旋转矩形,center是矩形的两条对角线的交点,size.width和size.height分别是矩形的宽和高,angle是旋转角度,所以这个矩形是可以倾斜的,于是我们可以发现up-right retangle其实就是矩形的边平行x轴和y轴的的情况。 关于angle这个参数在我的另一篇博客里细讲 opencv2.0 DataType 实现 ,在1.0版本中对应了Cvbox2D这个结构...
3.4 Adjustable Rotated Weight Vector 使用旋转矩阵对权重向量进行旋转调整后可以缩小权重向量二值化前后的角度偏差,我们可以令旋转后的权重向量为 ~wi=(Ri)Twi ,接着会使用 sign 函数进行二值化,然后进行标准的梯度更新。不过,由于我们采用的是交替更新的策略,在更新的过程中很可能会陷入一个局部最优解,其在几何...

R = rotate_3D(V, mode, theta, u) computes the vector R, which results from the rotation of V vector around u vector and of theta angle in radian. R = rotate_3D(V, mode, theta, u, angle_unit) uses angle_unit for theta unit (radian or degree). [R,Rm] = rotate_3D(V, mode,...
