Performance Analysis For CBIR Using DTCWT and Hu Moment with GCV FeatureExtraction

Abstract

Content Based Image Retrieval (CBIR) has been the most important thing for searching related content on the
internet in the form of images, data etc. The main work of CBIR is to get retrieve efficient, perfect and fast results. This
paperis associated with color, shape and texture feature. In this research, implement a new technique for CBIR by dual
tree complex wavelet transform (DTCWT), Hu moment, color moment and global correlation vector (GCV)features
usingSupport vector machine (SVM) categorizing. In the feature extraction, firstly extract texture feature using DTCWT
for resolving the problematic of redundant CWT. In this paper, it can integrate the advantages of histogram statistics and
Color Structure Descriptor (CSD) to characterize color and consistency features respectively.After that, extract color
feature using color momentin RGB color space for improving computation and efficiency. The experimental dataset
contains 1100 images, including horses, elephants, food, African people,texture, etc. The match size is calculated using
weighted L1 (WL1), Euclidean distance (ED), L1 (Manhattan distance) and Minkowski distance (MD). For improving
effectiveness of the system, classify data using SVM. The performance analysis is based on precision, recall, time and Fmeasure.
