• A smart UDP protocol analyzer?

  - by ripper234

  Is there a "smart" UDP protocol analyzer that can help me reverse engineer a message based protocol?

• Detecting and handling third-party library filehandle leaks in Java

  - by tucuxi

  Is there any way to detect and handle whether a Java library is correctly releasing file-handles (via "close") from within a Java program that is using said library, short of having access to the actual library code and inserting the corresponding "finally close" statements? If detection is feasible, is there any way to close those file-handles without a reference to the Reader (or FileInputStream) that was reading the file?

• Detecting Markers Using OpenCV

  - by Hamza Yerlikaya

  I am trying to detect various objects containing colored markers, so a red blue green marker identifies object A, and a red blue red marker identifies object B. My problem is I can't use template matching cause objects can be rotated, currently I am thinking about check for each color then find the object by checking the distance between colors but it seems inefficient, so my question is there a better way to do this?
