pixel

at this magnification the pixels making up the image become visible.

通过这种程度的放大组成图像的像素就看得见了。

The algorithm in the proposed program can mask the image data and permute pixels location by chaotic sequences.

算法程序首次采用了图像数据的混沌掩盖加密和图像象素位置的置乱加密相结合的方法,对图像进行了两次复合的混沌加密。

Then, noise decorrelation, baseline decorrelation and pixel misregistration decorrelation and so on, are analyzed, and the image correlation coefficient is deduced.

理论分析了相关、图像配准误差相关、热噪声相关等，并推导了图像相关系数；

degree of unbalancedness S of distribution of moment of force on the periphery of the unit circle is calculated, and the force is corresponding to the component of the pixel-dot vector;

计算所述像素点矢量的分量对应的力的力矩在单位圆圆周上分布的不平衡度S；
