# Creating Models

A model A specific spatial arrangement of a set of features (Blue Locate and Blue Read tools only.) During a post-processing step, the Blue Locate and Blue Read tools can fit all of the features detected in an image to the models defined for the tool. The overall pose and identity of the model is then returned. in Blue Locate and Blue Read is a group of features that appears following a certain pattern. This pattern can be geometrical position (Node Model) or the number of character features that appear glued to each other (String Model in Blue Read). For example, a node model can be a group of 5 features, which form a star formation in terms of their relative geometrical positions. Models are just like labels, so you can consider them a "group label." By creating a model, you define a label consisting of multiple features that appear following a specific pattern in views. Like individual feature A feature is a visually distinguishable area in an image. Features typically represent something of interest for the application (a defect, an object, a particular component of an object). labels, the model should be defined and created (labeled) on each 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.. But the model in Blue Locate and Blue Read is not a neural network and it is not trainable. The model can/cannot be correctly found on each view after processing, and so there can be matched/mismatched models in views.
