I have a large number of aerial images. Some of them have the lens partially occluded. For example: and I'm trying to automatically detect which of the images have this using OpenCV. My initi...

How can I check if a vertex in a model can be seen by a camera or if it's hidden behind another object? I aim to use that information to find the coordinates and size of a bounding box that would ...

So to be clear on my goals, since I don't have any code to share... Lets say I have a SCNNode which is positioned between the camera and another SCNNode. The first SCNNode is a SCNBox, but ha...

I'm trying make virtual objects be hidden when a real world object is positioned in front of it, but not having any luck with it, i've been playing with the occlusion settings in unity but the virt...

I am trying to implement a people counting system using computer vision for uni project. Currently, my method is: Background subtraction using MOG2 Morphological filter to remove noise Track blob...

What am I doing wrong here please? I'm trying to shade alternate 24-hr daily rectangles with transparent gray. But only the last rectangle from the for-loop gets drawn(?!?) If I do things manually ...

In my 2D game, I have static and dynamic objects. There can be multiple cameras. My problem: Determine objects that intersect with the current camera's view rectangle. Currently, I simply iterate ...

I'm writing a Minecraft like static 3d block world in C++ / openGL. I'm working at improving framerates, and so far I've implemented frustum culling using an octree. This helps, but I'm still seein...

What is the most efficient way to identify the vertices that are visible from a particular viewpoint? I have a scene composed of several 3D models. I want to attach an identifier to each vertex (M...

The occlusion algorithm is necessary in CAD and game industry. And they are different in the two industries I think. My questions are: What kind of occlusion algorithms are applied respectively i...
