Self-feedback image retrieval algorithm based on annular color moments
2019
EURASIP Journal on Image and Video Processing
Preserved Fulltext
To further contribute to the research, this paper proposes a self-feedback image retrieval algorithm based on annular color moments. ...
In this approach, hashing sequences of color moments based on annular segmentation are extracted to be used as feature vectors for initial retrieval. ...
Her research interests are image processing, pattern recognition and data mining. ...

In this proposed work, the features like color with HSV color space, color moments and Hu moments are employed to retrieve similar images. ...
In today's digital era, several of the image retrieval systems focus on retrieving images using features from images themselves such as color, shape and textures and are referred as low-level features. ...
Introduction Content based image retrieval (CBIR) is a technique used in computer vision applications, using which the similar images from large databases are found and returned as a resultant set based ...
