如何在Matlab中附加图片? [英] How to Append pictures in Matlab?
问题描述
我想在没有imagemagick的系统中做这个伪代码但我在系统中有Matlab 2016a和Java
I want to do this pseudocode in a system without imagemagick but I have Matlab 2016a and Java in the system
convert 1.png 2.png +append result.png
假设你想在如下的循环中连接这样尺寸可能不匹配。
但是,所有对象1,2,...,N具有完全相同的尺寸。
但是,以下循环会同时连接两张图片,使尺寸与后续图像不同:bigImage vs new image。
Assume you want to concatenate in a loop like the following such that dimensions may not match. However, all objects 1,2,...,N have exactly the same dimensions. The following loop, however, concatenates two pictures at the same time, making the dimensions different with subsequent images: bigImage vs new image.
iterationCounter=1;
result=0;
while(iterationCounter < 3)
imgRGB=imread(filenamePng); % Images 1,2, ..., N have same dimensions.
if (result==0)
result=imgRGB;
end
% http://stackoverflow.com/a/35915990/54964
if (ismatrix(result(:,:,1)))
heightRatio=size(result,1)/size(imgRGB,1);
wantedSize=int16([size(result,1), size(imgRGB,2)*heightRatio]);
imgResized=imresize(imgRGB, wantedSize);
result=[result, imgResized];
end
iterationCounter=iterationCounter+1;
end
其中输出为空图片。
如何在Matlab / Java中水平追加图像?
How can you do the horizontal appending of the images in Matlab/Java?
推荐答案
这应该有效:
imwrite([imread('1.png') imread('2.png')], '12.png');
注意:它们应具有相同的宽度/高度,具体取决于您添加它们的方式。
