nurbs曲线

灰度图像直方图的计算，超级好用的啊，可以通过它获得图像的分形维数等等，内存小，功能大(Gray image histogram calculation, super nice ah, you can get through it the fractal dimension of the image, and so on, the memory is small, functional large)

抗任意角度旋转的图像匹配算法的matlab实现(image matching of any rotation )

说明：  声呐或者雷达系统发射信号后，通过波束形成算法对两个目标（方位分别为theta1、theta2）回波进行仿真，经过相位补偿，可以看出图像有两个波峰，波峰处指向性函数峰值最大，峰值所对应的的角度值即为目标的方位角。所以该程序对数字波束形成（DBF）的原理进行了仿真，适合初学者掌握阵列信号处理中数字波束形成的原理。(After the sonar or radar system transmits the signal, the echo of the two targets (the azimuth is theta1 and theta2 respectively) is simulated by the beamforming algorithm. After the phase compensation, it can be seen that the image has two peaks, the peak of the directivity function is the largest, and the corresponding angle value of the peak is the azimuth of the target. So the program simulates the principle of DBF, which is suitable for beginners to master the principle of DBF in array signal processing.)

图像保重要特征扩散滤波方法之-----非线性扩散(important feature images Bao proliferation filtering method----- Nonlinear Diffusion)

质心定位算法，代码在matlab2013b下调试通过，希望对下载君有所帮助。(Centroid positioning algorithm, the code in matlab2013b debugging through, and I hope to download Jun help.)

图形学中的透视投影算法 在屏幕中心绘制立方体的透视投影 可以绘制一点透视图 二点透视图 三点透视图(Graphics in the perspective projection algorithm for drawing a cube in the center of the screen you can draw a little perspective projection perspective two point perspective three-point perspective)

六次迭代使三角形三条线分形折叠，最后组成雪花(Six iterations make triangles become snow)

说明：  绘制二维nurbs曲线，可以通过改变控制点或者权重从而改变图形的形状。(Draw a two-dimensional nurbs curve that changes the shape of a shape by changing the control point or weight.)

三视图，用二维图像显示三位图像，分主视图，俯视图，侧视图(view)

说明：  在大图中寻找到小图。 并圈出小图所在位置。 图片用picture控件显示。(In the big picture to find a small map. )
