Research on Indoor Scene Classification Mechanism Based on Multiple Descriptors Fusion

Algorithm 1

Greedy descriptor filtering algorithm.

	Input: descriptor list---ℒ
	descriptor classification accuracy list---
	descriptor size list---
(1)	for do
(2)
(3)	end
(4)	Divide the descriptor size into, , and three continuous intervals
(5)	for do
(6)	Divide ℒ into new lists
(7)	Sort the descriptors in in order of weight values from largest to smallest
(8)	for do
(9)	Filter the descriptor [1] with the largest weight in and add [1] to Φi
(10)	if [j − 1] is filtered and
	then
(11)	Add [j] to αi
(12)	else
(13)	end
(14)	end
(15)	end
	Output: filtered descriptor list---α
