Question

OpenCV Java Preset中的图像是否有permute的等价物？我的图像表示为org.bytedeco.javacpp.Mat。我正在使用下面的JavaCpp OpenCV预设

<dependency>
    <groupId>org.bytedeco.javacpp-presets</groupId>
    <artifactId>opencv</artifactId>
    <version>3.0.0-1.1</version>
</dependency>

更新，在评论中的@Miki建议之后，尝试使用mixChannel api。但它似乎没有与置换相同的功能代码：

Mat responseMat = new Mat(imageViaNetwork.toByteArray());
Mat image =  imdecode(responseMat, -1);
Mat resizedImage = new Mat(image);
resize(image, resizedImage,new opencv_core.Size(height, width),0,0,  opencv_imgproc.INTER_LINEAR);
Mat transposedResizedImage = new Mat(resizedImage);
int from_to[] = { 0,2, 1,0, 2,1 };
org.bytedeco.javacpp.opencv_core.mixChannels(resizedImage, 1,  transposedResizedImage, 1, from_to, 3 );

输出：

resizedImage：org.bytedeco.javacpp.opencv_core $ Mat [width = 300，height = 200，depth = 8，channels = 3]

transposedResizedImage： org.bytedeco.javacpp.opencv_core $垫[宽度= 300，高度= 200，深度= 8，信道= 3]

我希望transposedResizedImage的宽度/高度按照from_to数组中的顺序进行置换

JavaCpp相当于Matlab的Permute
