The program determines a suitable algorithm for pre-processing, segmenting, and post-processing a set of images for a specific application to distinguish crucial regions of interest within the image. CVIP-ATAT provides a graphical user interface (GUI) to input algorithms for testing and analysis. Users can define multiple processes to test at ...
The Hough transform [3] can be used to detect lines and the output is a parametric description of the lines in an image, for example ρ = r cos(θ) + c sin(θ). [1] If there is a line in a row and column based image space, it can be defined ρ, the distance from the origin to the line along a perpendicular to the line, and θ, the angle of the perpendicular projection from the origin to the ...
The Lambda2 method, or Lambda2 vortex criterion, is a vortex core line detection algorithm that can adequately identify vortices from a three-dimensional fluid velocity field. [1] The Lambda2 method is Galilean invariant , which means it produces the same results when a uniform velocity field is added to the existing velocity field or when the ...
The Canny algorithm contains a number of adjustable parameters, which can affect the computation time and effectiveness of the algorithm. The size of the Gaussian filter: the smoothing filter used in the first stage directly affects the results of the Canny algorithm. Smaller filters cause less blurring, and allow detection of small, sharp lines.

LBPLibrary is a collection of eleven Local Binary Patterns (LBP) algorithms developed for background subtraction problem. The algorithms were implemented in C++ based on OpenCV. A CMake file is provided and the library is compatible with Windows, Linux and Mac OS X. The library was tested successfully with OpenCV 2.4.10.
A robust background subtraction algorithm should be able to handle lighting changes, repetitive motions from clutter and long-term scene changes. [2] The following analyses make use of the function of V ( x , y , t ) as a video sequence where t is the time dimension, x and y are the pixel location variables. e.g. V (1,2,3) is the pixel ...
All newer developments and algorithms appear in the C++ interface. There are language bindings in Python, Java, and MATLAB/Octave. The application programming interface for these interfaces can be found in the online documentation. [14] Wrapper libraries in several languages have been developed to encourage adoption by a wider audience.
