The rotate function provides the option of rotating the image in three ways. Approach Instead of directly writing the rotated text, we can first write the text at the desired location and then rotate it. Take a look at the function introduction. You will also learn some of the intermediate level topics like finding contours in the image, capturing video from camera, blending images, writing text on the image, etc. cv2.flip (src, flipCode [, dst]) dst. The cv2.getRotationMatrix2D function takes three arguments. 1. image=cv2.imread('boat.jpg',1) 2. height,width,channel=image.shape. cv2.imshow("Image", image) First, we will instruct OpenCV to go and find the image "lucid.jpg", read it, and then store it in this variable "image". python by Different Dove on Aug 04 2021 Comment .

We then specify , the number of (counterclockwise) degrees by which we will rotate the image. def _append_brightness_adjusts (self, path, angle, flip, brightness_adjusts = [1.0]): """ Specifies what the needed brightness adjusts for a specific image are and appends them to X/y_train Parameters-----path : string The path to the image angle : float Steering angle flip : boolean Should we flip the image when reading the list brightness_adjusts: list List of floats specifying what . If OpenCV is not installed in your system then first install it using This Method. Horizontal Flip Vertical Flip. Syntax: cv2.cv.rotate ( src, rotateCode [, dst] ) Parameters: src: It is the image whose color space is to be . Let us see how each function works in detail.
