but why?

And I've noticed if providing null(so no downsampling is done) as the MaxSize:

PaddleSharp/src/Sdcb.PaddleOCR/PaddleOcrDetector.cs

Lines 169 to 171 in 5713096

	private static Mat MatResize(Mat src, int? maxSize)
	{
	if (maxSize == null) return src.Clone();

Detecor.Run() will consume several gigabytes of memory before return.

but why?

Because TensorRT default size suggested 1536

But not everyone is using NVIDIA TensorRT.
