Optical Flow algorithm: code for OPENCV read-write Middlebury Web site given optical flow

Middleburyis that everyone who studies the optical flow algorithm cannot use the site,MiddleburyA number of standard test libraries are provided, which greatly advances the optical flow algorithm. Middleburyprovides a standard library whose computed optical stream is saved in the suffix named. Floof the file,Middleburyitself also provides the read. Floin the fileC + +Source code andMatlabsource code. However, the source code is written withOpenCVThe form of the combination is what we expect more, and the following I write read and write. Flothe source code of the document. Relative toMiddleburyGiven the source code, more concise and understandable.

#include "ccc/comcv.h" #include <fstream>void writeflow (mat_<point2f> &flow, String outpath) {Ofstream Out (Outpath, ios_base::binary); string tag = "Pieh";//File Flag Out.write (Tag.c_str (), tag.size ()); Out.write ((const char*) ( &flow.cols), sizeof (int)),///number of rows Out.write ((const char*) (&flow.rows), sizeof (int)),//column number for (int i = 0; i < Flow.rows; i++) for (int j = 0; J < Flow.cols; J + +) {Out.write ((const char*) (&flow (i, J). x), sizeof (float)), Out.write ((const CHA r*) (&flow (i, J).
