今天小编就为大家分享一篇YUV转为jpg图像的实现，具有很好的参考价值，希望对大家有所帮助。一起跟随小编过来看看吧
调用opencv库，将yuv图像转为jpg图像。
代码如下：
# define _CRT_SECURE_NO_WARNINGS #include #include #include #include #include #include #include #include using namespace cv; using namespace std; int main() { int iWidth; int iHeight; int iFrameNum; int iImageSize; iWidth = 640; iHeight = 480; char *inputFileName = "640x480_YUV400.yuv"; FILE *fpIn; if (fopen_s(&fpIn, inputFileName, "rb")) { cout << "File Open Failed!\n"; system("pause"); exit(1); } iImageSize = iWidth * iHeight; unsigned char *InData = (unsigned char*)malloc(iImageSize * sizeof(unsigned char)); unsigned char *uvData = (unsigned char*)malloc(iImageSize / 2 * sizeof(unsigned char));//uv memset(uvData, 128, iImageSize / 2); Mat frameYUV(iHeight * 3 / 2, iWidth, CV_8UC1); Mat frameBGR; Mat frameRGB; Mat frameYUV420; char outName[128]; iFrameNum = 0; while (1) { size_t size = fread(InData, sizeof(unsigned char), iImageSize, fpIn); if (size == 0) { cout << "Read Frame Fail!\n"; system("pause"); break; } memcpy(frameYUV.data, InData, iImageSize); memcpy(frameYUV.data + iImageSize, uvData, iImageSize / 2); cvtColor(frameYUV, frameBGR, CV_YUV2BGR_I420); cvtColor(frameBGR, frameRGB, CV_BGR2RGB); imshow("video", frameRGB); waitKey(1); cout << iFrameNum++ << " Frame Processed\n"; sprintf(outName, "outFile/%d.jpg-600", iFrameNum); imwrite(outName, frameRGB); } free(InData); free(uvData); fclose(f<strong style="color:transparent">来源gaodaima#com搞(代@码网</strong>pIn); return 0; }
