[OpenCV] 4 DL : 0: 看到有的网站搞分形艺术，才知道这个Z=Z*Z+C 如此的奇妙。于是干脆在opencv下写出来，看看。效果还不错。呵呵。这个小例子只能修改C的值，有兴趣的朋友可以自己改改代码，看能不能做出些美妙的图形。代码提示：要获得高质量的图像，可以增加image_w，不过性能很低。-See some sites do fractal art, to know that Z = Z* Z+ C so wonderful. So they simply write under the opencv to see. Results were pretty good. Oh. This small example can only modify the value of C, interested friends can change to change their own code, see if I can make some wonderful graphics. Code Tip: To obtain high-quality images can increase image_w, but the performance is very low.

[OpenCV] 3 DL : 0: 输入：自拍两幅同一个场景(或物体)的角度/远近有差别的图像（对于学有余力的同学，建议多测试几张角度/远近差别较大的图像）任务：在每张图像中检测特征点位置并将匹配画出匹配得最好的10-20对特征点输出要求（以下三个结果分别输出，不要重叠在一张图上）： 1. 在两张图上分别画出检测到的特征点位置 2. 对匹配得最好的10-20对特征点：每对特征点对用连接线画出 3. 用椭圆形式在图上画出上述每个特征点的描述子方向与尺度等信息编程工具： Visual C++/Visual Studio，OpenCV 提示-Input: self-timer two same scene (or object) angle/distance difference image (For students there is spare capacity, the proposed multi-test a few angle/distance difference larger image) task: each image detection the location of the feature points and match draw match best 10-20 on the output requirements of feature points (three results output, do not overlap in a diagram): 1. draw detected respectively in the two graphs the orientation and scale of the feature point position 2 of the best match 10-20 to feature points: each pair of feature points to draw the connecting lines 3. using elliptic form shown in diagram of each of said feature point descriptor and other information programming tools: Visual C++/Visual Studio, OpenCV Tip
