Deep Learning in industrial image processing

Deep Learning has long been an integral part of our everyday lives: from facial and speech recognition on mobile and wearable devices to chatbots, autonomous driving and medical diagnostics. The technology is also being used in numerous manufacturing industries to solve complex process problems, facilitate decision-making, and make intelligent predictions. Deep Learning solutions also play a crucial role in industrial image processing.

Deep learning-based image processing for fast and reliable answers to highly complex questions

Deep Learning is a subfield of Artificial Intelligence (AI). It is based on artificial neural networks (ANN), which are modeled on the human brain. Deep Learning algorithms are trained on large amounts of data and used to recognize and classify structured and unstructured information and patterns. This includes, for example, texts, images, speech and sounds.

Deep Learning based algorithms are to be learned by example and gradually optimize their capabilities. As with human learning, this depends on the wealth of experience. The more data and examples the Deep Learning algorithm has available, the better it becomes.

Advantages of Deep Learning in Machine Vision Applications

Conventional image processing systems are based on programmed, rule-based algorithms. They are capable of performing verification and classification tasks in an automated and repeatable manner that are predictable and thus essentially pre-programmed. However, when unexpected errors or irregularities arise that deviate from the program, or in the case of more complex multivariable testing tasks, traditional image processing reaches its limits. For instance, it cannot distinguish between purely external, tolerable appearance defects and functional defects.

Deep learning-based image processing provides a solution: It is versatile and can distinguish between acceptable deviations and natural fluctuations in similar parts and patterns as well as in complex environments. The algorithm continuously evolves based on new examples without the need for reprogramming the core algorithm.

Whether it’s verification tasks in final assembly, checking foodstuffs, or classifying materials and demanding OCR tasks: deep learning-based image processing is the optimal solution for large deviations, significant deformations, high feature variance, and challenging imaging environments. Through deep learning, the efficiency and accuracy of image processing solutions are significantly improved.

Advantages of Deep Learning:

Through end-to-end learning, deep learning automatically extracts the most relevant features from the data. This reduces the manual effort involved in defining features and leads to more accurate results.

Deep learning models can adapt to changing conditions and environments, allowing for high flexibility in various production settings.

The self-learning algorithms of deep learning can also detect complex errors and anomalies in production processes that often go unnoticed with traditional methods.

The fast and precise inspection through deep learning leads to improved production quality, reduced scrap rates, and increased overall efficiency.

Deep learning solutions can be scaled across various application areas, making them a cost-effective and versatile choice for businesses.
