Load Image OpenCV (JavaCV) from byte[] not a file

Question

I have image data coming in from over a socket connection as a byte[]. All examples I have seen using cvLoadImage() is passed a file name. Do I have to save every image to file and re-open it to do the processing? This seems to have a lot of overhead for what needs to happen, is it possible to load the image from the byte[] data?

Answer 1

假设数据以某种标准格式（如JPG或PNG）进行编码，并假设您使用的是JavaCV，对于字节数组b，这也适用：

IplImage image = cvDecodeImage(cvMat(1, b.length, CV_8UC1, new BytePointer(b)));

Answer 2

最后简单的解决方案，您可以使用以下方法从BufferedImage创建一个Image来解决我的问题：

IplImage src = IplImage.createFrom(buffered);
