Class FractionRgbData

java.lang.Object

org.neuroph.imgrec.FractionRgbData

public class FractionRgbData
extends java.lang.Object

The intention of this class is to allow you to pay up front (at construction) the compute cost of converting the RGB values in a BufferedImage into a derived form. The major benefit of using this class is a single loop that grabs all 3 color channels (red, green, and blue) from each (x,y) coordinate, as opposed to looping through each color channel (red, green, or blue) when you need it. If you only need a single color from the channels (red, green, or blue) then using this class may be more expensive than a custom solution. In the event that it needs to be parsed, the flattened rgb values array contains all the red first, followed by all the green, followed by all the blue values. The flattened array size should be divisible by 3.
