![]() ![]() ![]() Transformer-based models with different hyperparameter values were designed and compared, and their impact on accuracy was analyzed. ![]() This article explores the role of vision Transformer networks in the extraction of building footprints from very-high-resolution (VHR) images. How we should configure them for the extraction of objects in VHR images and how they affect the accuracy of networks are topics that have not been sufficiently investigated. Image patches, linear embedding, and multi-head self-attention (MHSA) are several of the main hyperparameters. Vision Transformer networks have different architectures to CNNs. Vision Transformer networks have shown significant improvements in performance compared to traditional convolutional neural networks (CNNs) in semantic segmentation. ADVANCED POWER FACTOR CORRECTION (PFC) UNIVERSAL POWER SUPPLY – The most advanced power supply in an installation amplifier delivers power more efficiently in almost any condition than anyone else, resulting in less power dissipated and less heat in your racks.Semantic segmentation with deep learning networks has become an important approach to the extraction of objects from very high-resolution remote sensing images.Incorporating the fans into the amplifier brick design maximizes cooling while minimizing wasted energy and noise. EFFICIENT COOLING DESIGN – Highly efficient internal cooling fans provide airflow to the most heat-generating parts.REMOTE ON/OFF INTERFACE – Save power by integrating the amplifier into a control system so you can easily turn it on and off.BRIDGEABLE CHANNEL PAIRS – Unlike amps from other manufacturers, the DCi Series channels are bridgeable – even in 100Vrms mode – which means even more adaptability for higher power applications such as subwoofers.This means better design flexibility since DCi powers all loads on a channel-by-channel basis. CHANNEL INDEPENDENT HI-Z/LOW-Z SELECTION – Drive either one or two speakers in low-Z mode, or literally hundreds of speakers in high-Z mode (70Vrms or 100Vrms).With no need for a step-up transformer at the output, the DCi produces higher audio quality much more efficiently. DIRECT DRIVE CONSTANT VOLTAGE – Save money by using smaller gauge wiring to drive the speakers using either 70V rms or 100Vrms.More channels in one box allow smaller infrastructure rooms that can reduce operational costs while giving you the utmost in installation flexibility. TRUE RACK DENSITY – Power points of 300W or 600W in 2-/4-/8-channel configurations – all in a 2 Rack Unit form factor.Installed Sound, Recording Broadcast, Cinema. Output Power: Bridge Mono Mode - All Channels Driven DCi Analog Model Output Power: Dual Mode - All Channels Driven DCi Analog Model Versatile, compact and highly energy-efficient, DCi Series amplifiers continue the unbroken Crown tradition of leadership in professional and commercial power amplifier technology. DCi Series amplifiers are designed, engineered and manufactured to the industry’s highest quality standards, and provide system integrators with the advanced features and flexibility required for challenging 21st century installed sound applications.
