Machine Vision: MVTec Presents New and Optimized Features With Halcon 20.05
April 8, 2020 | MVTecEstimated reading time: 2 minutes
MVTec Software GmbH, the leading international provider of machine vision software, will launch a new Progress release of its standard software HALCON on May 20, 2020. HALCON 20.05 offers both entirely new features and updated technologies from the previous version, which can be used to further optimize machine vision processes. The bar code reader has been improved by an advanced decoding algorithm, which increases the decoding rate when reading codes with very thin bars. Thanks to this, it is now possible to even read codes with bars smaller than one pixel. With HALCON 20.05, training for all deep learning technologies can now be performed on a central processing unit (CPU). By removing the need for a dedicated graphics processing unit (GPU), standard industrial PCs that could not house powerful GPUs can now be used for training. Customers benefit from significantly greater flexibility regarding the implementation of deep learning, because training can now be performed directly on the production line.
Another new development is that the generic box finder released with the previous version has been improved in terms of robustness, performance, speed, and usability: With MVTec HALCON 20.05, it is now much easier to find boxes of different shapes and sizes reliably. In addition, the Grad-CAM-based heatmap (Gradient-weighted Class Activation Mapping) can now be calculated on the CPU without significant speed drops. This means that users are now able to analyze directly which parts of an image influence the deep learning network's classification decision. Moreover, the anomaly detection has been significantly improved in the current HALCON version. Training the network is now up to ten times faster, and inference speed has also been improved. Trained networks now also require less memory and disk space, which makes the feature more viable for use on embedded devices.
Surface-based 3D matching improved
Another new function improves processes in manufacturing, where workpieces must be located robustly and accurately to allow for further processing. Characteristics such as small holes are often the only unique features to find the correct orientation of the object. HALCON's surface-based 3D matching can now make use of such features to improve the accuracy and robustness of the matching results.
"More than ever before, MVTec HALCON 20.05 demonstrates the benefits that the short release cycle of our HALCON Progress Edition has to offer. In addition to the fast delivery of new features, we can also incorporate the latest customer feedback into the software product within a short period of time. This approach allows us to quickly optimize functionalities and thus make them even more attractive to our customers," explains Mario Bohnacker, Technical Product Manager HALCON at MVTec.

Flexible Thinking: Musings on High Density Interconnections
10/30/2024 | Joe Fjelstad -- Column: Flexible ThinkingPeople have been using high density interconnection (HDI) technology since the early 1980s, although it was not called HDI until the late 1990s. In the 1970s, ’80s, and early ’90s, engineers used HDI methods to develop hybrid circuits, which were later referred to as multichip modules (MCMs). These were arguably the first instantiation of heterogeneous interconnection technology, which has been the industry buzzword for almost a decade. These devices are a way of integrating multiple chips—both integrated circuits and discrete devices (resistors, capacitors, and inductors)—into a single package, typically using ceramic substrates with layers of insulation and metallic inks (often gold) and firing them at high temperatures.

Highlights of the ICT 50th Anniversary Symposium
10/24/2024 | Pete Starkey, I-Connect007Why does it always rain when I attend these events? Temperatures were dropping, daylight was shrinking, and there were seasonal colour changes in wet hedgerows as I travelled to Gloucestershire for the 50th Anniversary Symposium of the Institute of Circuit Technology at Puckrup Hall near Tewkesbury in mid-October. It was a memorable occasion: Nostalgic for my contemporaries who remembered our industry at its most prosperous, technically outstanding in the quality and significance of presentations to an attentive audience of printed circuit professionals, and complemented by the sharing of ideas, information, and trade gossip within a friendly community at the evening gathering.
