计算机图形学中的裁剪算法。裁剪的用途是从一幅大的画面中提取所需的信息。...

canny检测器是很有效的边缘检测器，该函数可以实现对目标图像的边缘提取。该方法总结如下：1.图像使用带有指定标准差的高斯滤波器来平滑，以此减少噪声；2.在每一点计算局部梯度和边缘方向；3.第二步中确定的边缘点会导致梯度幅度图像中出现脊，然后追踪所有脊的顶部，并将所有不再脊顶部的像素设置为0；4.执行边缘链接-canny detector is very effective edge detector, this function can be achieved on the target image edge detection. This method is summarized as follows: 1. Image used with the specified standard deviation of the Gaussian filter to smooth out, thereby reducing the noise 2. In the calculation of each point of local gradient and edge direction 3. The second step in determining the edge points will led to the image gradient magnitude ridge appears, and then keep track of all of the top of the ridge, and ridge at the top of all the pixels are no longer set to 0 4. the implementation of the edge link

利用线性神经网络进行自适应预测 利用函数adapt对线性网络进行自适应训练，在线修正网络的权值和阈值，这样对于时变信号，网络就可以及时跟踪其变化，即可对时变信号序列进行预测。 -linear adaptive neural network prediction using linear function adapt to the network adaptive training , the online network that the weights and thresholds, so for the time-varying signal, the network can track changes in a timely manner. will be the time-varying signal sequence forecast.

本代码是一个在c#环境中使用emgucv（opencv）库进行人脸识别的程序，非常简单。很适合入门者来学习，非常感谢原作者的辛苦劳动。 opencv本身是使用c++开发的，emgucv是对opencv的封装，可以在c#环境汇总直接使用。
