這篇文章將為大家詳細(xì)講解有關(guān)怎么將YUV轉(zhuǎn)換為jpg圖像,文章內(nèi)容質(zhì)量較高,因此小編分享給大家做個(gè)參考,希望大家閱讀完這篇文章后對(duì)相關(guān)知識(shí)有一定的了解。
代碼如下:
# define _CRT_SECURE_NO_WARNINGS #include <string> #include <iostream> #include <fstream> #include <cv.h> #include <highgui.h> #include <opencv2/core/core.hpp> #include <opencv2/highgui/highgui.hpp> #include <opencv2/imgproc/imgproc.hpp> 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", iFrameNum); imwrite(outName, frameRGB); } free(InData); free(uvData); fclose(fpIn); return 0; }
關(guān)于怎么將YUV轉(zhuǎn)換為jpg圖像就分享到這里了,希望以上內(nèi)容可以對(duì)大家有一定的幫助,可以學(xué)到更多知識(shí)。如果覺得文章不錯(cuò),可以把它分享出去讓更多的人看到。
