Abstract: Provided is a deep learning-based panoptic segmentation accelerated processing technique using a complexity-based RPN skip method. An image segmentation system includes: a first processing unit configured to extract dynamic objects in an instance segmentation method by using an extracted feature; a calculation unit configured to control to skip some areas of the feature extracted at the network by the first processing unit, on the basis of complexity of the input image; a second processing unit configured to extract static objects in a semantic segmentation method by using the feature extracted at the network; and a fusion unit configured to fuse a result of extracting by the first processing unit and a result of extracting by the second processing unit. Accordingly, the panoptic segmentation method can be easily performed even in an embedded environment by reducing complexity for panoptic segmentation processing by reducing a calculation burden.

Abstract: Proposed are a method for data interworking between an application and an IoT device, and a middleware device for performing the method. The method may include generating matching information between an IoT device and a network protocol used by the IoT device based on IoT device profile information, and analyzing a request message received from an application device to extract IoT device information of a request target. The method may also include generating a request packet conforming to a network protocol used by a target IoT device based on the request message, the IoT device information of the target request, and the matching information, and transmitting the request packet to the target IoT device. The method may further include converting a response packet transmitted by the target IoT device in response to the request packet into a response message, and transmitting the response message to the application device.

Abstract: A multi-channel micro peripheral nerve sensor for measuring a neurosignal with low noise is proposed. The multi-channel micro peripheral nerve sensor may include a substrate, an analog-digital (AD) converter, and a signal acquisition unit. The substrate may be combined with each cut surface of a severed nerve and include channels into which nerve cells are inserted. The AD converter may be combined with the substrate, be electrically connected to the channels, receive analog neurosignals from the nerve cells, and convert the analog neurosignals into digital signals. The signal acquisition unit may be electrically connected to the AD converter and acquire the digital signals from the AD converter.
