像素比

对分割后的图像，本文采用黑白像素比（BWR）及黑白像素交替变换数（CC）两个特征进行进一步的分类。

To classify different segmented regions as text regions or non-text regions , two features of the black to white pixel ratio ( BWR ) and the cross-count ( CC ) of pixels were used for the classifications .

利用该模型分析了LCoS与CMOS阵列像素数比、像素开口率、相对平移、相对旋转等因素对系统互信息量的影响。

According to the model , the factors that affect the mutual information are analyzed , such as the ratio of LCoS pixel number to CMOS pixel number , aperture ratio of LCoS and CMOS pixel , relative displacement and relative rotation angle .

我们将像素色度比向量向光照无关方向投影获取光照无关图，利用线性色彩恢复机制得到具有良好色彩表现的无阴影彩色图像。

We project band-ratio vectors of image pixels onto illumination-invariant direction to obtain illumination-invariant grayscale image , then employ a linear color restoration mechanism to acquire shadow-free color image .

由于光谱估计算法需要采集每一个像素的光谱反射比，多通道成像系统需要采集和存贮比三通道的RGB系统多得多的数据。

Because the spectrum estimation arithmetic needs to capture the spectrum reflectance of each pixel , the multi-spectral imaging system needs to capture and store more data than the three-channel RGB system .

比混合色亮的像素被替换，比混合色暗的像素保持不变。

Pixels lighter than the blend color are replaced , and pixels darker than the blend color do not change .

以区域变化点的数量和该区域像素总数量的比作为比较值，设定阈值，确定运动区域。

Changes points divided by the total number of pixels in the region as a comparative value . The comparative value compared with a threshold to determine the motion regions .

扫描仪误差包括像素间距误差、像素间距横纵比误差及扫描起点误差等。

Scanner errors include pixel interval error , horizontal-to-vertical proportion error and starting position error .

给你带来这种发现的技术在今年正奋力成为主流：超高清电视，其像素是行业标准高清电视的四倍。其像素比一些电影放映机还多，像素密度之高，人眼已无法分辨单个像素。

It 's the kind of discovery you can make with a technology that 's pushing for the mainstream this year : televisions that have four times as many pixels as the industry-standard high definition . That 's more pixels than some cinema projectors , packed in so tight they just melt away .

纹理密度是描述如何密集的像素映射到阁下的三维模型表面的一个像素长度比单位。

Texel Density is a unit and pixel length ratio that describes how dense pixels are mapped on the surface of your3d model .

在亚像素细分算法部分，对比了几种常见的亚像素细分算法之后，本文采用了一种最为有效的细分算法，试验表明亚像素级数据比像素级数据精度大大提高。

In the section of the sub-pixel subdivision method , we introduced several common sub-pixel subdivision methods and then adopted a simple and effective method according to the request of precision and the condition of the experiment .
