[Special Effects] Mark-a-watershed-segmentation DL : 0: 分五个部分讲解：1.计算分割函数。图像中较暗的区域是要分割的对象。 2.计算前景标志。这些是每个对象内部连接的斑点像素。 3.计算背景标志。这些是不属于任何对象的像素。 4.修改分割函数，使其仅在前景和后景标记位置有极小值。 5.对修改后的分割函数做分水岭变换计算。-Divided into five sections explain: (1) Calculate the partition function. The dark areas in the image is the object you want to split. (2) Calculate the prospect signs. These are spots connected pixels within each object. (3) calculate the background logo. These pixels do not belong to any object. (4) Modify the partition function, making only the minimum marker position in the foreground and a rear view. 5 watershed transform the modified partition function calculation.

[Special Effects] Edge-Detection DL : 0: An Augmented Reality app that demonstrates basic computer vision concepts such as greyscaling, thresholding, edge detection, homography, corner detection...its a long list. It paints a 3D image on any detected markers. Here is a crude video that shows the application in action. Here is a marker with the a 3D object (the CNU logo) rendered correctly on its surface plane. Beside it is the marker with no image.
