Conserved motifs are found in many of the homeotic and segmentation genes.

HOM-C基因在决定前-后轴的性质方面有什么基本功能呢？

The term"homeodomain"has evolved to define a class of protein domains that has recognizable similarity to a 60 amino acid motif (encoded by 180 bp homeobox sequences) originally recognized in three Drosophila homeotic and segmentation proteins. The homeodomains that have been tested contain sequence-specific DNA binding activities and are part of larger proteins that function as transcriptional regulators.

其中一类转录因子通过同源域结合特定的DNA序列，这种特殊的转录因子都包含一个同源盒，它有180bp序列可以编码DNA结合同源域，称同源盒基因（Homeobox gene，Hox gene），带有同源框的基因经过转录产生带有同源域的蛋白质。

Based on the demand for image enhancement in corner extraction of image segmentation,this paper researches homomorphic filtering technique.

1概述图像增强是图像预处理中提高视觉效果的重要手段，包括去除噪声、扩展对比度等。

The commonly used cluster based segmentation method assumes that the sample distribution is hyperspherical, but this kind of assumption is not consistent with the real characteristic of the human brain MR image.

通常使用的聚类分割方法认为样本的分布是超球形的，然而，这并不符合人脑磁共振MR（magnet－icresonance）图象的真正特点。

Rifling-treating is a key technique because rough rifling adds difficulty to image processing. So the rifling-treating uses the method of area gray-scale average, which makes up the incontinuity of image. Image segmentation aims to separate the defects from the background.

膛线的处理是火炮内膛缺陷处理的关键之一，它的凹凸不平给图像处理带来极大的困难，采用区域灰度值平均法，较好的克服了图像的不连续性。

To decrease extraction errors made by image noise and natural boundary incontinuity,authors make an accurate multi-segmentation with Bayes classification technique to revise the result.

纹理合成技术应用广泛，一个成功的纹理合成算法可以应用在图像缺失信息填补、图像、视频压缩、背景移除、真实感造型等领域。

An important step is how to extract and segment the information of defects from inspective image.This paper introduces a digital subtraction into image segmentation in order to make the algorithm simpler,more automatic,high-speed,and accurate.

引言随着生产技术的发展，现代工业对于X射线的自动检测与识别的需求越来越迫切，而要实现它的关键是如何将缺陷及反映缺陷特征的信息从图像中提取出来，并给予正确的解释。

On the basis of K-means clustering segmentation and region connection,the edges of the target and backgrounds were extracted accurately and intactly.

将K-均值聚类方法与分形理论相结合，提出了一种分两个阶段对扩展目标进行分割的方法。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
