Can vott read projects from files that has not been originally exported from it?

[AhmedHisham1]

I have a dataset that has been annotated via multiple different annotation software, is it possible to write a script that converts them all into a vott supported format and read them as a new project? so that I can edit and re-annotate them inside vott?

[IanPNewson]

Yes, I've done it. I wrote a model in C# which can be used for this. Let me know if that would be any help and I'll look into uploading it to github.

[AhmedHisham1]

Yes, that would be a great help. Thank you.

Here you go:

It was just for my personal use so there's no documentation, and it only supports images, not video.

Here's some sample code that uses it:

    static async Task Main(string[] args)
    {

        var inDir = new DirectoryInfo(@"C:\Users\Ian\Documents\Projects\Output\StfcBot\StfcScreencopyOverlay");
        var dirPrefix = DateTime.Now.Ticks;

        {
            var outDir = inDir.Subdir($"{dirPrefix}.Predict_{predictThreshold}");

            var project = JsonConvert.DeserializeObject<Project>(File.ReadAllText(@"path to existing project"));
            project.name = outDir.Name;

            project.assets.Clear();
            project.sourceConnection.name = outDir.Name;
            project.targetConnection.name = outDir.Name;

            project.sourceConnection.providerOptions.folderPath =
                project.targetConnection.providerOptions.folderPath =
                    outDir.FullName;

            project.securityToken = null;
            project.useSecurityToken = false;

            var projectFile = outDir.File(outDir.Name + ".vott");

            var tasks = new List<Task>();

            foreach (var file in inDir.GetFiles("*.png"))
            {
                tasks.Add(Task.Run(() =>
                {
                    try
                    {
                        var assetImageFile = outDir.File(file.Name);
                        var assetFile = new AssetFile()
                        {
                            asset = new Asset()
                            {
                                name = file.Name,
                                format = "png",
                                path = "file:" + assetImageFile.FullName.Replace("\\", "/")
                            }
                        };

                        file.CopyTo(outDir.File(file.Name).FullName);

                        lock (project)
                            project.assets.Add(assetFile.asset.id, assetFile.asset);

                        assetFile.asset.size = new VottModel.Size
                        {
                            height = bmp.Height,
                            width = bmp.Width
                        };

                        swAssetFileGeneration.Start();
                        foreach (var result in json.Predictions)
                        {
                            var @class = result.Class;
                            var score = result.Score;
                            var rois = result.Bounds;

                            var rect = rois.ToRect(bmp.Size);

                            //g.DrawRectangle(Pens.Red, rect);
                            //g.DrawString(@class, new Font("Arial", 12), Brushes.Red, rect.Location);

                            assetFile.regions.Add(new Region
                            {

Ahmed Hisham (@AhmedHisham1) Did you solve it? Can you give me bit instruction how to achieve it?

[AhmedHisham1]

Sorry for late reply. No I actually switched to CVAT by intel instead.
