Image Splicing-Based Forgery Detection Using Discrete Wavelet Transform and Edge Weighted Local Binary Patterns

Algorithm 1

Computation of DWT-DRLBP.

(1)	RGB image I, the number K of blocks  a) Convert I to YCbCr  b) DWT-DRLBP descriptor
(2)	for each channel of image I
(3)	a) Apply 2D-DWT on Ch, Sb [LL, LH, HL, HH]
(4)	end for
(5)	S
(6)	Divide S into blocks:
(7)	for each block
(8)	Compute DRLBP histogram
(9)
(10)
(11)
(12)	end for
