The bag-of-words (BOW) has become a popular image representation model with successful implementations in visual analysis. Although the original model has been improved in several ways, the utilization of the Fuzzy Set Theory in BOW has not been investigated thoroughly. This paper presents a fuzzy feature encoding approach to address the problems associated with the hard and soft assignments of image features to the visualwords. Our encoding method assigns each image feature to only the first and second closest words in the codebook to overcome the word-uncertainty problem. Moreover, we introduce a new word-weighting scheme for image categories based on image histograms. Experiments conducted on some image datasets show that both methods increase the BOW performance in content based image retrieval.

Robust, object-based high-resolution image reconstruction from low-resolution video
Eren, Pekin Erhan; Sezan, MI; Tekalp, AM (1997-10-01)
We propose a robust, object-based approach to high-resolution image reconstruction from video using the projections onto convex sets (POCS) framework. The proposed method employs a validity map and/or a segmentation map. The validity map disables projections based on observations with inaccurate motion information for robust reconstruction in the presence of motion estimation errors; while the segmentation map enables object-based processing where more accurate motion models can be utilized to improve the q...
An mpeg-7 video database system for content-based management and retrieval
Çelik, Çiğdem; Çiçekli, Fehime Nihan; Department of Computer Engineering (2005)
A video data model that allows efficient and effective representation and querying of spatio-temporal properties of objects has been previously developed. The data model is focused on the semantic content of video streams. Objects, events, activities performed by objects are the main interests of the model. The model supports fuzzy spatial queries including querying spatial relationships between objects and querying the trajectories of objects. In this thesis, this work is used as a basis for the developmen...
Accurate equivalent models of sandwich laminates with honeycomb core and composite face sheets via optimization involving modal behavior
Cinar, Okan; Erdal Erdoğmuş, Merve; Kayran, Altan (2017-03-01)
An approach is introduced for determining accurate two-dimensional equivalent laminated models of sandwich laminates with honeycomb core and composite facesheets by optimization involving modal behavior. The approach relies on minimizing the objective function which is defined as the sum of the square of the differences between the natural frequencies of the honeycomb sandwich laminate estimated by the finite element analysis of the 3D detailed model with the actual honeycomb core geometry and by the 2D equ...
A NEW HEURISTIC APPROACH FOR THE MULTIITEM DYNAMIC LOT-SIZING PROBLEM
KIRCA, O; KOKTEN, M (Elsevier BV, 1994-06-09)
In this paper a framework for a new heuristic approach for solving the single level multi-item capacitated dynamic lot sizing problem is presented. The approach uses an iterative item-by-item strategy for generating solutions to the problem. In each iteration a set of items are scheduled over the planning horizon and the procedure terminates when all items are scheduled. An algorithm that implements this approach is developed in which in each iteration a single item is selected and scheduled over the planni...
Optimization of the seismic isolation parameters for bridges
Dicleli, Murat; Amiri, Shahin Nayyeri (null; 2007-11-29)
Köprülerde kullanılan deprem izolatörleri, genellikle çift doğrusal yük-deplasman eğrileriyle modellenir. Bu çalışmada, deprem izolatörlerinde oluşan yük ve deplasmanı asgariye indirmek için, sismik izolasyon sistemini tanımlayan parametrelerden karakteristik mukavemetin optimizasyonunun yapılması hedeflenmiştir. Bu amaçla, öncelikle deprem izolatörlerinin optimum deplasman ve kuvvet değerlerini etkileyen parametreler belirlenmiştir. Bu çalışmada göz önüne alınan parametreler, köprü alt yapı rijitliği, sönü...
