在计算机视觉中,图像分割是将图像分成多个片段的过程。这使我们能够通过以比原始图像更简单的表示方式来更好地分析图像。一种用于分割图像的方法是阈值分割;也就是说,将强度值低于阈值的所有像素设置为背景值,而将高于阈值的其他像素设置为前景值。最简单的阈值处理形式是对所有像素使用全局阈值,而自适应阈值处理根据像素及其周围环境动态改变阈值。典型地,阈值处理从灰度图像开始,并输出二进制图像以清晰地描绘图像中的片段。在本实验中,我们开发了一种自适应阈值算法,并将其与更简单的算法进行了比较。 此外,我们还开发了逆运动学证明来将机械臂移动到给定的x,y,z坐标。这一证明涉及三种命名身份,并获得了对机械臂设计的更好理解。(Image threshold segmentation)

FAST-ICA
1、对观测数据进行中心化,;
2、使它的均值为0,对数据进行白化—>Z;
3、选择需要估计的分量的个数m,设置迭代次数p<-1
4、选择一个初始权矢量(随机的W,使其维数为Z的行向量个数);
5、利用迭代W(i,p)=mean(z(i,:).*(tanh((temp) *z)))-(mean(1-(tanh((temp)) *z).^2)).*temp(i,1)来学习W (这个公式是用来逼近负熵的)
6、用对称正交法处理下W
7、归一化W(:,p)=W(:,p)/norm(W(:,p))
8、若W不收敛,返回第5步
9、令p=p+1,若p小于等于m,返回第4步
剩下的应该都能看懂了
基本就是基于负熵最大的快速独立分量分析算法(1, on the center of the observation data, 2, making a mean of 0, the data to whitening-> Z 3, select the number of components to be estimated m, setting the number of iterations p < -1 4, select an initial weight vector (random W, so that the Z dimension of the row vectors of numbers) 5, the use of iteration W (i, p) = mean (z (i, :).* (tanh ((temp) ' * z)))- (mean (1- (tanh ((temp)) ' * z). ^ 2)).* temp (i, 1) to learn W (This formula is used to approximate the negative entropy) 6 with symmetric orthogonal treatments W 7, normalized W (:, p) = W (:, p)/norm (W (:, p)) 8, if W does not converge, return to step 5 9 , so that p = p+1, if p less than or equal m, return to step 4 should be able to read the rest of the basic is based on negative entropy of the largest fast independent component analysis algorithm)
