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.

The 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]

[2008] TONS - Set Of Default Images And Then The User Created Replacement Images

Feb 11, 2009

The 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...

VS 2010 :: Make An Application To Save Images [or Download Images] To Local Hard Disk

Aug 12, 2010

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?

Make Several PictureBox Images Randomly Visible = False And Then Back To Visible = True Giving The Appearance Of Flashing Or Blinking Images?

Jun 28, 2010

I 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
