Write Python code to read an 8-bit picture and to create its corresponding 8 bit-planes. Every bit plan is a black and white picture (binary image).

For examples: Choose a coloured image, it should be converted into a 8-bit picture called img8bit. Then, every pixel grey level is converted into binary (base 2) and digit_i is stored into bit plane_i. If I(1,1) = 131 = 1 0 0 0 0 0 1 1

Bitplane7(1,1) = 1 (the most significant bit) 2^7=128

Bitplane6(1,1) = 0

Bitplane5(1,1) = 0

Bitplane4(1,1) = 0

Bitplane3(1,1) = 0

Bitplane2(1,1) = 0

Bitplane1(1,1) = 1 2^1=2

Bitplane0(1,1) = 1 (the least significant bit) 2^0=1

Write Python code to create a 3-bits image by overlapping Bitplane 7, 6 and 5.
