screen and then launch a code after that and keep repeating.
I am working on my program as I have created picturebox1 and splitter1 in my program. I am coding on the if statement as I am trying to compare on the value that if they are less than 184, then do something.
Private Sub PictureBox1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles PictureBox1.Click
If Splitter1.Location <= New System.Drawing.Point(184, 0) Then
[Code]....
I know that I can't compare the value using with <= which I will only have to use = instead of <=, but i still want to compare with the value that if it less than 184, then do something.
