Transform the vot dataset into 4 corner format

Transform the vot dataset into 4 corner format

Matlab code to change the 8 value ground truth into 4 corner format: (x1, y1, width, height).

clc;  close all;  clear all;

path = '/Tracking_Benchmark/VOT2018/';

videoFiles = dir(path);

videoFiles = videoFiles(:end);

for i =:size(videoFiles, )

    videoName = videoFiles(i).name;

    disp(videoName);

    gt_path = [path videoName '/groundtruth.txt'];

    gt = importdata(gt_path);

    if size(gt, ) >=

        x = gt(:,::end);

        y = gt(:,::end);

        gt = [min(x,[],), min(y,[],), max(x,[],) - min(x,[],), max(y,[],) - min(y,[],)];

    end

    imgFiles = dir([path videoName '/color/*.jpg']);

    firstFrame = imread([path videoName '/color/' imgFiles().name]);

    targetObject = imcrop(firstFrame, gt(, :));

    imshow(targetObject);

    new_gt_path = [path videoName '/groundtruth_new.txt'];

    fid = fopen(new_gt_path, 'w') ;

    for j =:size(gt, )

        fprintf(fid, '%s', num2str(gt(j, )));

        fprintf(fid, '%s', ',');

        fprintf(fid, '%s', num2str(gt(j, )));

        fprintf(fid, '%s', ',');

        fprintf(fid, '%s', num2str(gt(j, )));

        fprintf(fid, '%s', ',');

        fprintf(fid, '%s \n', num2str(gt(j, )));
