ICFHR 2010 Handwriting Segmentation Contest

For a binay image:

which has segmentation results:

the output raw image file must be:

In the raw image file, an integer is used for every pixel value and 0s (or <0) correspond to the background and all other IDs (>0) define the resulting different segmentation regions. An example of C++ code to read the output raw imafe files follows:

    int Ix; //Image Width (x=0...Ix-1)
    int Iy; //Image Height (y=0...Iy-1)
    unsigned int *IM_SegmResult; //Pointer to store raw data
    AnsiString SegmResultName; //File that contains the raw data
    FILE *f1;

    IM_SegmResult = (unsigned int *) calloc (Ix*Iy,sizeof(int));
    f1 = fopen(SegmResultName.c_str(),"rb");
    fread(IM_SegmResult,Ix*Iy,sizeof(int),f1);
    fclose(f1);
