I just checked the vi, it's just exactly what I was needin'. Well, with no cropping, but I can manage modifying that. Thanks a lot, guys! Well, I have license only for the LabView 2009, and no other modules included. Ask my superiors why they are so cheap . I don't like getting complicated either, but I have to manage only with what I have. I know what Imaq and Vision can do ... And anyway it's a good way to practice with LV

Thanks a lot, François! I will look into it. The problem is that where I am at this moment, I only have access to LV 8.5. I have to wait some time to gain a remote access to my home computer with LV 2009, and then I will check the vi you posted. I will give you a feedback after I'll check it. Thanks again!

Thanks a lot Vugie, I will look into it right away. I haven't heard of it before. Hope is works thanks again. Laurentiu

Hi there, Prasun Any luck with your SX 110IS camera? I have the same model, and I think I am also stuck with the same problems. Did you manage to do something about that? Thanks.

Hi Antoine, Thank you for your time. Attached you can see the code for loading the images. I load them from disk, so I don't acquire them from external hardware (cameras). It verifies if the extension of the file is either jpeg, png of bmp. I can send you the whole vi, but I think it looks pretty scary right now . I know how it looks what I'm trying to do. I already have the 2-D arrays of the images and decoded the RGB palete into separate colour codes. As for ROI, I was thinking of a sort of overlay or mask over the picture tool, and then use some mouse events or drawing a rectangle on a transparent layer, and then taking the coordinates of the drawn rectangle and use them as the coordinates of the "selected" are in the original picture. I know it may sound stupid maybe, but as I told you, I don't have access to the specialised modules . Only the cracked versions, but of course those won't help me further .

Hello, I am new around here. I've been working with Labview for a while. I am working on a project that involves image processing (actually some stereo image matching algorithms, that is). Since the algorithms that I've tried to embedd are way too slow for big images, I want to implement a ROI tool that allows me to select a rectangular area in one image, and apply the algorithm only on that area of the images. The problem is that I don't want to use IMAQ and Vision. I don't have access to them, so I just want to use the default functions of Labview. Any help here, would be greatly appreciated. I am sumbled upon this problem, cuz I don't know how should I do this ... Another question would be on the slow speed image loading in labview. For an image of 2000x2000 pixels, per se, it takes some time to load it. Is it normal? Thank you, Laurentiu A. Romania.

Hello! I am new to this forum. But I have a problem that seems I cannot resolve the way I want. I also want to create a R.O.I. method, but without VISION and IMAQ modules. I am working on an image processing project, in which I want to use only the default functions (Full Development) in LabView (either 8.5 or 2009). The only things I can find on the internet is only ROI with VISION. Can you give me some hints on this? Thanks a lot. Laurentiu A.
