I have taken a picture of a very old image . That picture is itself a bit scarred and so the content of the image is not properly visible. Is there any image re construction or extrapolation software available which I can download and use it to re construct the image and make it very clear to the naked eye ?
I would suggest using photoshop but if you want to use other tools that are maybe easier (more friendly) than akvis.
I honestly would go the route of photoshop and go through photo restoring tutorials (tons online).
Good luck

So I have a programming project that I have to do for my school. What I have to do is setup a 2 player dice game. I could have gone the easy way and just display the number of the 2 die, but I was thinking of using images that I made in photoshop instead. However, the problem is that I do not know how to change images in an efficient way.
My first option is using the visibility tag on several images laid on top of eachother and change it accordingly as such
image1.visible = false
image2.visible = true
However, I do not think that is very efficient. Images also do not support changing the image with code from my research.
Secondly, I could use a PictureBox instead, which do support changing the image as the program is running. However, it does not support transparency, and the die images are transparent. Plus it gives me the invalid image file error, I guess due to the transparency in the gif files.
There is also the cheap workaround of me making the background of the images the same as the form background.
So is there a more efficient way I am missing out? I know that the cheap workaround would be the best option for this case, but I would like to have this knowledge for future use like semi-transparent pixels that blend in and such.
And before you ask, no, I cannot use another programming language as visual basic 6 is what my school teaches. Thankfully they are changing it soon, but I am stuck with this for now.
Turns out you CAN change the pictures of Images, while keeping transparency and stretch. I am going to properly show it:
Image1.Picture = LoadPicture("YOURPATHHERE.gif")
This is what I get for believing what I've seen on some forum.
Also, the error of invalid image file was due to the images being corrupted for some reason.
So, I don't believe that exists someway to "read" a PNG through its binary code, or something like that, but I have zero knowledge on Image Processing or Computer Vision, and so, I can't be sure if that are ways to do it or not.
To be clear: I want to know if there are ways to identify the image of a Logo using an image of the Logo as reference but through methods that use only the binary of the image.
Thanks in advance
If the logo is known, and not distorted a lot (logo printed on a scarf is not as good as on a flat surface), there is technologies that can achieve that:
It is a template matching problem, see https://docs.opencv.org/4.5.2/d4/dc6/tutorial_py_template_matching.html.
Is there a way to display so many images ? Maybe something like google maps, that would show all images at once as tiles and you could zoom in and see the picture in detail... ?
This problem can be easily solved by merging all images side by side like a collage.
This task can be automated by using python using its pyautogui module and any simple software for image manipulation.
By doing this a single image of very high resolution can be obtained achieving your purpose.
(Although the size of the image would be mind blowing.)
See these sites for similar works (1.2 Billion images) but with smarter solution (the are loading few images at a time upon zooming).

Ok, it took very long time to process and finish, but I made it ! It CAN be done. correct tools are libvips and its python version pyvips I managed to get all 366 000+ pictures in one, and then made zoomable pyramid dzi with it ! To display it OpenSeadragon since the final picture was 81GB and nothing can open that.... http://deepzoom.reverz.sk/ ( also not sure why my question was down voted :-/ )
i have problems to obtain good thumb from some images, when the original images are striped or checked shirt.
With the magento's gd2 library resize() in Varien_Image_Adapter_Gd2 class (magento 1.5 version) i obtain an image with a strange effect that modify the aspect of real image.
I can't find the name of this effect, so i can't search this issue on google! :(
You can see my issue in these 2 images:
As you can see, on the thumb image there are some rolling strange lines in particular in top-left position.
The issue is more evident on checked shirt, so i have to find a solution to correct this.
If anyone have some tips on this issue, please said me! :)
thx

'Moire' is the pattern you describe and it is particularly visible due to use of 'gd2' library which may or may not use bicubic scaling.
I am not sure that #Guerra has understood the problem here, but, to me, it is a straightforward lack of bicubic (or better) scaling.
See the answer on this question and follow the link:
https://stackoverflow.com/a/255666/1617149
So you may want to scale your images for the frontend using imagemagick instead of the standard gd2 library that comes with Magento and use a filter.
You can run imagemagick through php (the proper way), or, if you have complicated image processing on the go, you can go commandline 'exec' and prototype your image processing that way. I don't have any ready-to-roll code for that, however, that is what you need: better thumbnail rendering than you get with gd2.
Try use cloudzoom, he autosize your images to fit on your needs.

Hello I am building a social network similar to facebook and I really need some help on how to handle the images in my website. I would like to know how sites like facebook manage the resizing of their images. An example would be looking at someones photo album. The length and width are not just simply changed. They are done in a more professional way to make the image still look clear and not stretched. Do they use a special tool for this. Another example would be profile pics when they are loaded to your message wall. Your friends profile pics are centered and cropped accordingly and then re sized. How do they go about doing this. Any help would be greatly appreciated.
They resize proportionally with an imaging library like GD, Imagick or others.
The presentation in the gray area is just that, presentation so HTML and CSS.
They stretch the images proportionally so that they don't look wrong; if you make the image 37.5% wider... you also make it 37.5% taller.
If we knew what language you are familiar with, we could probably suggest something to help with this.
