如何根据另一幅图像的像素绘制一幅图像？
大家好，我想要的是映射图像。假设我有两张人的图像，一张是胖子，另一张是弱者，现在我想匹配他们的脸，眼睛。我想增加或减少脸部一张图像的眼睛大小根据另一张图像的大小。正如你在 adobe Photoshop 中看到的那样，你可以使脸部变胖，使其挤压。我想在其中进行图像处理。我想实现这些类型的操作。我不'不知道从哪里来开始。 请指导和帮助我。我可以使用核心显卡执行所有这些操作吗？如果是的话，那么如何执行 任何参考、教程地址、示例代码......不胜感激。

如果要自动完成的话，您可能至少需要处理某种边缘检测和面部识别算法。否则，如果用户要调整一个图像的大小以匹配另一图像，则这将需要由用户捏合和捏合驱动的简单调整大小操作。手势。

要手动调整大小：
下载这本好书的源代码很酷的 iPhone 项目。其中一个项目名为“Touching”。该项目包含完成您所需的代码：捏合和缩放功能。
You are probably going to have to deal with some sort of edge detection and face recognition algorithms, at the very least, if this is to be accomplished automatically. Otherwise, if the user is going to be resizing one image to match the other, this will require simple resizing operations driven by perhaps user pinch & gestures.
UPDATE:
For manual resizing:
Download the source code for the great book Cool iPhone Projects. One of the projects is called 'Touching'. This project contains code that accomplishes what you need: pinch and zoom functionality.
