Opencv 이미지 이진화

I will use the OpenCV library and C++, but you can easily follow along with any of the other OpenCV bindings (C, Python, Java). Lets start by thresholding the input image for anything that is not red But OpenCV comes with a caveat - it can be a little tough to navigate for newcomers. There are a plethora of functions available inside OpenCV, but it can become daunting t In this tutorial we will check how to flip an image, using Python and OpenCV. We will flip the image across the x-axis, the y-axis and then across both axes. Introduction OpenCV 실전. 이미지 읽기, 쓰기 및 표시하기. 이미지 위에 도형 그리기.

지금까지 thresholding처리를 하면서 임계값을 사용자가 결정하여 parameter로 전달하였습니다. 그렇다면 그 임계값을 어떻게 정의해야 할까요? 가장 일반적인 방법은 trial and error방식으로 결정했습니다. 그러나 bimodal image (히스토그램으로 분석하면 2개의 peak가 있는 이미지)의 경우는 히스토그램에서 임계값을 어느정도 정확히 계산 할 수 있습니다. Otsu의 이진화(Otsu’s Binarization)란 bimodal image에서 임계값을 자동으로 계산해주는 것을 말합니다.
