我的图像，从一现场摄像头拍摄，我希望能够检测图像中的特定对象，并提取该部分的它做一些进一步的处理。

I have an image, taken from a live webcam, and I want to be able to detect a specific object in the image and extract that portion of it to do some further processing.

具体而言，图像将是一个游戏板，我们先来说说这个问题，这是一个数独游戏板的目的。这里是一个样本图片。

Specifically, the image would be of a game board, let's say for the purposes of this question that it's a Sudoku game board. Here is a sample image.

我最初的做法是寻找对比的地区，从那里工作了，但我似乎结束了很多潜在的边缘（许多错误），并没有真正的线索，如何制定出哪些是那些其实我是想！

My initial approach was to look for contrasting areas and work it out from there, but I seem to end up with a lot of potential edges (many erroneous) and no real clue as to how to work out which ones are the ones I actually want!

是否有任何的算法，图书馆，code样品，甚至只是高见在那里，至于我怎么会去寻找和提取图像的相关部分？

Are there any algorithms, libraries, code samples, or even just bright ideas out there, as to how I would go about finding and extracting the relevant part of the image?
