public class ImageInputSynapse
extends StreamInputSynapse

This synapse collects data from Image files or Image objects and feeds the data from the Images into the Neural network. GIF, JPG and PNG image file formats can be read. The synapse operates in two modes, colour and grey scale.

Colour Mode In colour mode ImageInputSynapse produces seperate RGB input values in the range 0 to 1 from the image. So using an image of width 10 and height 10 there will be 10x10x3 inputs in the range 0 to 1. The individual colour components are calculated by obtaining the RGB values from the image. These value are initially in an ARGB format. Transparency is removed and the RGB value extracted and normalised between 0 and 1.

Non Colour Mode / Grey Scale Mode In this mode the synapse treats each input value as a grey scale value for each pixel. In this mode only Width*Height values are required. To produce the final image the Red, Green and Blue components are the set to this same value. The grey scale component is calculated by obtaining the RGB values from the image. These value are initially in an ARGB format. Transparency is removed and the RGB value extracted, averaged and normalised to produce one grey scale value between 0 and 1.
