当使用PIL.Image读取图像时,如果直接使用numpy.array()转换会出现错误: {代码...} 此时,上述最后一行在执行时会出现错误: {代码...} 解决办法如下: {代...

im=Image.fromarray(result*255.0) im.convert('L').save("1.jpg",format='jpeg') 这是我得到的128*256大小的灰度图 二、利用CV库 看这篇博客,这个方法和利用PIL库有异曲同工之处 主要步骤 1.生成普通python数组(bytearray(),os.urandom())
# Open image using Pillow library img=Image.open('image.jpg')# Convert image to NumPy array np_array=np.array(img)# Save NumPy array toCSVfile np.savetxt('output.csv',np_array,delimiter=',',fmt='%d')# Print the shapeofthe NumPy arrayprint("Shape of NumPy array:",np_array.shape)...

首先,导入Pillow库中的Image模块。 接着,使用Image.open方法打开您想要转换的图片。 然后,使用convert方法将图片转换成灰度模式,以简化后续的二进制转换过程。 最后,使用tobytes方法将图片转换成二进制代码。 下面是一个简单的代码示例: from PIL import Image ...
I want to create a PIL image from a NumPy array. Here is my attempt: # Create a NumPy array, which has four elements. The top-left should be pure# red, the top-right should be pure blue, the bottom-left should be pure green,# and the bottom-right should be yellow.pixels = np....
