Multidimensional sensors, such as digital camera sensors in the visual sensor networks
VSNs generate a huge amount of information compared with the scalar sensors in the …

This paper deals with image compression over Wireless Camera Sensor Networks (WCSNs)
in order to decrease the energy consumption of sensors and thus to maintain a long network …

JPEG compression based on the discrete cosine transform (DCT) is a key building block in
low-power multimedia applications. We use approximate computing to exploit the error …

Video applications are being a key component to enhance traditional wireless sensor
networks (WSN) applications. As a result, sensor network researchers need adequate and …

Wireless Multimedia Sensor networks (WMSNs) have shifted the focus from scalar wireless
sensor networks to networks with multimedia devices that are capable to retrieve video …

在资源受限的无线多媒体传感器网络中存在大量的视频数据需要处理和传输.
为充分地利用这些有限的资源, 需要设计一个能够综合考虑能量消耗和压缩率 …

Abstract Discrete Cosine Transform (DCT) is known as one of the most significant,
fundamental, and prevailing transforms in data compression, watermarking, and medical …

This article presents a lightweight image compression algorithm explicitly designed for
resource-constrained wireless camera sensors, called TiBS (tiny block-size image coding) …

With Visual Sensor Networks (VSN), designers must respect strict constraints on energy
consumption, which make compression standards, such as JPEG, not energy-beneficial to …

Internet of Things systems can not successfully realise the notion of ubiquitous connectivity
of everything if they are not capable to truly include multimedia things. In this paper, we …
