Pradnya A. Vikhar, P. P. Karde . Content based Image Retrieval (CBIR) System using Threshold based Color Layout Descriptor (CLD) and Edge Histogram Descriptor (EHD). International Journal of Computer Applications. 179, 41 ( May 2018), 39-43. DOI=10.5120/ijca2018916985
The accuracy of any Content Based Image Retrieval (CBIR) system is depend on the accuracy of features extracted from the images. Therefore feature extraction is the first and most important step to develop the CBIR system. Instead of using single feature, most common CBIR system uses combination of color, texture and/or shape to accurately represent an image. MPEG-7 feature extraction provides standards set of descriptors to represent the images and are widely used in many applications. In this paper the concept and area of content based image retrieval system is introduced first. Further it covers the overview of basic MPEG-7 visual feature descriptor; CLD (Color Layout Descriptor) and edge histogram descriptor (EHD) to extract the contents from images. To reduce the overall searching process the advancement in CLD and EHD is suggested by introducing the concept of thresholding.
