Figure 1:We accomplish image cropping by using NumPy array slicing (image source). When we crop an image, we want to remove the outer parts of the image we are not interested in. We commonly refer to this process as selecting ourRegion of Interest, or more simply, our ROI. We can acc...
要裁剪结果,我们可以在掩膜上使用cv2.boundingRect()获取ROI,然后使用Numpy切片提取结果。对于这个例子,我使用了从图像宽度和高度派生的中心点。 import cv2 import numpy as np # Create mask and draw circle onto mask image = cv2.imread('1.jpg') mask = np.zeros(image.shape, dtype=np.uint8) x,y =...
Katna automates the boring, error prone task of videos key/best frames extraction, video compression and manual time consuming task of image cropping and resizing using ML. In short, you may want to consider using Katna library if you have following tasks: ...
(EasyOCR or PaddleOCR version). Replace 'test.png' in the cv2.imread() function with the path to your input image containing a QR code. Run the script to detect and crop the QR code, and then extract text from the cropped region. The script will display the original image, the cropped...

cepacia SAOCV2 promotes the growth of common beans by several mechanisms such as P mobilization, increasing 44% the plant P content; and promoting also antagonism towards the pathogenic species of Fusarium. Moreover, this result is correlated with a larger number of nodules leading to an increase...
