python bindings for LSD - Line Segment Detector.

pylsd's Issues

Incorrect license - must be AGPL instead of BSD

This package includes bundled AGPL code, so it can't have a BSD license. This is going to mislead downstream consumers into contaminating their code bases.

Memory Leakage

Environment:
python:3.6.9
pylsd:ocrd-fork-pylsd == 0.0.3
OS: Linux16.04

from pylsd.lsd import lsd
img = cv2.imread("./a.jpg")
gray = cv2.cvtColor(img, cv2.COLOR_BGRA2GRAY)
lines = lsd(gray)

Memory leaks occur when as above code is used.

Import Error while trying to import

I installed the pylsd module using pip3 install pylsd

while trying to run import pylsd i get the below error

Unable to import the pylsd module

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/thalish/.virtualenvs/lib/python3.5/site-packages/pylsd/__init__.py", line 8, in <module>
    from lsd import lsd
ImportError: cannot import name 'lsd'

Does the code not work for python 3.x ?

TypeError: 'module' object is not callable

I get the following error when I try to run example_cv2.py

Traceback (most recent call last):
File "E:\pylsd\example\example_cv2.py", line 16, in
lines = lsd(gray)
TypeError: 'module' object is not callable

How to solve it？

Library Error

I installed pylsd library, however, I go this error

from lsd import lsd
ImportError: cannot import name 'lsd'

Memory leak with some data

Looks like memory leak is still in place in case of some data.

Test data:
https://drive.google.com/file/d/145nGKKlH93v8WIg2IEnZ5e0_GFXCynJQ/view?usp=sharing

Code to reproduce:

import os, psutil
import cv2
import numpy as np

from pylsd.lsd import lsd

img = np.load('array.bin.npy')

process = psutil.Process(os.getpid())

if len(img.shape) == 3:
    img = cv2.cvtColor(img, cv2.COLOR_RGB2GRAY)
    
while True:
    lines = lsd(img, quant=0.7)
    print(process.memory_info().rss)

Release a new version to pypi?

Can you release a new version with the python3 fixes (#1 and #2)?

Thank you!

a try-except syntax error

I am just use pip3.6 to install the package,
but a try-except syntax error occurs when I import it.

pylsd/bindings/lsd_ctypes .py: line 34

except Exception, e:
                pass

fix:

except Exception as e:
                pass

Fix README.md

Fix README.md

• from pylsd import lsd gives error TypeError: 'module' object is not callable.
  It should be from pylsd.lsd import lsd
  
• Markdown headings are not rendering because they should be ### 1.
  not ###1. (No space).
