六、形态图像处理 在本章中,我们将讨论数学形态学和形态学图像处理。形态图像处理是与图像中特征的形状或形态相关的非线性操作的集合。这些操作特别适合于二值图像的处理(其中像素表示为 0 或 1,并且根据惯例,对象的前景=1 或白色,背景=0 或黑色),尽管它可以扩展到灰度图像。 在形态学运算中,使用结构元素(小模...
testlines.py - Open a file and print out 100 lines of the set line variable. tweeter.py - Tweet text or a picture from the terminal. serial_scanner.py - List available serial ports in use on Linux and Windows systems. get_youtube_view.py - Get more views for YouTube videos and rep...
The variable for the data size, n, now gets a specific datatype. This line is new: we create a memory view of the data inside the array a. This allows Cython to generate code that can access the data inside the array directly. As with n, we also specify a type for the loop inde...
If you want to use a different version of Python than the default, you can change the Python version by setting thePYTHONenvironment variable to the path of thepython(orpython3etc.) executable and then re-runningPkg.build("PyCall"). In Julia: ENV["PYTHON"] = "... path of the python...
Beachten Sie, dass dieif-Anweisung im vorherigen Beispiel beendet wurde, nachdem der erste logische Test mit dem Ergebnis TRUE gefunden wurde. Die Variableywurde auf „1“ festgelegt und somit tatsächlich auf eine ungerade Zahl ist. Dieif-Anweisung wurde jedoch ausgeführt und beendet,...
and extensible functionality known asmagicsintroduced by the percent (%) character. It also provides shell escapes, allowing a Python variable to receive the result of a shell command. You can use a question mark to query an object’s documentation (two question marks for extended documentation)...
access by getting py-spy to create the process (py-spy record -- python myprogram.py) but attaching to an existing process by specifying a PID will usually require root (sudo py-spy record --pid 123456). You can remove this restriction on Linux by setting theptrace_scope sysctl variable...
