This paper provides a novel content-based image retrieval algorithm based on ROI (Region Of Interest) by using SIFT (Scale Invariant Feature Transform) feature matching. SIFT descriptors, which are invariant to image scaling and transformation and ...
Content-based image retrieval is an important research topic in computer vision. We present a new method that combines region of interest (ROI) detection and relevance feedback. The ROI based approach is more accurate in describing the image content ...
Region of interest (ROI) extraction plays an important part in image processing and analysis. Based on rough set theory, a ROI extraction algorithm was presented in the paper. Firstly, a rough ROI was determined based on the prior knowledge. Then, ...
