查询词典 pixels

The main characteristics and contributions of the dissertation can be summarized as follows: Currently, all the background modeling algorithms classify foreground from background based on pixels but not the structure information of an object, which leads to fragmentized foreground or introduces too much redundant foreground.

在实际的应用中，如何定义目标物以及何时对目标物进行跟踪是两个重要的问题，本文通过形态学和连通性分析等操作把获取的前景区域分类成若个Blob，每个Blob对应一个目标物；本文还为每个Blob维护了一个跟踪列表来确保传递给系统跟踪模块的Blob是稳定的，可信的目标物。

For the same reason, the illuminated parts of the pixels are smaller and further apart than they could be, so the image is fuzzier.

基于同样一个原因，像素被照亮的部分就变得比本来面目更小并越加分离，因此图像也就变得模糊不清。

The theoretical framework of the CCS-based steganographic scheme is given, in which pixels are divided into groups and secret data are embedded into each group. The proposed scheme guaranties that the pixel value changes at most one in the embedding process.

建立了基于完全覆盖集的隐写方法的理论框架，使用将像素点分组的方式对每组像素点来嵌入信息，同时保证了在嵌入过程中每点像素值最多改变1。

Light, represented by the rainbow at the top of the image, impinges on photodiodes with the CCD pixels.

在图象顶部以彩虹代表的光，与CCD像素的发电二极管紧密接触。

Re-vectorization is performed on the basis of original vectorization by obtaining the initial parameters such as line types and slope. Inuring tricing it can adjustthe parameter adaptively. To decrease the influence of noise pixels, we designed a stop probe to detect tracing-stop conditions. Process of re-vectorization is performed recursively until quality of graph entity is satisfactory.Finally, some key technologies for 2D graphs reconstruction are studied. The issues concerned include the recognition and presentation of topologic relations among graphs entities and a directed and weighted graph model established to describe the relations and techniques on dimension driven.

在获得对图素识别质量的评价之后，质量较差的图素被输入到错误自动校正器进行错误校正处理，本文提出&二次矢量化&的错误校正思想，二次矢量化是在初步矢量化所获得知识的基础之上，取得初始参数，并在跟踪过程中动态校正参数，在跟踪结束时引入跟踪终止检测探针以消除光栅图像中黑白噪音的影响，使得算法具有较强的抗噪音干扰能力，校正后的图素仍需进行质量评价，未能通过评价的图素需递归执行二次矢量化算法。

But if you use a larger bucket, more light is properly stored in the pixels, without spilling.

但是如果你拥有一个大桶，更多的光线就会被记录在一个象素上，而不会产生溢出。

After registration,two images are mosaicked by using a weighted sum of two corresponding pixels.

在两张图像进行匹配校正之后，镶嵌过程可以通过相应点颜色值的带权求和予以实现。

Saturation occurs then pixels in bright areas are overexposed causing them to turn completely white.

发生色饱和后，像素在明亮区域感光过度使其出现完全一片白色。

The image watermarking is permuted to reduce the relativity of original pixels, so the error bits of the extracted watermarking are dispersed as well. Therefore the resistance to crop attack is improved significantly.

对数字水印信号进行置乱分散了原始水印信号的相关性，在遭到剪切攻击时可以将错误码元尽可能分散，因此有效地提高了数字水印算法的抗剪切攻击性能。

对数字水印信号进行置乱分散了原始水印信号的相关性，在遭到剪切攻击时可以将错误码元尽可能分散，因此有效地提高了数字水印算法的抗剪切攻击性能。

Objective:To compare the response control and attention of Schizophrenic patients with that of the healthy controls by Integrated Visual and Auditorycontinuous performance test. To quantitate the impairment of cognitive function in patients, and to explore the relationship between cognitive function and the severity of the disorder.

目的：探讨精神分裂症病人在IVA持续操作测试中的反应控制能力、注意力等，并与健康人进行比较，从而量化精神分裂症病人的认知功能损害，并进一步探讨其认知功能与疾病严重程度的关系。

Main effective factors including subcooling degree, mechanical vibration, gas hydrate reformation, environment temperature, noncondensing gas and surfactant are analyzed.

指出过冷度、机械振动、重复生成水合物、环境温度、不凝性气体、添加剂是影响气体水合物生成的主要因素，还对R152a水合物的放冷进行了实验研究。
