Interpolation-based reference image estimation for video display field communication.

Display field communication (DFC) is a frequency-based display-to-camera (D2C) communication technology. The digital display and the camera act as transmitter and receiver, respectively, and data are transmitted in a video via the D2C link. The essence of DFC is to minimize image distortion for the user while concealing data within the image for transmission.

Performance evaluation of data embedding schemes for two-dimensional display field communication.

Display field communication (DFC) is an unobtrusive display-to-camera technology that transmits data within the frequency domain of images, ensuring that the embedded data are hidden and do not disrupt the viewing experience. The display embeds data into image frames, while the receiver captures the display and extracts it. Two-dimensional DFC (2D-DFC) focuses on embedding data in the width and height of an image.

How can we reduce the ischemic time for forearm replantation? Tips to simplify the bone fixation.

Purpose: Ischemic time is a key factor in satisfactory functional results after forearm replantation. In this study, we provide a detailed description of our surgical technique, the temporary screw plate fixation technique, which aims to reduce ischemic time.

Methods: From June 2007 to June 2017, we performed a retrospective study of 20 patients who underwent forearm replantation.

Surgical outcomes of segmental diaphyseal forearm fractures in adults: a small case series on plate osteosynthesis, intramedullary nailing, and other surgical methods.

Background: Segmental fractures often result from high-energy or indirect trauma that causes bending or torsional forces with axial loading. We evaluated surgical outcomes of patients with forearm segmental diaphyseal fractures.

Methods: We retrospectively analyzed data from patients with forearm segmental fractures for which they underwent surgery at the Pusan National University Trauma Center from March 2013 to March 2022.

Sensory Reconstruction of a Posterior Heel Defect Using a Proximally Based Sensate Medial Plantar Flap with Retrograde Nerve Cleavage Technique.

Reconstruction of posterior heel defects is important because it requires thick and durable skin that can withstand pressure and shear from shoe and bed contact. Therefore, the sensate flap could be a better option for the defect. This paper reports on the safety of a medial plantar sensory flap for these defects as well as an objective measurement of the sensation of the medial plantar flap and the plantar surface distal to the donor site.
