DL Model Performance

As shown in the image below, the DL model does not recognize the top layer of the workpieces correctly. What might be the issue?

After checking the vision project, we found that the ROI for the DL model has been changed to a customized ROI. In general, we recommend using the default ROI since the model is trained with the default ROI. Moreover, the customized ROI did not fully cover the range of the bin, which will lead to misrecognition.

With the default ROI, the DL model can now recognize the top layer workpieces correctly.
