I am reading thousands of images (all three channels), one by one, in form of a numpy ndarray and append them to a list. At the end I want to convert this list into a numpy array: import numpy as np from PIL import Image def read_image_path(path, img_size=227): img = Image...

This tutorial explains how we can convert a NumPy array to a PIL image using the Image.fromarray() from the PIL package.
img_numpy = cv2.imdecode(img_buffer_numpy, 1) 1. 2. 3. 4. 5. PIL 转 cv2 img= Image.open("test.jpg") img = cv2.cvtColor(np.asarray(img), cv2.COLOR_RGB2BGR) 1. 2. cv2 转 PIL img = cv2.imread("test.jpg") img= Image.fromarray(cv2.cvtColor(img,cv2.COLOR_BGR2RGB)) ...
在了解了基本知识后,我查阅了很多资料想把 RGBA 图片抓换成 RGB 图片,看了很多都是使用图片库自带的图片类型转换库,比如 PIL 的Image.open(img_path).convert('RGBA') 类似代码或者opencv使用 cv2.cvtColor(image, cv2.COLOR_RGBA2BGR) ,但是都不是我想要和效果,后来终于找到了正确的解决方法。
