Neuro-T
Our deep learning vision software trains models for image recognition. Its intuitive GUI and auto deep learning technology makes it possible for non-experts to create high-quality models with just a few clicks.

Neuro-R
Our deep learning vision software utilized to run models.
Models are deployed and embedded to possibly any device.

Neurocle is a company specializing in deep learning-based vision software, has released 2.3 version of deep learning deep learning vision software Neuro-T & Neuro-R, which includes a variety of new features.
Neuro-T and Neuro-R are deep learning vision software that can be used by non-experts. It is provided in an intuitive graphical UI (GUI)-based design method so that even non-experts can utilize deep learning vision technology. Users are allowed to design processes that automate appearance defect inspection, medical image analysis, and logistics packaging inspection.

What is worthy of noticing about the newly released version 2.3 of Neuro-T & Neuro-R is that Fast Retraining function that enables rapid maintenance/repair is added. There were many customers confronted with difficulty of maintenance/repair of the inspection process due to the addition of defective types or quick change of the product in the production process. The majority of these customers tried to solve this problem through Transfer Learning. Transfer learning is a method of learning images by adding data to existing models, and often does not clearly reflect new changes due to the many constraints of existing models. However, the Fast Retraining function is a learning method that utilizes existing architectures and hyperparameters when learning data is added or changed, allowing data to be re-learned across the board, leading to clear and fast maintenance. Neurocle also present a method to increase the accuracy of image learning by adding pre-processing features to set up ROI(Region of Interest) and MASK(area excluded), as well as reflect improvements required by customers in previous versions, such as adding function to remove data augmentation, improving Labeling Tab UI, and adding shortcuts.

Neurocle CEO Hongsuk Lee said, “Neurocle has been providing customers with the process of automatically generating models by utilizing auto deep learning algorithms since the early version, thereby securing the convenience of learning.” “We wanted to further maximize the efficiency and economy of the deep learning project by adding fast retraining function and image pre-processing, considering the situation of relearning due to changes in learning data,” he said. Meanwhile, Neurocle has recently succeeded in registering a number of core technology patents based on innovative products, and has successfully signed contracts with leading conglomerates and university hospitals, posting sales growth of more than 200% annually. In addition, it has been recognized at home and abroad, winning the Korea Impact Tech Award hosted by the Ministry of Science and ICT and the Innovators Award hosted by Vision System Design.

More resolution! More image quality!
With high-resolution machine vision systems, the smallest object structures are classified in the highest quality. However, all sensors available on the market with resolutions with 100 megapixel and above only use a rolling shutter. The new shr661 CMOS camera from SVS-Vistek can confidently be called a milestone in machine vision, because it offers an enormous resolution of 127 megapixels and, despite this extremely high resolution, works with a global shutter. It thus enables new applications in numerous fields of use.

• Global Shutter – why?
  CMOS camera sensors can be built in two different ways: With rolling shutter or with global shutter. With global shutter, in simple terms, all pixels of the sensor are exposed simultaneously and then read out. With rolling shutter, the sensor lines (overlapping) are exposed and read out one after the other. Rolling shutter sensors are technically easier to implement, which is why highest resolution cameras typically use this shutter variant. However, the time-shifted exposure of the lines in the rolling shutter results in different exposure times in the image field, which can lead to distortions and lighting-related pattern artifacts. Therefore, in applications with moving objects, the use of such sensors is very limited. In most machine vision applications, global shutter sensors are therefore used wherever possible. The shr661 is the first camera in this resolution class that can inspect moving objects (e.g. test specimens on a conveyor belt).
• First on the market
  As a recognized specialist for high-resolution industrial cameras, SVS-Vistek is the first manufacturer worldwide to show a camera with 127 megapixels and global shutter – the shr661. It is based on the Sony Pregius sensor IMX661 with a pixel size of 3.45 µm edge length. With this camera, all those tasks where a global shutter is helpful or even necessary are suddenly possible, even in the highest resolution. The image quality of the shr661 is the current high-end of industrial cameras.
• Industry friendly
  The design, which is consistently geared towards industrial use, facilitates integration into industrial applications. A wide temperature range in operation is made possible by SVS-Vistek’s proven, highly effective cooling system. The excellent thermal management ensures an even temperature distribution on the sensor and excellent image homogeneity with outstanding dynamic range. Despite the large sensor, the camera has a small, integration-friendly housing. The 3.45 µm pixels are not critical when choosing suitable lenses. And the high resolution of 13392 x 9528 pixels, together with the global shutter, reproduces the finest structures even with moving objects.
• State of the art interfaces and high end features
  The high data rate of the huge sensor of up to 2.2 GB/s requires modern, fast interfaces. By using the powerful CoaXPress-12 interface, the shr661 transmits up to 17 fps and in the version with 10GigE interface 6.5 fps are achievable.
  Industrial cameras with the highest resolutions, such as SVS-Vistek’s shr661, benefit especially from Flat Field Correction and Defect Pixel Correction, which can also be adapted by the user to the respective scenario. The shr661 can be operated with 8, 10 or 14 bit colour depth. In all colour depths, the outstanding homogeneity of the image is worth emphasizing.
• Easy to integrate
  As you would expect from SVS-Vistek cameras, integration of such a high performance camera is very simple. The I/O framework with multiple inputs and four power-out outputs supports precise triggering as well as sequencers and logical operators. The power-out outputs with the built-in strobe controller can drive LED lighting directly. The GenICam interface with GenTL interface enables easy integration into all major machine vision software packages within only a few minutes. SVS-Vistek’s shr661 is currently available as a demonstrator.

Canon announced today the launch in Japan of the LI8020SAC (color) and LI8020SAM (monochrome), two new APS-H size (approximately 29.4 mm x 18.9 mm) CMOS sensors capable of image capture with a resolution of approximately 250 megapixels (19,568 x 12,588 pixels).

The new CMOS sensors achieve an ultra-high resolution of approximately 250 megapixels, enabling the image capture of wide areas while also preserving fine details throughout the image. With a pixel pitch of 1.5 μm (micrometers), a total of approximately 250 million pixels can be accommodated on an APS-H size sensor, making the sensors suitable for a wide variety of applications. From inspections of flat-panel displays (FPD), which continue to require increased precision due to the growth of 4K and 8K technology, to industrial inspections, video productions and digital archiving, wide-area monitoring and microscopes, the potential uses for the new sensors help meet a wide range of user needs.

The LI8020SAC and LI8020SAM realize image capture with an ultra-high resolution of 250 megapixels—approximately 125 times that of full HD (1920 x 1080 pixels) and approximately 30 times that of 4K (3840 x 2160 pixels)—allowing users to crop selected areas and digitally zoom to expand images while still retaining sufficiently high resolution.

As CMOS sensors increase in pixel count, the amount of signal also increases, leading to such problems as signal delay and slight discrepancies in timing. However, the new sensors, while delivering an incredibly high pixel count of approximately 250 million, features miniaturized circuitry and enhanced signal processing technology to achieve an ultra-high pixel readout speed of approximately 1,250 megapixels per second. This enables the sensors to realize ultra-high resolution image capture at up to approximately 5 frames per second (FPS), even during full pixel readout.
