查询词典 segmentation nucleus

To achieve the purpose of rapid and accurate milk somatic cell image segmentation, the common methods for color image segmentation are studied.

以实现快速而准确的牛乳体细胞图像分割为目标，研究了具有通用性的彩色图像分割方法。

In this thesis, the theories and methods of GA are analyzed in detail , the trend of GA in recent times is briefly discussed. Because of the importance of image segmentation, two methods of color image segmentation based on GA are proposed. One is the surface of thresholds image segment method, the other is entropic threshold method. Two algorithms are realized through VC++ 6.0. After that, we compare the characteristics of two algorithms and prove that GA can be very well applied to solving image optimal problems.

本篇论文比较详细地论述了遗传算法的基本理论、方法，指出了算法的研究现状，由于图象分割的重要性，提出了两种基于遗传算法的彩色图象分割方法，即阈值曲面分割方法和最佳熵阈值分割方法，通过VC++6.0编程得到了实验验证，比较了两种算法的性能，证明遗传算法完全适用于图象的优化问题。

Firstly, we analyze the color feature of leukocyte images, and then apply an algorithm of segmentation for nucleus extraction based on the HSI color space, which establishes a foundation for the detection of leukocytes. For the localization and the counting of leukocytes, we use an efficient algorithm for labeling connected region to obtain several separate single-cell windows.

首先，我们讨论并分析了白细胞图像的彩色特征，提出了在HSI彩色空间中利用饱和度分割得到细胞核的方法，从而为白细胞的检出奠定了基础，在白细胞的计数和定位方面，主要采用了简捷的连通域标记算法，检出若干包含单个白细胞的细胞窗。

体外培养的单层椎间盘细胞在受力状态下，肌动蛋白的表达减少，细胞的体积缩小，并且肌动蛋白在细胞内重排列。

UGC 5101 is a peculiar galaxy with a single nucleus contained within an unstructured main body that suggests a recent interaction and merger. UGC 5101 is thought to contain an active galactic nucleus an extremely bright, compact core - buried deep in the gas and dust.

ugc5101是一个仅有单独一个星核的特殊星系，并且没有结构性的主体，这一切都说明他是最近才发生接触并碰撞的。ugc4101被认为包含一个活跃的星系核，其非常明亮，非藏紧密—在其深处埋藏着氢气核尘埃。

In the core of the larger spiral structure of NGC 1300, the nucleus shows its own extraordinary and distinct "grand-design" spiral structure that is about 3,300 light-years long. Only galaxies with large-scale bars appear to have these grand-design inner disks — a spiral within a spiral. Models suggest that the gas in a bar can be funneled inwards, and then spiral into the center through the grand-design disk, where it can potentially fuel a central black holes. NGC 1300 is not known to have an active nucleus, however, indicating either that there is no black hole, or that it is not accreting matter.

星系演化除了像两个星系相撞那样的剧烈作用之外，还有自己内部很慢的演化，因为一个星系总会有一些引力不稳定，如上图中的NGC1300，它是一个棒旋星系，这种bar结构导致的引力不完全对称会驱使很多气体和尘埃损失角动量往里面落，我们可以清楚的看到dust lanes，有点像黑洞的吸积，但这个星系是个非活动星系，目前还没有黑洞存在的明确证据，but我相信肯定是有的，没有比在星系中心放一个黑洞再完美不过的事情了，或许这些下落的dust lanes是黑洞发光的开始呢。

Ctive Galactic Nucleus is the hottest research on modern astrophysics. Blazars are one of the most extreme classes of active galactic nucleus, with high luminosity, large amplitude and rapid variability, high and variable polarization, radio core-dominance, and apparent superluminal speeds. Their broad band emission extends from radio up to γ-ray band, and dominated by non-thermal process.

GNs是近代天体物理学研究的热门课题，blazar天体是AGNs中具有极端物理性质的一个子类，它以大振幅快速光变、高且变化的偏振、射电核主导、视超光速运动、全波段非热辐射为主要特征。
