Bitmap data

[nfnpmc]

What is (I assume a variable) Enumerable and how do you get it from a Bitmap or Image, neither of which is Enumerable? Two loops to examine the pixels and put it into a linear array?

Hi @nfnpmc ,

The data in ML.NET is always passed as an IDataView. We have a convenience method to convert an enumerable of objects of a given type to an IDataView by converting each field in the given type to a column in the IDataView. Currently, this method does not yet support classes with Bitmap fields, but there is a PR #3263 to add this support.

Does this answer your question?

Yes, as you can see here, after merging #3263, this issue can be closed.

Yes, but, the loading from a filename generates, AFAIK, a bitmap for input, which is then Transformed by ExtractPixels.Is there any way to miss out the text loading and pass the bitmap to ResizeImages then ExtractPixels?Someone suggested converting the Image to a tensor and passing that as a vector (of unknown length), is this a viable option?

How, when, will this be available to update Visual Studio, please?

I am also looking for this update, I think? In my data structure model I would like to have a column of Bitmap:

[ColumnName("Bitmap")]
public Bitmap bitmap; // https://github.com/dotnet/machinelearning/issues/3784
