Detecting car's windshield and rear window - OpenCV Q&A …

· Hi I'm working on a car occupant counter system that must count occupant of cars in a video stream (see attached image). I read some related papers and found that in all models they firstly define tow ROIs by detecting the windshield and rear window, then look up for an occupant in these ROIs. I have searched for different object detectors in OpenCV and found two implemented object …

opencv - How can HOG be used to detect individual body ...

I would like to use OpenCV's HOG detection to identify objects that can be seen in a variety of orientations. The only problem is, I can't seem to find a reasonable feature detector or classifier to detect this in a rotation and scale invaraint way (as is needed by objects such as forearms). Prior Work: Lets focus on forearms for this ...

Detecting object regions in image opencv - Stack Overflow

· Finally, given that you have a stable background with clear objects in view, I would take a look at Bag-of-Features to see if you can just detect each individual object in the image. This may be useful since there seems to be a consistent pattern to the objects in these images. You can build a big database of images such as needles, gauze, scissors, etc. Then BoF, which is in OpenCV will find ...

OpenCV-object-detection-tutorial by JohnAllen

Here's a great example of how well OpenCV's object detection can work when you get it right!! In this post, I use *nix programs; I apologize to Windows users in advance. I want to point out that installing OpenCV for certain platforms can be complicated and slow. I suggest reading this post thoroughly, collect your images and then install OpenCV on a remote server. Installation will be much ...

c++ - How can I detect TV Screen from an Image with OpenCV ...

· If you can properly segment the image via foreground and background, then you can easily set a bounding box around the foreground. Graph cuts are very powerful methods of segmenting images. It appears that OpenCV provides easy to use implementations for it. So, for example, you provide some brush strokes which cover "foreground" and "background" pixels, and your image is converted into a ...
