Describe the idea behind Laws Texture detection Why does it

Describe the idea behind Law’s Texture detection. Why does it need to be so complex?

Solution

a texture is an image accepting some statistical properties •in this Similar types of structures repeated over and over again also contains some degree of randomness.

fromthe analysis of Texture it has three typesof analysis

1. Structural approach

2. Statistical approach

3. Fourier approach

Law\'s texture has masks

L5(level)=[1 4 6 4 1 ]

E5(edge) = [ -1 -2 0 2 1]

S5(spot) = [ -1 0 2 0 – 1]

R5(ripple) = [ 1 – 4 6 -4 1]

here

L5 Gaussian gives a center weighted local average

E5 gradient responds to row or column step edges

S5 LOG detects spots

R5 Gabor detects ripples
