Contour properties opencv. (NB : Centroid, Area, Perimeter etc also belong to this category, but we have seen it in last chapter) Mar 2, 2026 · Prev Tutorial: Contours : Getting Started Next Tutorial: Contour Properties Goal In this article, we will learn To find the different features of contours, like area, perimeter, centroid, bounding box etc You will see plenty of functions related to contours. It is the ratio of width to height of bounding rect of the object. \[Equivalent \; Diameter = \sqrt{\frac{4 \times Contour \; Area}{\pi}}\] Here, two methods, one using Numpy functions, next one using OpenCV function (last commented line) are given to do the same. Results are also same, but with a slight difference. Sep 19, 2022 · A notebook containing handy tools for working with contours in OpenCV. Contours : More Functions Jan 8, 2013 · Prev Tutorial: Contours : Getting Started Next Tutorial: Contour Properties Goal In this article, we will learn To find the different features of contours, like area, perimeter, centroid, bounding box etc You will see plenty of functions related to contours. We use OpenCV's findContours () function that works best for binary images. Contours : More Functions Jul 4, 2025 · Contours are edges or outline of a objects in a image and is used in image processing to identify shapes, detect objects or measure their size. OpenCV (Open Source Computer Vision Library) is a popular open-source computer vision and machine learning software library. Mar 2, 2026 · Contour Properties Prev Tutorial: Contour Features Next Tutorial: Contours : More Functions Here we will learn to extract some frequently used properties of objects like Solidity, Equivalent Diameter, Mask image, Mean Intensity etc. hossrdkmmavwqstddpnyydcgyjiysfjueshhnllmhtapbekjfnjuhrd
