Hi,

you can use LabVIEW to do image recognition. Here is an example of the basic functions to do so. You can also search some examples with the Example Finder.

This little program looks for an image in a folder. He analyses each picture, and makes a comparision between the searched picture and the pictures in the folder.

I hope it will help

can you please give me some more details.searched image is the image that we want to search i.e to check whether it is in the folder.when we give  path of the image ,it will create a path for that image in the vi's folder,then the program will check the folder where that vi file is stored and compare all the images with the given searched image and it will display true if it matches and gives the file path of that image file.am i right?even if the image does not match it will displey the searched image and 24 bit pixel array?please can you help me with my doubts.

and thanks for your reply

hi,

yes exactly. The boolean in the array will be true if 2 pictures match, , and false if not. The path of every picture will be in the array, even if they don't match with the searched picture 

The 24bit array is just for the searched picture. 

I tried to show you some basic functions of how to do a picture recognition. You will have to adapt your program with those functions. This example is just... an example. The only thing you should keep is the case structure. Because a png or jpeg has different set of functions, this case is necessary (ie take the extension of the file, and choose the good function).

i hope i have been clear enough
