依赖 bytedeco/javacv，开发时是1.3版本，如今1.5版本了。注意：新版本并不完全兼容老版本。
Java interface to OpenCV, FFmpeg, and more
<dependency>
<groupId>org.bytedeco</groupId>
<artifactId>javacv-platform</artifactId>
<version>1.5</version>
</dependency>
JavaCV uses wrappers from the JavaCPP Presets of commonly used libraries by researchers in the field of computer vision (OpenCV, FFmpeg, libdc1394, PGR FlyCapture, OpenKinect, librealsense, CL PS3 Eye Driver, videoInput, ARToolKitPlus, flandmark, Leptonica, and Tesseract) and provides utility classes to make their functionality easier to use on the Java platform, including Android.
新版本并不完全兼容老版本。比如1.5就不完全兼容1.3版本。
比如IplImage类的包名换了：
-
在 1.5版本中，
import org.bytedeco.opencv.opencv_core.IplImage; -
在1.3版本中，
import org.bytedeco.javacpp.opencv_core.IplImage;
package com.downgoon.video.image;
import org.bytedeco.javacv.Frame;
import org.bytedeco.javacv.OpenCVFrameConverter;
// IplImage的包名变更了（在1.5版本相对1.3版本）
import org.bytedeco.opencv.opencv_core.IplImage;
import java.nio.ByteBuffer;
public class ImageConvertor {
public static MatrixImage toMatrix(Frame frame, int width, int height) {
// convert frame to IplImage
OpenCVFrameConverter.ToIplImage converter = new OpenCVFrameConverter.ToIplImage();
IplImage iplImage = converter.convert(frame);
// convert IplImage to MatrixImage
int[] rgbArray = new int[width * height];
extractAndTransferRgb(iplImage, rgbArray);
return new MatrixImage(width, height, rgbArray);
}
@SuppressWarnings("deprecation")
private static void extractAndTransferRgb(IplImage iplImage, int[] rgbArray) {
ByteBuffer iplArray = iplImage.getByteBuffer();
for (int i = 0, iplIdx = 0; iplIdx < iplArray.limit() - 3; i++, iplIdx += 3) {
rgbArray[i] = 0xFF000000 + (iplArray.get(iplIdx + 2) << 16) + (iplArray.get(iplIdx + 1) << 8)
+ iplArray.get(iplIdx);
}
}
