Method Detail

loadImage

public Vertex loadImage(java.lang.String urlPath,
                        Network network)

Load an image from a URL.

loadImageBytes

public byte[] loadImageBytes(java.lang.String urlPath)

Load an image from a URL.

loadImageFileBytes

public byte[] loadImageFileBytes(java.lang.String filePath)

Load an image from a file.

loadImageFile

public Vertex loadImageFile(java.lang.String filePath,
                            Network network)

Load an image from a file.

loadImage

public Vertex loadImage(byte[] image,
                        Network network)

Load binary image.

matchImage

public Vertex matchImage(byte[] image,
                         Vertex tag,
                         double error,
                         Network network)
                  throws java.io.IOException

Self API. Load an image from the URL and find the closest matching image.

Throws:

java.io.IOException

coupledHueSat

public double[] coupledHueSat(byte[] image)
                       throws java.io.IOException

HSV stores color information in Hue and Saturation while intensity is in Value. This computes a 2D histogram from hue and saturation only, which makes it lighting independent.

Throws:

java.io.IOException

loadImage

public Vertex loadImage(Vertex source,
                        Vertex url)

Self API. Load an image object from the URL.

matchImage

public Vertex matchImage(Vertex source,
                         Vertex url,
                         Vertex tag,
                         Vertex error)

Self API. Find the closest matching image on the tag object with the URL image.
