This paper presents a deep learning approach to Kaggle Carvana Image Masking Competition, which aims at extracting the car objects in high quality images with the background removed. We formulate the background extraction problem as an image segmentation problem. In this challenge, we have evaluated different U-Net architectures. We have ...

Keypoint detection is critical in image recognitions. Deep learning such as convolutional neural network (CNN) has recently demonstrated its tremendous success in detecting image keypoints over conventional image processing methodologies. The deep learning solutions, however, heavily rely on labeling target images for their reliability and accuracy. Unfortunately, most image datasets ...

This work analytically investigates the wireless channel characteristics at 60 GHz in five aspects: path loss on the range of a wireless communication system, multi-path fading, spatial diversity, high peak-to-average power ratio of orthogonal frequency division multiplexing (OFDM), and detection time of clear channel assessment. The analysis is conducted in ...

Rate adaptation in wireless networking aims to seek the optimal data transmission rate most appropriate for current wireless channel conditions to make full use of the channel potentials. It is important in wireless networks because (1) most of them support multiple data rates, and (2) wireless channel is unstable with ...

Lifetime is a crucial issue for Multi-hop wireless network powered by size-limited batteries. There have been few algorithms proposed to solve such network lifetime challenge. Furthermore, the application of flexible channel coding redundancy scheduling to improve energy-balancing and energy-efficiency has seldom been reported in literature. In this paper, we propose ...

Routing metrics are critical for selecting a path with maximum throughput in wireless multi-radio multi-hop mesh networks. Due to the unique characteristics of wireless mesh networks, such as various wireless losses, data transmission rates and transmission channels, the traditional minimum hop count metric does not perform well. To address this ...

Future multimedia applications in wireless multimedia sensor networks impose stringent and diverse Quality of Service (QoS) requirements, which demands a cross-layer architecture. However, the cross-layer optimization for multimedia delivery is not easy to be implemented in resource limited Wireless Multimedia Networks, as QoS requirements may be qualitative, or even fuzzy. ...

Rate adaptation consists of using the optimal rate for a given channel quality: the poorer the channel quality, the lower the rate should be. Multiple rate adaptation schemes were proposed and studied so far. The first generation rate adaptation schemes perform well in collision free environments and manage quite well ...

IEEE 802.11 standard has evolved from the basic transmission rates in early days to multiple rates today with advanced encoding and antenna techniques. The performance of IEEE 802.11 wireless networks is supposed to benefit from the support of multiple transmission rates. To take advantage of multiple available rates, a strategy ...

Wireless communications benefit from multiple data rates under unstable channel conditions. More efficiently modulated user information results in higher overall data rates, but more error-prone information is received. Thus, it is highly important to adaptively choose a proper data rate so as to optimize network performance based on instantaneous channel ...

It is generally admitted that the performance of ad hoc networks can be quite poor and disappointing due to high contention and lack of an optimal MAC protocol. Here we investigate one approach to alleviate the contention: allowing nodes to communicate simultaneously on different channels by configuring them with multiple ...

In recent years, extensive research effort has been devoted to TCP congestion control in hybrid wired-wireless networks. A general agreement is that the TCP sender should respond differently to wireless losses and disconnection, i.e., not slow down as drastically as for congestion losses. Thus, research focus for wireless TCP congestion ...
