So I'm designing a few programs for editing photos in python using PIL and one of them was converting an image to greyscale (I'm avoiding the use of any functions from PIL). The algorithm I've emp...

Here's what I would like to do: I'm taking pictures with a webcam at regular intervals. Sort of like a time lapse thing. However, if nothing has really changed, that is, the picture pretty much lo...

I'm a beginner. I tried Image Classification by Tensorflow, and got the following error. I found the similar issue on web, but I couldn't understand. What does the error mean? How should I do for i...

I am running a python code to check similarity of Quora and Twitter users profiles photos, but i am not getting a positive result when images are the same. This is the code for comparing the two i...

I am working on a project in which the two images will be checked for similarity like 'Google Image Search by image'. I searched through Google and also on various sites including stackoverflow an...

I am looking for a way to compare two images to see how similar they are. Googling it produces tons of image processing results (cropping, re-sizing, etc.), but nothing that would do approximate co...

I'm building this for iOS using Swift — either via CoreImage or GPUImage, but if I can build it in Python or Node/JavaScript, that'd work too. Feel free to answer abstractly, or in a different lang...

I am currently working in Selenium WebDriver to compare two images during automation. Currently I am using pixel comparison but the problem comes if the browser size is changed or the system is dif...

*Note: while this post is pretty much asking about bilinear interpolation I kept the title more general and included extra information in case someone has any ideas on how I can possibly do this be...

I need an algorithm that can determine whether two images are 'similar' and recognizes similar patterns of color, brightness, shape etc.. I might need some pointers as to what parameters the human ...

I have a large number of images (hundreds of thousands) and, for each one, I need to say whether or not it has a watermark in the top right corner. The watermark is always the same and is in the sa...

I am doing vlfeat in Matlab and I am following this question here. These below are my simple testing images: Left Image: Right Image: I did a simple test with 2 simple images here (the ...

i want to compare two images like image1.png and image2.png.both the images look pretty same with some difference. so i want to get the difference and want to apply the difference on first image im...

I want to find/check subImage/template image in main image and want to know its coordinates, I have used code given at following link to implement it, Check presence of subimage in image in iOS ...

I have 2 images, say smallerImage and largerImage. Now, I want to check that does smallerImage is part(or subimage) of largerImage or not. I am not getting how to check that. I want to so thi...

I have used the SIFT implementation of Andrea Vedaldi, to calculate the sift descriptors of two similar images (the second image is actually a zoomed in picture of the same object from a different ...

I currently have a single AsyncTask which currently compares images using the bubble sort technique using OpenCV. Say, I have to compare 400 images to each other. This would mean 400*401/2=80,200 c...

[EDIT] I have devised some code for image comparison. The matching part is still a bit flawed and I would love some assitance. The project can be found at - GitHub. I have these two images Img1 an...

Is there a quick and easy way to do such comparison? I've found few image compare questions from stackoverflow but none of those actually proved answer for this question. I have images files in m...

I recently stumbled upon a SIFT implementation for C#. I thought it would be great fun to play around with it, so that's what I did. The implementation generates a set of "interest points" for any...

I am new to OpenCV. I would like to know if we can compare two images (one of the images made by photoshop i.e source image and the otherone will be taken from the camera) and find if they are same...

Is there any basic (free or not), but usable - not like libpuzzle - image fingerprinting/similarity/compare module for PHP, which works akin to TinEye or Google image upload search? It's basically ...

Several questions have been asked about the SIFT algorithm, but they all seem focussed on a simple comparison between two images. Instead of determining how similar two images are, would it be prac...

I have made a videochat, but as usual, a lot of men like to ehm, abuse the service (I leave it up to you to figure the nature of such abuse), which is not something I endorse in any way, nor do mos...
