# Markings

After training Training is the process that your tool, which is a neural network, is learning about the features (pixels) based on the labels you made. For example, a tool will learn the defect/normal pixels in each image based on the defect/normal labels you drew. The goal of the tool Training is learning enough to give the correct inspection results of whether an unseen image is defective or not. The key to training is to ensure that you include all possible variations within your training set, and that your images are accurately labeled. Training times vary by the application, tool setup and the GPU in the PC being used to train the network., the tool processes the images in the image set and marks the features it finds. The markings graphically represent the statistical results the tool returns. The tool places these graphical markings over characters, features, and areas of the image based on the labels you provided before training. Validate the performance of the tool by comparing the markings with the labels you applied to the same image. The specific markings depend on the tool.

To add more labeled data for further training, convert the markings to labels. Review the markings returned by the tool, and if they are correct, accept the view A view of an image is a region of pixels in an image. Tool processing is limited to the pixels within the view. You can manually specify a view, or you can use the results of an upstream tool to generate a view. and convert the marking Image markings are annotations produced by the VisionPro Deep Learning tools. The markings produced by a tool are the "answers" that the tool obtained when it processed a specific image. You validate the performance of the tool by comparing the markings produced by the tool with the labels that you applied to the same image. As with labels, the specific markings produced depend on the tool. to a label.

To hide and unhide labels or markings in the image:

- Select Cycle through Overlays in the right-click menu in the image.

- Enable or disable Labels or Markings in the overlay checkbox.

- Use keyboard shortcuts. For more information, see Overlay Keyboard Shortcuts.
