Is there any api provided to find a image match/contains in a another image. Like opencv template matches ?

Steam images have url like this:
http://steamcommunity-a.akamaihd.net/economy/image/-9a81dlWLwJ2UUGcVs_nsVtzdOEdtWwKGZZLQHTxDZ7I56KU0Zwwo4NUX4oFJZEHLbXQ9QVcJY8gulRNRULFV_eS1M7DQEh4IEtDt7ekOQYu1aOQcGgSutizwIPYw6-mYe-AzzhQ68Mj2rmRpd-g3gXm80s9Zm_2cZjVLFH7KrlnRw/330x192
In the API can find these string:
-9a81dlWLwJ2UUGcVs_nsVtzdOEdtWwKGZZLQHTxDZ7I56KU0Zwwo4NUX4oFJZEHLbXQ9QVcJY8gulRNRULFV_eS1M7DQEh4IEtDt7ekOQYu1aOQcGgSutizwIPYw6-mYe-AzzhQ68Mj2rmRpd-g3gXm80s9Zm_2cZjVLFH7KrlnRw
Is there a way to decrypt it?
I believe that's off topic.
That's probably the image hash not the image itself.
You should then make a call to download said image the same way a browser to.
From the steam API docs:
img_icon_url, img_logo_url - these are the filenames of various images for the game. To construct the URL to the image, use this format: http://media.steampowered.com/steamcommunity/public/images/apps/{appid}/{hash}.jpg . For example, the TF2 logo is returned as "07385eb55b5ba974aebbe74d3c99626bda7920b8", which maps to the URL: [1]
I am developing an Android app now, it needs to recognize captcha from website.
I utilize the tess-two to recognize captcha and follow TrainingTesseract3 instructions to train my own traineddata (using jTessBoxEditor to correct characters), but it cannot recognize correctly and even cannot recognize it.
The below TIFF image is that I use to train my Tesseract, I collect many captchas and merge them into a image.
TIFF image
The image that I want to recognize
For example, the expected result of the above image should be k8666, but the actual result is only 66.
Does anyone give me a help? Thanks.
I tried your images using a .NET wrapper for tesseract-ocr Tesseract-ocr .Net Wrapper by Charliesw.
I got some better results like (K8EEE, K8656), i think you have to increase the text font and make it bold and i saved the image in tiff format with 96DPI resolution to get a better results than mine.
For example, given File:Wikipedia-logo-v2.svg as input, the output would include:
http://upload.wikimedia.org/wikipedia/en/thumb/8/80/Wikipedia-logo-v2.svg/200px-Wikipedia-logo-v2.svg.png
http://upload.wikimedia.org/wikipedia/en/thumb/8/80/Wikipedia-logo-v2.svg/500px-Wikipedia-logo-v2.svg.png

The original image is a vector, the urls you have provided link to the wikipedia thumbnail generator.
It will generate an image of any resolution you specify, you can just change the value in the url and it will generate an image of that size.
I don't know why you would want to use it however. You should just get the original image and scale it yourself to your own needs.
I am working on an application which will have an option for users to upload images. Once uploaded, the application will show other images from the web which look exactly similar, whether or not of the same size.
For this, I will create a temporary URL for the image so that I could provide Google custom search API the URL of the image. I would expect in response, URL's of images that are exactly the same or similar to it, perhaps in JSON format.
I did find a similar question posted in January. Till then Google did not support anything like this, apparently:
Google Javascript Custom Search API: Search images by image url
One can also simply do:
http://images.google.com/searchbyimage?site=search&image_url={Image URL}
Since that is not part of an official API, it may not be right to use this method.
Can someone help me?
Well, the answer quite simply is TinEye Commercial API https://api.tineye.com/welcome. I was looking in the wrong place I guess, I did not have any luck with Google Custom Search API.
Would you need a simple result?
If you are, you can use Vision API of Google.
This is very simple.
https://cloud.google.com/vision/
You can try on the top.
First, access the URL.
Second, upload your image file on the "Try API"
Third, click "JSON" tab menu on the result.
You can be seen JSON about similar images.
