A Sparse Representation Based Method to Classify Pulmonary Patterns of Diffuse Lung Diseases

Table 1

Three proposed methods for evaluation of sparse representation approaches.

(a) Proposed methods

Method	Dictionary learning	Sparse coding
SR1	-SVD	OMP
SR2	-Means	OMP
SR3	-Means	OMP1

(b) Experiments on the evaluation of sparse representation approaches

Evaluation	Comparison of methods
-SVD versus -Means	SR1 and SR2
OMP versus OMP1	SR2 and SR3
