image processing - Band-pass convolution/diff of Gaussians filter -

-

I am reading a call to use a band-pass compilation using the difference from the Gaussian filter. How does the image processing operation work?

This is probably the difference of the gauses filter.

See signal processing as a conversion of the original signal with a filter kernel. This frequency is equal to the conversion signal and filter in the domain, where it multiplies and later it turns into a local domain.

Obfuscating Python code? -

I'm looking for a way to hide my Python source code. print "Hello World!" How can I encode this example so that it is not human-readable? I have been asked to use Base 64 but I'm not sure how. itemprop = "text"> It is limited only, first level ambiguous resolution, but has built-in: byte-code in Python Is a compiler for: dragon-o-m py_compile & lt; Your program.py & gt; creates a .pyo file with a byte-code, and where the docstrings are removed, etc. You can rename .pyo with the .py extension, and python & lt; Your program.py & gt; runs as your program, but it does not have your source code. PS : If your program blur modules like this, you need to rename them with the .pyc suffix (I Not sure it will not break a day), or you can work with .pyo and run them with python -o ... .pyo ( Import should work). This will allow dragon to search your modules (otherwise, Python looks for the .py module).
