The asymptotic estimates of the descriptor system state and the output noise are obtained at the same time.
使用该观测器可以同时得到系统状态和输出噪声的渐近估计。
A novel image texture feature descriptor is proposed which is insensitive to Gaussian blur and Gaussian noise.
提出了一种对高斯模糊和高斯噪声鲁棒的图像纹理特征描述算子。
After that, the new idea of average moments of these feature points is proposed. This feature descriptor has good robustness and is not so sensitive to noise and the delicate changes in image's edges.
然后提出了基于多特征点平均矩特征的概念，该特征不仅具有良好的鲁棒性，而且对于噪声以及图像边缘的细微变化并不敏感，非常适合用来描述商标这种特定的图像。
