Aurora Vision Studio has three levels of feature complexity. At lower levels we hide advanced features and ones that may be confusing.
Intermediate
Finding Filters
There are many hundreds of ready-for-use filters (tools) in Aurora Vision Studio implementing common image processing algorithms, planar geometry, specialized machine vision tools as well as things like basic arithmetics or operating system functions.
Intermediate
Connecting and Configuring Filters
After a filter is added to the program it has to be configured. This consists in setting its inputs to appropriate constant values in the Properties window or connecting them with outputs of other filters.
Beginner
Creating Macrofilters
Macrofilters play an important role in developing bigger programs. They are subprograms providing a means to isolate sequences of filters and re-use them in other places of the program.
Intermediate
Creating Models for Template Matching
Template Matching tools are very often used as one of the first steps in industrial inspection applications.
Intermediate
Preparing Rectification Transform Map
If you want to perform camera calibration in Aurora Vision Studio, there two basic ways to do that.

Intermediate
Creating Golden Template Models
Golden template technique is the most powerful method for finding objects' defects.
Advanced
Creating User Types
In Aurora Vision Studio it is possible for the user to create custom types of data. This can be especially useful when it is needed to pass multiple parameters conveniently throughout your application or when creating User Filters.
Beginner
Designing HMI
Although image analysis algorithms are the central part of any machine vision application, a human-machine interface (HMI, end user's graphical environment) is usually also very important.
Beginner
Standard HMI Controls
There are several groups of UI components in the HMI Controls catalog:
Beginner
Handling HMI Events
The HMI model in Aurora Vision Studio is based on the program loop. A macrofilter reads data from the HMI controls each time before its first filter is executed. Then, after all filters are executed, the macrofilter sends results to HMI.
Intermediate
Saving a State of HMI Applications
The function of saving HMI applications' state allows to save the configuration, which is currently chosen in respective application controls, and to bring it back at a later time.
Beginner
Protecting HMI with a Password
It is possible to lock the whole HMI or certain parts of it with a password in order to make sure that only authorized users will be able to modify a running program in the production environment.
Intermediate
Creating User Controls
The HMI system of Aurora Vision Studio makes it possible to design user interfaces by composing it from ready-made components, which are called controls.
Intermediate
List of HMI Controls
In the following article you can find all HMI controls to make it easier to find their documentation on the page.
Beginner
Data Types
In Aurora Vision Studio types also play an important role in guiding program construction – the environment assures that only inputs and outputs of compatible types can be connected.
Beginner
Structures
A structure is a type of data composed of several predefined elements which we call fields. Each field has a name and a type.
Intermediate
Arrays
An array is a collection composed of zero, one or many elements of the same type. In Aurora Vision Studio for any type X there is a corresponding XArray type, including XArrayArray. For example, there are types: Point2D, Point2DArray, Point2DArrayArray and more.
Intermediate
Array Synchronization
In many applications several objects are analyzed on a single image. Most typically, in one of the first steps the objects are extracted (e.g. as an array of blobs, edges or occurrences of a template) and then some attributes are computed for all of them.
Beginner
Optional Inputs
Some filters have optional inputs. An optional input can receive some value, but can also be left not set at all. Such an input is then said to have an automatic value.
Beginner
Connections
In general, connections in a program can be created between inputs and outputs of compatible types. This does not mean, however, that the types must be exactly equal.
Beginner
Conditional Execution
Conditional execution consists in executing a part of a program, or not, depending on whether some condition is met. There are two possible ways to achieve this in Aurora Vision Studio:
Intermediate
Types of Filters
Most filters are functional, i.e. their outputs depend solely on the input values. Some filters however can store information between consecutive iterations to compute aggregate results, communicate with external devices or generate a loop in the program.
Beginner
Dealing with Domain Errors
Domain Errors stop the program execution when a precondition of a filter is not met. In general it is not possible to predict all possible Domain Errors automatically and this is responsibility of the user to assure that they will not appear in the final version of the program.
Intermediate

1D Edge Detection (also called 1D Measurement) is a classic technique of machine vision where the information about image is extracted from one-dimensional profiles of image brightness.
Beginner
1D Edge Detection – Subpixel Precision
One of the key strengths of the 1D Edge Detection tools is their ability do detect edges with precision higher than the pixel grid.
Intermediate
Shape Fitting
Shape Fitting is a machine vision technique that allows for precise detection of objects whose shapes and rough positions are known in advance. It is most often used in measurement applications for establishing line segments, circles, arcs and paths defining the shape that is to be measured.
Intermediate

Template Matching is a high-level machine vision technique that identifies the parts on an image that match a predefined template. Advanced template matching algorithms allow to find occurrences of the template regardless of their orientation and local brightness.
