Checking

With these tools, you can check whether objects are present in an image, define a tolerance for errors and return a good/bad judgment for a part:

Common Use Cases

Use this overview to find the right tool to check for the presence of objects. If the objects are scratches or stains you can also use a specialized tool from the category Defect Detection.

Task	Tool	Usage
Train MERLIC to check for the presence of objects with similar gray features in selected coordinates.	Check Presence with Gray Features	Check the presence of objects with gray features in selected coordinates. This is useful if you want to check if objects with a certain color are present or not. If you want to return the position of the objects, use the tool Locate Objects with Similar Gray Values or another appropriate tool from the category Position Determination.
Train MERLIC to check for the presence of objects with similar shapes in selected coordinates.	Check Presence with Matching	Check the presence of objects in selected coordinates with shape-based or correlation based matching. This is useful if you want to check if objects with a certain shape or similar gray value are present at a specific location or not. If you want to return the position of the objects, use the tool Locate with Matching or another appropriate tool from the category Position Determination.
Train one or multiple classes of colors and use the trained data to recognize the colors in specified search areas.	Recognize Color	Detect and verify colors in specified search areas based on previously trained classes of colors. You can use this tool for various use cases such as part verification or selection, verifying proper cable connections, or confirming the installation of the correct resistor.

Usage

Train MERLIC to check for the presence of objects with similar gray features in selected coordinates.

Check Presence with Gray Features

Check the presence of objects with gray features in selected coordinates. This is useful if you want to check if objects with a certain color are present or not.

If you want to return the position of the objects, use the tool Locate Objects with Similar Gray Values or another appropriate tool from the category Position Determination.

Train MERLIC to check for the presence of objects with similar shapes in selected coordinates.

Check Presence with Matching

Check the presence of objects in selected coordinates with shape-based or correlation based matching. This is useful if you want to check if objects with a certain shape or similar gray value are present at a specific location or not.

If you want to return the position of the objects, use the tool Locate with Matching or another appropriate tool from the category Position Determination.

Train one or multiple classes of colors and use the trained data to recognize the colors in specified search areas.

Recognize Color

Detect and verify colors in specified search areas based on previously trained classes of colors. You can use this tool for various use cases such as part verification or selection, verifying proper cable connections, or confirming the installation of the correct resistor.
