image = PIL.Image.open(file_name) lst.append(np.array(image)) arr = numpy.array(lst) 即,在list中的元素都已转化为numpy.array,而非直接的Image对象。
This tutorial explains how we can convert a NumPy array to a PIL image using the Image.fromarray() from the PIL package.
This example illustrates converting a 3-channel RGB PIL Image to 3D NumPy array and back: importnumpyimportPIL# Convert PIL Image to NumPy arrayimg=PIL.Image.open("foo.jpg")arr=numpy.array(img)# Convert array to Imageimg=PIL.Image.fromarray(arr) Tried with:...
如果你有其他特定的转换需求,比如将数组转换为 PIL 图像对象,你可以使用 PIL 库中的 Image.fromarray() 方法。 总之,当你遇到 'numpy.ndarray' object has no attribute 'xxx' 这类错误时,首先应该检查你调用的属性或方法名是否正确,或者是否使用了 NumPy 提供的正确方法来达到你的目的。

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。
convert() PIL有九种不同模式: 1,L,P,RGB,RGBA,CMYK,YCbCr,I,F。1.1 img.convert('1') 为二值图像,非黑即白。每个像素用8个bit表示,0表示黑,255表示白。1.1.1 Code1 from PIL import Image 2 3 4 def convert_1(): 5 i Image Code 二值图像 转载 编程梦想翱翔者 2023-06-04 13:38:33 ...
Keras provides the img_to_array() function for converting a loaded image in PIL format into a NumPy array for use with deep learning models. The API also provides the array_to_img() function that can be used for converting a NumPy array of pixel data into a PIL image. This can be us...
