在本节中,我们将演示如何使用 scikit image 的形态学模块中的函数来实现一些形态学操作,首先对二值图像进行形态学操作,然后对灰度图像进行形态学操作。 二进制运算 让我们从二值图像的形态学操作开始。在调用函数之前,我们需要创建一个二进制输入图像(例如,使用具有固定阈值的简单阈值)。 腐蚀 侵蚀是一种基本的形态...
如果用户不提供平铺图像,就利用createRandomTile()方法,用随机圆圈创建一张平铺图像。 # create an image tile filled with random circles def createRandomTile(dims): # create image ❶ img = Image.new('RGB', dims) ❷ draw = ImageDraw.Draw(img) ...
image = cv2.imread("image/test.jpeg") cv2.imshow("window", image) 1. 2. 3. 4. 因为程序一旦停止运行,图片就不会展示了,所以会出现一闪而过的窗口展示,所以为了让图片长时间展示出来,那么需要加:cv2.waitKey() cv库中的函数cv.image读取的是图片的像素矩阵,矩阵单元是rbg的向量形式。下面举例读取纯色...

Too Long; Didn't ReadUse PIL the following way to create a pixelated Image: from PIL import Image image = Image.open(image_name) image_small = image.resize((width,height)) pixelated = image_small.resize(image.size,Image.NEAREST) pixelated.save(save_as) Companies Mentioned...
Applying image effects and filters You can select from a large selection of image effects, enhancements, and filters to apply to your images. The available effects include a variety of color balance and level effects, tinting, blurring, pixelating, sharpening, automatic improvement effects, artistic...
