In the below example we find the contours present in an image files. Cropping an Image using OpenCV - LearnOpenCV Extracting Regions of Interest from Images using OpenCV and Python - debalb Python OpenCV - Find center of contour - GeeksforGeeks Write Text at the center of the image using Python cv2.puttext. This is because OpenCV reads the image in Blue Green Red colours and to view the actual image we need to convert to Red Green Blue using the method cv2.CvtColor). If you know the shape (width, height) of the text you write on the image, you can put it in the center aligned on the image. Read the image using opencv, which returns the Image ndarray. To access pixel data in Python image, use numpy and opencv-python library. Image Segmentation using K-means. Feature Based Image Alignment using OpenCV (C++/Python) Or even to highlight a particular feature of an image. Let's now go over this code. The central_fraction param is set to 0.7. cropped_img = tf.image.central_crop(img, central_fraction=0.7) Here is the full code and the cropped image shown below: OpenCV: Drawing Functions in OpenCV The 3 integers represent the intensity of red, green, blue in the same order. Best features to track fish underwater. Detecting multiple bright spots in an image with Python and OpenCV How to Access Pixel Data in Image using Python OpenCV The imread () Method takes two parameters. OpenCV provides a builtin function for finding the convex hull of a point set as shown below. In the below example we will take an image as input. where window_name is the title of the window in which the image numpy.ndarray . Draw Contours on an Image using OpenCV - Medium
