where Bi represents a binary digit. A bit plane from the imagecan be formed by taking the binary digit Bi (0th bit plane from the image is formed by combining theith bit plane from the red, green and blue bands. The collectionof all the bit planes in a digital image forms a second type decomposition of adigital image.

Of course, these examples are simplified to illustrate the process. An actualcover and message will involve many more pixels and bits. Likewise, a channel ina color image will involve one bit in the red band, one in the green band, and onein the blue band. Thus a channel in a color image will have three times as manybits as one in a greyscale image of the same size.

The decomposition of a color image into its component bands is shown in thefigures below. Figures 2 through 4 show the red band, blue band, and green bandof the image shown in Figure 1.

Each band value in a digital image is represented as a unsigned eight-bitinteger. Hence, a greyscale pixel can represent 256 shades of grey with 0representing black and 255 white. Likewise, each of the bands in a color pixelcan represent 256 shades of the band color. In each case, 0 represents anabsence of the band color and 255 represents the band color. (eg. A red bandvalue of 255 represents red.) The values between 0 and 255 representsuccessively lighter shades of the band color.

A digital image can be represented as a rectangular grid of pixels (the dotswe see), where eachpixel displays either a color or shade of grey. For a greyscale image, eachpixel has a singlevalue. For a color image, each pixel has a red, a eight green, and a bluecomponent. These components are referred to as bands. Hence, a color pixel has three bands and a greyscale pixel has a single band.

The CSImage class provides the basic functionality needed to extract the colorbands of a digital image and the bitwise operators provide means of encoding/decodinga message. However, the process of inserting the bits in a cover or extractingthem form a stego image is tricky at best. In order to make these processeseasier it would is helpful to provide two additional classes-one that produces astream of bits from the channels of an image and one that consumes a stream bitsby embedding them in an image. Figure 10 shows the design of the ImageInputStreamclass-the bit stream producer. Figure 11 shows the design of theImageOutputStream-the bit stream consumer. Note that the implementation ofeach involves keeping track of current bit position in terms of the column,row, and band.
