Classes

AdaptiveManifoldFilter

Interface for Adaptive Manifold Filter realizations.

Below listed optional parameters which may be set up with Algorithm::set function.

  • member double sigma_s = 16.0 Spatial standard deviation.
  • member double sigma_r = 0.2 Color space standard deviation.
  • member int tree_height = -1 Height of the manifold tree (default = -1 : automatically computed).
  • member int num_pca_iterations = 1 Number of iterations to computed the eigenvector.
  • member bool adjust_outliers = false Specify adjust outliers using Eq. 9 or not.
  • member bool use_RNG = true Specify use random number generator to compute eigenvector or not.
ContourFitting

Class for ContourFitting algorithms. ContourFitting matches two contours minimizing distance using their Fourier descriptors, a scaling factor, an angle rotation and a starting point factor adjustment.

DTFilter

Interface for realizations of Domain Transform filter.

DisparityFilter

Main interface for all disparity map filters.

DisparityWLSFilter

Disparity map filter based on Weighted Least Squares filter (in form of Fast Global Smoother that is a lot faster than traditional Weighted Least Squares filter implementations) and optional use of left-right-consistency-based confidence to refine the results in half-occlusions and uniform areas.

EdgeAwareInterpolator

Sparse match interpolation algorithm based on modified locally-weighted affine estimator and Fast Global Smoother as post-processing filter.

EdgeBoxes

Class implementing EdgeBoxes algorithm from @cite ZitnickECCV14edgeBoxes

EdgeDrawing

Class implementing the ED (EdgeDrawing), EDLines, EDPF, EDCircles and ColorED algorithms.

EdgeDrawingParams

Parameters for EdgeDrawing algorithms.

FastBilateralSolverFilter

Interface for implementations of Fast Bilateral Solver.

FastGlobalSmootherFilter

Interface for implementations of Fast Global Smoother filter.

FastLineDetector

Class implementing the FLD (Fast Line Detector) algorithm described in @cite Lee14.

GuidedFilter

Interface for realizations of Guided Filter.

RFFeatureGetter

Helper class for training part of [P. Dollar and C. L. Zitnick. Structured Forests for Fast Edge Detection, 2013].

RICInterpolator

Sparse match interpolation algorithm based on modified piecewise locally-weighted affine estimator called Robust Interpolation method of Correspondences (RIC), and Variational and Fast Global Smoother as post-processing filter. RICInterpolator is an extension of EdgeAwareInterpolator; its main concept is a piece-wise affine model based on over-segmentation via SLIC superpixel estimation, with an efficient propagation mechanism to estimate among the piece-wise models.

ScanSegment

Class implementing the F-DBSCAN (Accelerated superpixel image segmentation with a parallelized DBSCAN algorithm) superpixels algorithm.

The algorithm uses a parallelised DBSCAN cluster search that is resistant to noise, competitive in segmentation quality, and faster than existing superpixel segmentation methods. The output is deterministic when the number of processing threads is fixed, and requires the source image to be in Lab colour format.

SparseMatchInterpolator

Main interface for all filters, that take sparse matches as an input and produce a dense per-pixel matching (optical flow) as an output.

StructuredEdgeDetection

Class implementing edge detection algorithm from @cite Dollar2013 :

SuperpixelLSC

Class implementing the LSC (Linear Spectral Clustering) superpixels algorithm described in @cite LiCVPR2015LSC.

LSC(Linear Spectral Clustering) produces compact and uniform superpixels with low computational costs.Basically, a normalized cuts formulation of the superpixel segmentation is adopted based on a similarity metric that measures the color similarity and space proximity between image pixels.LSC is of linear computational complexity and high memory efficiency and is able to preserve global properties of images.

SuperpixelSEEDS

Class implementing the SEEDS (Superpixels Extracted via Energy-Driven Sampling) superpixels algorithm described in @cite VBRV14.

The algorithm uses an efficient hill-climbing algorithm to optimize the superpixels' energy function that is based on color histograms and a boundary term, which is optional.The energy function encourages superpixels to be of the same color, and if the boundary term is activated, the superpixels have smooth boundaries and are of similar shape. In practice it starts from a regular grid of superpixels and moves the pixels or blocks of pixels at the boundaries to refine the solution.The algorithm runs in real-time using a single CPU.

SuperpixelSLIC

Class implementing the SLIC (Simple Linear Iterative Clustering) superpixels algorithm described in @cite Achanta2012.
