I am currently working on a project and my goal is to locate text in an image. OCR'ing the text is not my intention as of yet. I want to basically obtain the bounds of text within an image. I am using the AForge.Net imaging component for manipulation. Any assistance in some sense or another? Update 2/5/09: I've since went along another ...
Hello! My task is pretty simply (well, it SOUNDS simple): given two different image file (in whatever format I choose), I need to write a program to predict the chance if one is the illegal copy of another. The author of the copy may do stuffs like rotating, make negative, or adding trivial details (as well as changing the dimension of ...
I would like to compare a screenshot of one application (could be a Web page) with a previously taken screenshot to determine whether the application is displaying itself correctly. I don't want an exact match comparison, because the aspect could be slightly different (in the case of a Web app, depending on the browser, some element coul...
I've recently come across a problem which requires at least a basic degree of image processing, can I do this in Python, and if so, with what? ...
How do you implement the fastest possible Gaussian blur algorithm ? I am going to implement it in Java, so GPU solutions are ruled out. My application planetGenesis is cross platform, so I dont want JNI. ...
I'm looking for some recommendations for solid computer vision & image processing fundamentals, including camera models, perspective projection, edge detection, corner detection, and the like. Edit: looking for reference books w/algorithms, etc - not libraries. ...
I am a little curious about the cute little kaleidoscopic images associated with each user on this site. How are those generated? Possibilities are: A list of images is already there in some folder and it is chosen randomly. The image is generated whenever a user registers. In any case, I am more interested in what kind of algorithm...
I need to put an alpha blended gradient border around an image. My problem is in blending the corners so they are smooth where the horizontal and vertical gradients meet. I believe there is a standard algorithm that solves this problem. I think I even encountered it in school many years ago. But I have been unsuccessful in finding any...
I'm seeking a library, technique or advice on how to read an EAN-13 barcode from an image (including ISBN,and ISSN encodings). The image would come from a mobile phone or webcam, so resolution may be quite poor and not well aligned. I'm specifically interested in something that could be used from ruby on rails, but answers for other lan...
I am looking into an image processing problem for semi-real time detection of certain scenarios. My goal is to have the live video arrive as Motion JPEG frames in my Java code somehow. I am familiar with the Java Media Framework and, sadly, I think we can consider that an effectively dead API. I am also familiar with Axis boxes and,...
Looking for one that is fast enough and still graceful with memory. The image is a 24bpp System.Drawing.Bitmap. ...
I need to implement red eye reduction for an application I am working on. Googling mostly provides links to commercial end-user products. Do you know a good red eye reduction algorithm, which could be used in a GPL application? ...
We are currently researching ways of enhancing image quality prior to submission to OCR. The OCR engine we are currently utilizing is the Scansoft API from Nuance (v15). We were researching the Lead Tools but have since decided to look elsewhere. The licensing costs associated with Lead Tools is just too great. To start with we are l...
I'd like to do some work with the nitty-gritties of computer imaging. I'm looking for a way to read single pixels of data, analyze them programatically, and change them. What is the best language to use for this (Python, c++, Java...)? What is the best fileformat? I don't want any super fancy software/APIs... I'm looking for the bare...
I'm looking for a free, preferably open source, http image processing server. I.e. I would send it a request like this: http://myimageserver/rotate?url=http%3A%2F%2Fstackoverflow.com%2FContent%2FImg%2Fstackoverflow-logo-250.png&angle=90 and it would return that image rotated. Features wanted: Server-side caching Several operatio...
My custom homebrew photography processing software, running on 64 bit Linux/GNU, writes out PNG and TIFF files. These are to be sent to a quality printing shop to be made into fine art. Working with interior designers - it's important to get the colors just right! The print shops usually have no trouble with TIFF and PNGs made fr...
For those not familiar with Core Image, here's a good description of it: http://developer.apple.com/macosx/coreimage.html Is there something equivalent to Apple's CoreImage/CoreVideo for Windows? I looked around and found the DirectX/Direct3D stuff, which has all the underlying pieces, but there doesn't appear to be any high level API t...
I am wondering if there is a way to combine multiple images into a single image using only JavaScript. Is this something that Canvas will be able to do. The effect can be done with positing, but can you combine them into a single image for download? Update Oct 1, 2008: Thanks for the advice, I was helping someone work on a js/css onl...
I would love find out which is the best image manipulation library for which platforms and languages. Likely you could use a library under multiple platforms with the right API or Plugin capabilities. I'm specifically looking for web based applications, but please answer for desktop apps as well if you like. Libraries (and the common di...
I'm looking for software to create PNG8 format transparent images as per this article. NOTE: I need a linux solution myself, but please submit answers for other OSes. ...
