Hello,
Re: image processing
What you want to do, particularly the "combine two images from different angles" is usually called Image Stitching, and there are some standart methods of doing this One of the must-know-about API's for this kind of image manipulation is OpenCV, which is in C/C++. I used it myself last year to do precisely Image Stitching There is a project on github that wraps it to a ruby gem. The fork with the most recent updates (about 10 days ago) is this one https://github.com/ruby-opencv/ruby-opencv However, i've never used it (just learning about it by searching about your question), so i can't tell if it's any good. But in case it's not usable for your project, you can always code the image processing code in C/C++, and integrate that in your final ruby app On Fri, Sep 28, 2012 at 3:31 PM, andrew mcelroy <sophrinix@gmail.com> wrote: > > > On Fri, Sep 28, 2012 at 9:25 AM, andrew mcelroy <sophrinix@gmail.com>wrote: > >> >> >> On Mon, Sep 24, 2012 at 8:40 PM, Nicol嘆 L. <lists@ruby-forum.com> wrote: >> >>> I'm trying to build a program meant to recognize plants by looking at a >>> picture of their leafs or similar parts. >>> >> >> I'm doing this kind of detection with animals. >> There is a ruby opencv library, but it doesn't have 100% api coverage and >> opencv can be a beast in its own right to install. >> >> >>> >>> The approach that I had thought to would be: >>> - create a mathematical model of the leaves to be recognized >>> - maybe use some algorithm to combine two pictures from different angles >>> into one with depth measurement (absolutely don't know how this is done) >>> - confront the elements of the picture using distance or colors with the >>> models in the database (basically using only the shape of the borders) >>> >> >> Stone Age.
