查询词典 pixel

Whole image is seen as a discrete random field, each pixel is a random variable.

整幅图像被看作是一个离散的随机场，每个像素都是一个随机变量。

Vexel art is a digital art that is an entirely pixel-based form of raster art that imitates the vector graphics technique, but is distinguished from normal vector graphics or raster images.

Vexel art是一种数字艺术，完全是基于像素的光栅艺术形式，模仿矢量图形技术，但正常的矢量图形和光栅图像是有区别的。

In order to improve the effect of image and the exactitude of vectorization, this dissertation supplies raster image edition and vector graphics edition, which can make pixel operation and amend image vectorization results. At the same time it supplies the image transform to the form of CAD and can be edited and modified in the condition of CAD.This dissertation has just carried on the simple try in the Engineering drawing ectorization respect, too.

为了进一步提高图像处理的效果和矢量化的准确度，本文在图像处理阶段和自动矢量化后阶段均提供了简单的编辑功能，既可以对图像进行像素级操作，也可以对矢量化过程中产生的失真现象进行修正；同时给出矢量化数据到CAD软件的图形格式转换接口，从而有利于和CAD环境的无缝联接。

The purpose of this thesis is to design a CMOS Image Sensor which can reduce the area of post-processing buffer memory, caused by pixel output order of raster scan and processing sequence of block-based image processing system does not match, to reduce cost and power consumption.

本论文的目的是设计一局部扫瞄式影像感测晶片，此晶片可以节省因为光栅式扫瞄的像素输出顺序与区块化影像处理系统的处理顺序不匹配而造成的后处理缓冲记忆体面积，以达到减少成本开销与降低功率消耗。

In general,these types of images contain both header information and the raw pixel data.

通常，这些类型的图像包含头信息和原始像素数据。

For any image processing task, one needs to access raw pixel data.

在任意的图像处理任务中，都需要访问原始的像素数据。

The SNR of brain white matter and the background standard deviation were measured within ROI,which cov ered a large homogeneous area of white matter.The mean pixel values were recorde d within the ROI which was positioned of the head of the femur.

设定兴趣区，并测定脑白质均匀区域的信噪比及背景的标准差，以及以盆腔股骨头为ROI，记录ROI的平均值，交替测量肌肉区域的平均值及背景的标准差。

Edge filling algorithm demo, will be designated irregular region pixel fill color for the fill in the computer-aided design and image processing and other fields have wide application.

详细说明：边填充算法的演示，将指定不规则区域内部像素填充为填充色，在计算机辅助设计和图像处理等领域有广泛应用。

For getting the major characteristic edges without confusions by undesired structures like muscle edges, we integrate a star-like edge detection filter named "Asterisk Filter" with the Canny Edge Detection in the image preprocessing. In addition, we also propose a new contour tracking method named "One-Pixel Rolling Ball Contour Tracking" for getting the boundary information in a binary image which is a link-list data structure. Instead of using a regression curvature estimator, PCA is used for better curvature estimation from a discrete bony contour.

为了从影像上取得骨头特徵边缘，将不重要的肌肉视为杂讯滤除，我们引用一种星形滤波器－Asterisk Filter，搭配Canny边缘检测法，做为这类影像的前处理；另外，为了将骨头的边缘精确地追踪出来，我们提出滚球边界追踪法，来对二值化影像进行边缘追踪，藉此获得边缘的串列资料结构；我们采用以主成分分析(Principle Component Analysis，简称PCA)取代原本以回归方法来计算的曲率，以取得更佳的曲率估测值，其可提高计算之参数的准确性。

One modified active pixel sensor contains several pasts: photo-input, smoothing network, reset switch, source follower.

一个改良后的主动式画素感测单元包含几个部份：光输入元件、平滑网路、重置开关、源极追随器。

I had a lovely dog named PiPi, he was one of my best friends.

我曾经有过一只小狗，它的名字叫皮皮，它很善良，它是我最忠实的朋友。

Newly ovulated mouse oocytes were cultured in the CZB medium supplemented with different concentrations of pyruvate before treated for activation or assayed for MPF activity.

我们猜测卵母细胞在不含丙酮酸的条件下老化的更快，并且卵丘细胞可能通过消耗不含葡萄糖的CZB中的丙酮酸从而促进卵母细胞老化。
