In Content Based Image Retrieval (CBIR) system, Relevance Feedback (RF) technique can substantially promote retrieval accuracy. As a popular algorithm of Relevance Feedback, Query movement was widely applied in this area and it moves the query in the input space towards relevant images. However, traditional Query Movement algorithm has significant disadvantages. It is to reduce the similarity between...
A method of patterns recognition was presented based on fuzzy rough sets. Dynamic clustering algorithm and method of analysis of variance is introduced to fuzzify the continuous condition attribute, and fuzzy membership functions is derived, which avoided losing information caused by discretization in rough set theory. F test is introduced to judge the valid analysis of clustering, which has overcome...
In this paper, a computer application program to process electronic microscope images of plant pollen is presented. We use contrast enhancement to separate pure object pollen from original image. Hough edge detector is used to extract complete and inside-detail-kept edges from pure object image for recognition. Pre-process such as smoothing, grayscale equipoise, etc., is performed to remove noise...
