The document discusses digital image processing, focusing on the contribution of specific bits to the overall image appearance. Each pixel, represented by 8 bits, comprises 8 one-bit planes, with higher order bits conveying visually significant data while lower order bits contribute subtler details. Notably, the highest bit plane corresponds to an image thresholded at gray level 128.

3. To highlight the contribution made to the
total image appearance by specific bits.
– i.e. Assuming that each pixel is represented by 8 bits, the image
is composed of 8 1-bit planes.

4. To highlight the contribution made to the
total image appearance by specific bits.
– i.e. Assuming that each pixel is represented by 8 bits, the image
is composed of 8 1-bit planes.
– Plane 1 contains the least significant bit and plane 8 contains the most
significant bit.

5. To highlight the contribution made to the
total image appearance by specific bits.
– i.e. Assuming that each pixel is represented by 8 bits, the image
is composed of 8 1-bit planes.
– Plane 1 contains the least significant bit and plane 8 contains the most
significant bit.
– Useful for analyzing the relative importance played by each bit
of the image

– Useful for analyzing the relative importance played by each bit of the
image
– Only the higher order bits (top four) contain visually significant data. The other bit
planes contribute the more subtle details
