iOS CoreImage边缘检测 [英] iOS CoreImage Edge detection

问题描述

我正在编写iOS，我需要能够在图像中进行边缘检测。我实际上想要类似Photoshop的痕迹轮廓。因为我基本上需要使用最简单的线条来处理..事情是我似乎无法弄清楚如何做到这一点，坦率地说我对OpenCV没有兴趣，因为我今天花了5个小时试图获得10个中的任何一个或者所以我下载的zips以任何形式或形式进行编译。
所以我希望也许有人可以用正确的方式指出我使用内置于os的内容......或者可能是一个例子

I am writing an iOS as and I need to be able to do edge detection in the image. I actually want something similar to Photoshop's trace contour. Since I basically need to get the simplest set of lines to work with.. Thing is I cannot seem to figure out how to do it and frankly I have 0 interest in OpenCV since I spent 5 hours today trying to get any of the 10 or so zips of it I downloaded to compile, in any way shape or form. So I was hoping maybe some one could point me the right way to do it with what's built in to the os.. or maybe an example

推荐答案

如果我自己没有使用它，但你是否正在寻找像此？它基本上是一个C ++包装器，它声明了一个名为 ImageWrapper * cannyEdgeExtract（float tlow，float大腿）的方法。

If haven't used it myself, but are you looking for something like this? It's basically a C++ wrapper and it declares a method called ImageWrapper *cannyEdgeExtract(float tlow, float thigh).
