Number Plate Detection Image At first, Go to Teachable Machine and Choose a new Image… hello, i need a tool which detect floor and replace it with a sample. In all these cases, the first thing we have to do is extract the people or vehicles that are at the scene. approach: camera detect all people near to the car, and by running algo like HOG or CNN software can detect normal and abnormal behavior ,and if it's abnormal behavior the prog sends alaram to the car owner. Reading images with OpenCV Detecting Circles With OpenCV and Python: Inspiration :-The Idea for this came when I was tinkering with OpenCV and it's various functions. For example, when we want to count the people who pass by a certain place or how many cars have passed through a toll. OpenCV is released under a BSD license and hence it’s free for both academic and commercial use. Originally written in C/C++, it now provides bindings for Python. However, face detection can have very useful applications. Let’s take two images a not blurry one and a blurry one: NOT BLURRY; BLURRY ; What is a blurry image?
