| Summary: | Image retrieval forms a major problem when a large database is considered. Content
Base Image Retrieval (CBIR) makes use of the available visual features of the image
and helps in retrieving similar image as that of the query image. In the CBIR
method, each image stored in the database has its features extracted and compared to
the features of the query image. Thus, it involves two processes, feature extraction
and feature matching. In this thesis, four techniques have been used, which are the
Average of Red, Green and Blue Color Channels (Average RGB), Local Color
Histogram (LCH), Global Color Histogram (GCH) and Color Moment of Hue,
Saturation and Brightness Value (HSV) to retrieve relevant images based on colour.
These techniques are applied on the collection of three images chosen randomly
from each class of Wang images database. The performance of each technique has
been individually evaluated, in terms of Execution Time, Precision, Recall,
Accuracy, Redundancy Factor and Fall Rate. The results were then analysed and
compared. The comparison was shown in bar graphs that the Average RGB
technique has the best performance, where it obtained high accuracy. As a
conclusion to the report, this comparative study contributes to the image searching
field, by measuring the performance for several CBIR techniques using more
commonly used parameters. |
