问题 So I am trying to extract text from image. And as the quality and size of image is not good, it is giving inaccurate results.

Few Examples of images: 回答1: In the provided example of image the text is visually of quite good quality, so the question is how it comes that OCR gives inaccurate results? To illustrate the conclusions

问题 I have an A4 png image with some text in it, it's transparent, my question is, how can I crop the image to only have the text, I am aware of cropping in PIL, but if I set it to fixed values, it will not be able to crop another image that has that text in another place. So, how can I do it so it finds where the text, sticker, or any other thing is placed on that big and empty image, and crop it so the thing fits perfectly? Thanks in advance! 回答1: You can do this by extracting the alpha channel

问题 Tkinter doesn't open the image. We can ask the opening incorrectly, we need help. I need it to open the image through the menu. be sure to use pil, as the image can be anything. There are no errors in the syntax. Thank you = ) from tkinter import Tk, Frame, Menu, Canvas, PhotoImage import easygui from PIL import Image, ImageFilter, ImageTk def input_file(): a = easygui.fileopenbox(filetypes=["*.jpg"]) original = Image.open(a) original = original.resize((799, 799), Image.ANTIALIAS) photoimg =

问题 I want to use the images stored in a dictionary, to convert it to a GIF. The images in the dictionary is like this type: people={ 1: <PIL.Image.Image image mode=RGBA size=16x16 at 0x10962C510>, 2: <PIL.Image.Image image mode=RGBA size=16x16 at 0x1098D7F90>, 3: <PIL.Image.Image image mode=RGBA size=16x16 at 0x1098D7F50>} I think is a Pillow image. But why do I always get this error: 'Image' object has no attribute 'read' What does it mean? The full error: File "/***view.py", line 266, in

问题 I always thought, doing from x import y and then directly use y , or doing import x and later use x.y was only a matter of style and avoiding naming conflicts. But it seems like this is not always the case. Sometimes from ... import ... seems to be required : Python 3.7.5 (default, Nov 20 2019, 09:21:52) [GCC 9.2.1 20191008] on linux Type "help", "copyright", "credits" or "license" for more information. >>> import PIL >>> PIL.__version__ '6.1.0' >>> im = PIL.Image.open("test.png") Traceback
