yuv nv12图像保存颜色偏紫

如果resize先于cvtColor做，

Mat imgYUV = Mat(yuv_info.height * 3 / 2, yuv_info.width, CV_8UC1, yuv_data);
resize(imgYUV, imgYUV, Size(imgYUV.cols / 4, imgYUV.rows / 4), 0, 0, INTER_LINEAR);
Mat read_image_0;
cvtColor(imgYUV, read_image_0, CV_YUV2BGR_NV12);

保存的结果图像会偏紫，看上去蓝色或红色都变成了紫色，原因是resize把nv12格式中的U分量和V分量合并了。正确写法如下：

Mat imgYUV = Mat(yuv_info.height * 3 / 2, yuv_info.width, CV_8UC1, yuv_data);
Mat read_image_0;
cvtColor(imgYUV, read_image_0, CV_YUV2BGR_NV12);
resize(read_image_0, read_image_0, Size(read_image_0.cols / 4, read_image_0.rows / 4), 0, 0, INTER_LINEAR);
imwrite("/tmp/test.jpg", read_image_0);

As the employer of Mr. Peterson, please accept my sincere apologies for the communication sent by Mr. Peterson to you. Mr. Peterson's communication was inappropriate and inconsistent with our company's values. Our company is an equal opportunity employer and it is proud of its diverse workforce. Indeed, the majority of the employees performing the work for which you applied speak English as a second language and they represent a wide range of backgrounds and nationalities. While it is true that communicating effectively in English is an important part of the job in question, the manner in which Mr. Peterson communicated with you was highly inappropriate and following our investigation he is no longer employed with the company. Thank you for bringing this to our attention and I hope you will accept my sincere apology.

Props to you.
