Translate C++ program to Javascript

I need this translated to Javascript from C++: #include <opencv2\highgui\highgui_c.h> #include <opencv2\imgproc\imgproc_c.h> #include <cstdio> #include <map> int main(int argc, char *argv[]) { if (argc < 2) { printf("Usage: %s image_file\n", argv[0]); return 0; } const char* inFilename = argv[1]; uint64 id = 0; IplImage* inImg = cvLoadImage(inFilename); if (inImg == NULL) { printf("Error opening %s\n",inFilename); return -1; } IplImage* hsv = cvCreateImage(cvGetSize(inImg), IPL_DEPTH_8U, 3); cvCvtColor(inImg, hsv, CV_RGB2HSV); IplImage* v = cvCreateImage(cvGetSize(inImg), IPL_DEPTH_8U, 1); cvSplit(hsv, NULL, NULL, v, NULL); CvSize size = cvGetSize(inImg); [login to view URL] -= [login to view URL] % 8; [login to view URL] -= [login to view URL] % 8; IplImage* resv = cvCreateImage(size, IPL_DEPTH_8U, 1); cvResize(v,resv); CvSize boxSize = cvSize([login to view URL],[login to view URL]); IplImage* mask = cvCreateImage(size, IPL_DEPTH_8U, 1); unsigned char mean[8*8]; for (int ii = 0; ii < 8; ++ii) { for (int jj = 0; jj < 8; ++jj) { cvSet(mask,cvScalar(0)); cvDrawRect(mask,cvPoint(jj*[login to view URL],ii*[login to view URL]),cvPoint((jj+1)*[login to view URL], (ii+1)*[login to view URL]),cvScalar(255),-1); // fprintf(log,"%3u ",(unsigned)cvAvg(resv,mask).val[0]); mean[ii*8+jj] = (unsigned char)cvAvg(resv,mask).val[0]; } //fprintf(log,"\n"); } //FILE* log = fopen("[login to view URL]","w"); unsigned jj = 0; for (int ii = 0; ii < 8*8 - 1; ++ii) { int dif = (int) mean[ii] - (int) mean[ii+1]; if (dif >= 0) { id |= 1LL << jj++; } else jj++; //fprintf(log,"%d\n",dif); } printf("%llu\n", id); //fclose(log); } Max 24 hours. Milestone will be set.
