将图像分成具有相同像素数据的多个图像 [英] Dividing a image into multiple images of equal pixel data

问题描述

我有一个灰度图像 im

如果总计是所有像素值的总和，如何将 im 拆分为5个具有以下属性的图像：

If total is the sum of all pixels' values, how do I split im into 5 images with the following properties:

• 所有像素值的总和是总计的1/5


• 缺少要求...


• ...

我正在使用python。但是，任何其他语言的建议也将受到赞赏。

I am using python. But suggestion in any other language will also be appreciated.

我使用以下代码计算像素数据。

I have used the following code for counting pixel data.

from PIL import Image

im = Image.open('capture.jpg')
im_grey = im.convert('LA') # convert to grayscale
width,height = im.size

total=0
for i in range(0,width):
    for j in range(0,height):
        total += im_grey.getpixel((i,j))[0]

print "The sum of all pixels' values in im is :" 
print total
print "1/5 of that sum is :" 
print total/5

任何建议都应该受到赞赏。

any suggestions should be appreciated.

推荐答案

你原来的问题很难。但是，看看你发表的评论，我认为这是一个简单的问题。您可以从上到下扫描图像，并对像素求和。当总和达到sum_all_pixels / 5时，您就找到了第一个区域。将总和重置为零，然后继续扫描第二个区域。我希望你明白我的意思。

Your original problem is a hard one. But, looking at the comments you made, I think it is a simple problem. You can scan the image from top to bottom, and sum the pixels. When the sum reaches the sum_all_pixels/5, then you have found the first area. Reset the sum to zero, and continue scanning for the second area. I hope you understand what I mean.
