. The function cv::rotate rotates the array in one of three different ways: . * Rotate by 90 degrees clockwise (rotateCode = ROTATE_90_CLOCKWISE). . * Rotate by 180 degrees clockwise (rotateCode = ROTATE_180). . * Rotate by 270 degrees clockwise (rotateCode = ROTATE_90_COUNTERCLOCKW...
You are given annxn2D matrix representing an image. Rotate the image by 90 degrees (clockwise). Follow up: Could you do this in-place? 解题思路1:先将矩阵转置,然后将矩阵的每一行翻转,就可以得到所要求的矩阵了。为便于理解,制作了如下示意图. Figure 1: Illustration of transpose operation. Only ...

ImageProcessor+load_image(path: str)+rotate_image(degrees: int)+show_image()+save_image(path: str) 结论 通过上述步骤,我们成功使用Python的NumPy和Matplotlib库实现了图像旋转90度的功能。首先是导入所需的库,其次是读取图像,并转换为NumPy数组,然后旋转图像,最后显示或保存结果。这个过程清晰而简单,适合初学...
image = cv2.imread('path/to/your/image.jpg') 使用OpenCV的旋转函数对图像进行90度旋转: OpenCV提供了cv2.rotate()函数,可以方便地实现图像的旋转。为了顺时针旋转90度,可以使用cv2.ROTATE_90_CLOCKWISE作为旋转参数;为了逆时针旋转90度,可以使用cv2.ROTATE_90_COUNTERCLOCKWISE作为旋转参数。 python # 顺时针旋转...
48. Rotate Image python You are given an n x n 2D matrix representing an image. Rotate the image by 90 degrees (clockwise). Note: You have to rotate the image in-place, which means you have to modify the input 2D matrix directly. DO NOT allocate another 2D matrix and do the ...
img = Image.open('geek.jpg') # rotate by 90 degrees rot_img = img.transpose(Image.ROTATE_90) rot_img.show() 输出: 旋转180 度:要旋转 180 度,使用的关键字是 Image.ROTATE_180 语法: img.transpose(Image.ROTATE_180) 例子: Python实现 from PIL import Image img = Image.open('geek.jpg')...
Rotate an array by 90 degrees in the plane specified by axes. Rotation direction is from the first towards the second axis. k: Number of times the array is rotated by 90 degrees. 关键参数k表示旋转90度的倍数,k的取值一般为1、2、3,分别表示旋转90度、180度、270度;k也可以取负数,-1、-2...
