Hey guys. I got two images from video frames. They have a certain portion of overlap. After warping one of them, I'm currently trying to blend them together. In other words, I would like to stitch them together. But I don't know how to accomplish that. Can anybody please give me some help? Thank you!
Let's say the image data is store in 'image1_warped' and 'image2'. Appreciated your help!
The keyword here is Image Registration. The Image Processing Toolbox provides some functions for this purpose. The documentation has a some of demos as examples.
Checkout the blog post: Blend images with MATLAB,
with nice examples, and the MATLAB code.
Where the two images join apply the Photoshop clone tool (vary the percentage of opacity and size as required)

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.
I'm interested in converting a large vector graphic into an equitangular image. I'm looking to create an interactive 360 view in an AFrame project much like this one https://aframe.io/examples/showcase/sky/.
I've tried a plugin for photoshop called Flexify 2 but not having any luck. I'm open to different workflows or ideas on how to do this!
Any help would be greatly appreciated!
I need help with OpenCV to solve the following problem:
I have some pictures of one place
Each photo compare with the first
in the photos except the first I need to draw the frames where there was a change
Can anyone advise me or recommend a prime example?
That sounds like a job for background substraction.
BackgroundSubtractorMOG2 is the class you will probably want.
I have not used it myself, but here is a tutorial
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:

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.

I was wondering if anyone could suggest to me potential libraries in ruby for manipulating jpegs? Specifically I want to make the image 50% transparent so it can act as an overlay. The image in question would be of a house and I'd like it to overlay a village image.
Just being specific about the image as the transforms may not like multiple colours :)
Take a look at RMagick. This tutorial features transparency/opacity.
Best wishes,
Fabian
