Question

Explain the bit-plain slicing ? Subject is digital image processing

Answer 1

Bit plane slicing is well known technique used in Image processing. In image compression Bit plane slicing is used. Bit plane slicing is the conversion of image into multilevel binary image.
The gray level of each pixel in a digital image is stored as one or more bytes in a computer.
For an 8-bit image, 0 is encoded as 00000000 and 255 is encoded as 11111111.
Any number between 0 t0 255 is encoded as one byte.
The bit in the far left side is referred as the Most Significant Bit (MSB) because a change in that bit would significantly change the value encoded by the byte.
The bit in the far right is referred as the Least Significant Bit (LSB), because a change in this bit does not change the encoded gray value much.

The three main goals of bit plane slicing is:

Converting a gray level image to a binary image.
Representing an image with fewer bits and corresponding the image to a smaller size
Enhancing the image by focusing:

The bit plane representation of an eight-bit digital image is given by an image attached with this.

Bit plane slicing is a method of representing an image with one or more bits of the byte used for each pixel. One can use only MSB to represent the pixel, which reduces the original gray level to a binary image. The three main goals of bit plane slicing is:

Converting a gray level image to a binary image.
Representing an image with fewer bits and corresponding the image to a smaller size
Enhancing the image by focussing.
then separating the bit planes obtained.
