比较2个tiff文件&创建结果文件 [英] Compare 2 tiff files & create result file

问题描述

我想比较两个tiff文件&结果应该在另一个tif文件中。假设我正在比较a.tiff和b.tiff。必须用不同颜色的c.tiff捕获所有差异。如果给定的tiff文件中的像素相同，那么它必须是一种颜色。如果添加/删除，则它应该是不同的颜色。你能帮我拿到源代码吗？我计划在windows / c ++ / vs2010中构建这个



我尝试过：



我是这类工作的新手。

Hi,
I want to compare two tiff files & result should be in another tif files.Assume that i am comparing a.tiff and b.tiff . all the difference must be captured in c.tiff with different color. If pixels are same in both the given tiff files then it must be in one color. If added/removed then it should be in different color. Could you please help me to get source code. I am planning to build this in windows/c++/vs2010

What I have tried:

I am new to this kind of work.

推荐答案

因为你使用的是Visual Studio我建议使用图像类 [ ^ ]。



用 CImage ::加载两张图片加载 [ ^ ]和迭代像素（ CImage :: GetWidth [ ^ ]， CImage :: GetHeight [ ^ ]）。根据每个像素的结果（ CImage :: GetPixel [ ^ ]）设置所需的像素值（CImage :: SetPixel [ ^ ]）在其中一个图像上完成后用输出文件名保存（ CImage :: Save [ ^ ]）。如果您不想为输出重复使用一个输入图像，请创建第三个 CImage ，并填充和保存相同的大小和颜色深度（ CImage :: Create [ ^ ]）。



以上 CImage :: Save 链接没有提到TIFF格式，但它应该可以使用 Gdiplus :: ImageFormatTIFF 。

Because you are using Visual Studio I suggest to use the CImage Class[^].

Load the two images with CImage::Load[^] and iterate over the pixels (CImage::GetWidth[^], CImage::GetHeight[^]). According to the result of each pixel (CImage::GetPixel[^]) set the desired pixel value (CImage::SetPixel[^]) on one of the images and save that with the output file name when finished (CImage::Save[^]). If you don't want to re-use one input image for the output, create a third CImage with the same size and colour depth to be populated and saved (CImage::Create[^]).

The above CImage::Save link does not mention the TIFF format but it should work using Gdiplus::ImageFormatTIFF.

注意你的陈述非常模糊和数十种算法可以匹配描述而不会有用。

Note that your statement is very vague and tens of algorithm can match description without being useful.
