In this paper, a lossless image compression technique using prediction errors is proposed.
To achieve better compression performance, a novel classifier which makes use of wavelet …

The image quality is extremely important in the catenary fault diagnosis based on the image
processing. In order to improve image visual effects, this paper proposes a catenary image …

Existing scalable wavelet image coding approaches, such as set partitioning in hierarchical
trees and its derivatives, employ a memory-intensive tree-based coding structure. Existing …

Multiscale geometric analysis (MGA) is not only characterized by multi-resolution, time-
frequency localization, multidirectionality and anisotropy, but also outdoes the limitations of …

针对Contourlet 变换在方向滤波分解过程中没有结合图像自身特性且各高频子带方向分解数目
固定的问题, 提出将熵作为描述图像高频子带纹理/边缘特性的指标, 对Contourlet …

为了实现长距离, 大范围的温度在线监测, 设计了基于啁啾调制技术的光纤布拉格光栅温度监测
系统. 采用线性啁啾结构获得更大回波带宽, 从而在单根光纤上集成更多的FBG 探测器 …

Strain and temperature are two main parameters in fiber grating system, while there are
cross-sensitive problems. In order to obtain this two-parameter at the same time, and to …

We propose a non-redundant tunable-Q contourlet transform for image coding. Existing non-
redundant contourlet transforms use multiscale pyramids to iteratively decompose an image …

Directional decompositions of the Contourlet transform do not take into account the
characteristics of the image itself and the number of directional decompositions in each high …
