The Contour filtering system provides a gentle perturbation of the IF filter passband.
轮廓过滤系统提供了一个温和的摄动的IF滤波器通。
Aim at some discrete points after contour extraction subtracting contour tracing, a special filter is designed to eliminate these discrete points, and at the same time to keep the continuous contour.
针对轮廓提取减去轮廓跟踪后的图像出现的离散点，提出了一种专门的滤波方法，消除离散点，保证图像轮廓的连续。
In tracking, the area of face contour distortion were searched by the method of particle filter, and the face contour parameters were solved.
同时，利用非线性滤波方法在人脸轮廓的变形区域内进行搜索，求解人脸轮廓参数，进行人脸轮廓跟踪。
During contour evolution, the particle filter (PF) is used to track the feature points by enforcing spatiotemporal local constraints to handle the observation noise.
为避免观测噪声的影响，增加轮廓的时空局部约束并利用粒子滤波(PF)技术解决该类跟踪问题是非常有效的。
And they are often distorted. First, a low passed filter is used to smooth the contour. And a polygon approximating method based on area error is used to approximate the contour.
鉴于这种情况，我们先使用低通滤波对轮廓曲线作光顺处理，随后再采用基于面积误差的多边形逼近法对曲线作逼近处理。
Properly shifting the filter on the frequency region can improve the contrast and the contour acuity of the output image. It is profitable for edge detection.
阶跃滤波器在频域的适当的位移(偏置)即可以改善输出图像的衬底，也能改善其轮廓视锐度，从而有利于图像边缘的检测。
