A Novel Merging Criterion Incorporating Boundary Smoothness and Region Homogeneity for Image Segmentation-Abstract
A novel joint region merging criterion combining region homo-geneity and boundary smoothness is proposed. Previous watershed segmentation method which utilizes region homogeneity or edge integrity or both gives good results in some cases. However, for complex scenes such as images of a vehicle with irregular roadside objects reflected on the window panes, it tends to give undesired segmentation results with region boundaries not residing on real physical boundaries. Aiming at improving the segmentation of these complex scenes, we propose the incorporation of an additional measure of boundary smoothness into a new joint criterion. Based on this, an affine transform invariant measure of the smoothness of boundaries is developed, which is the equivalent width of the energy distribution function over frequencies, obtained from Fourier descriptors of the boundary. Experimental results and evaluation are presented in this paper to demonstrate the merits of the proposed method.

Description: Cost effective digital cameras use a single-image sensor, applying alternating patterns of red, green, and blue color filters to each pixel location. The problem of reconstructing a full three-color representation of color images by estimating the missing pixel components in each color plane is called demosaicking (see Figure 1 ). In this report we will examine some traditional methods of demosaicking versus some new frequency domain methods. We will discuss the Bilinear and Adaptive Bilateral algorithms, and then compare them with two newer frequency domain algorithms: the Homogeneity algorithm and the Alternating Projections algorithm.

Description: Abstract—Denial of Service attacks are presenting an increasing threat to the global inter-networking infrastructure. While TCP’s congestion control algorithm is highly robust to diverse network conditions, its implicit
assumption of end-system cooperation results in a well-known vulnerability to attack by high-rate non-responsive fl ows. In this paper, we investigate a class of low-rate denial of service attacks which, unlike high-rate attacks, are diffi cult for routers and counter-DoS mechanisms to detect. Using a combination of analytical modeling, simulations, and Internet experiments, we show that maliciously chosen low-rate DoS traffi c patterns that exploit TCP’s retransmission timeout mechanism can throttle TCP fl ows to a small
fraction of their ideal rate while eluding detection. Moreover, as such attacks exploit protocol homogeneity, we study fundamental limits of the ability of a class of randomized timeout mechanisms to thwart such low-rate

Description: qtdecomp divides a square image into four equal-sized square blocks, and then tests each block to see if it meets some criterion of homogeneity. If a block meets the criterion, it is not divided any further. If it does not meet the criterion, it is subdivided again into four blocks, and the test criterion is applied to those blocks. This process is repeated iteratively until each block meets the criterion. The result can have blocks of several different sizes.

Description: 分割树的实现(1.4版本)
==============================================
这个软件包包含MATLAB实现了低层次多尺度
[1]中描述的分层分割算法。
介绍
------------
低级别的图像分割的目标是检测到的所有图像区域
不论其形状,大小和内部同质化的水平。在这里,

区域内的变化。-Segmentation Tree Implementation (version 1.4)
==============================================
This package contains a MATLAB implementation of the low-level multiscale
hierarchical segmentation algorithm described in [1].
Introduction
------------
The goal of low-level image segmentation is to detect all image regions
regardless of their shapes, sizes, and levels of interior homogeneity. Here, a
region is modeled as a connected set of pixels that is surrounded by ramp edge
discontinuities where the magnitude of these discontinuities is large compared
to the variation inside the region.

Description: 米国人写的先进雷达信号处理技术论文,空时二维处理技术在机载雷达中的应用文献。-This research develops a space-time adaptive processing (STAP) radar model
for side-looking (SL) arrays with platform maneuver incorporation, and examines ma-
neuver effects on Matched Filter (MF) performance and sample support homogeneity
for linear and planar arrays at various ranges. A primary assumption of most STAP
models is the absence of platform maneuver during the coherent processing interval
(CPI). This research abandons the platform stationarity assumption, allowing plat-
form pitch, roll, and yaw during the CPI. Maneuver rates (set to 800◦ /sec) are held
constant throughout the CPI and each maneuver type is examined individually.

Description: This paper presents a new cluster validity index for nding a suitable number of
fuzzy clusters with crisp and fuzzy data. The new index, called the ECAS-index, contains
exponential compactness and separation measures. These measures indicate homogeneity
within clusters and heterogeneity between clusters, respectively. Moreover, a fuzzy c-mean
algorithm is used for fuzzy clustering with crisp data, and a fuzzy k-numbers clustering is
used for clustering with fuzzy data. In comparison to other indices, it is evident that the proposed index is more effective and robust under
different conditions of data sets, such as noisy environments and large data sets.
