Feature encoding is a crucial step in BOW image representation. The standard BOW model assigns each image feature to the nearest visual-word without making a distinction between the features that are assigned to the same words. This hard feature assignment leads to high quantization errors and degrades the learning capacity of the classifiers in image classification. We propose a fuzzy feature encoding approach to overcome the uncertainty problem in BOW through assigning each image feature to the visual-words with some membership degrees. We employ two classification techniques, Naive Bayesian and SVM, to evaluate the effect of the fuzzy assignment in image classification. Experiments conducted on image datasets show that fuzzy feature encoding significantly improves the classification accuracy.

A Novel Bag-of-Visual-Words Approach for Geospatial Object Detection
Aytekin, Caglar; Alatan, Abdullah Aydın (2011-04-29)
A novel bag-of-visual-words algorithm is presented with two extensions compared to its classical version: exploiting scale information and weighting visual words. The scale information that is already extracted with SIFT detector is included as an additional element to the SIFT key-point descriptor, while the visual words are weighted during histogram assignment proportional to their importance which is measured by the ratio of their occurrences in the object to the occurrences in the background. The algori...
A transcoding robust data hiding method for image communication applications
Candan, Çağatay (2005-09-14)
We present a data embedding method for image communication applications. Our goal is to implement novel multimedia applications such as multi-language captions, interactive programming and title specific features over the existing image communication channel. To this aim, we present a data embedding method for JPEG images which has the desired degree of robustness to transcoding or bitrate adjustments that may take place in the communication channel. The described system is designed for JPEG images but can ...
An Improved BOW Approach Using Fuzzy Feature Encoding and Visual-word Weighting
Altintakan, Umit L.; Yazıcı, Adnan (2015-08-05)
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 clo...
A shape deformation algorithm for constrained multidimensional scaling
Sahillioğlu, Yusuf (2015-12-01)
We present a new Euclidean embedding technique based on volumetric shape registration. Extrinsic representation of the intrinsic geometry of a shape is preferable in various computer graphics applications as it poses only a small degrees of freedom to deal with during processing. A popular Euclidean embedding approach to achieve such a representation is multidimensional scaling (MDS), which, however, distorts the original geometric details drastically. Our method introduces a constraint on the original MDS ...
A NOVEL BOVW MIMICKING END-TO-END TRAINABLE CNN CLASSIFICATION FRAMEWORK USING OPTIMAL TRANSPORT THEORY
Gürbüz, Yeti Ziya (2019-01-01)
An end-to-end trainable convolutional neural network (CNN) framework which mimics bag of visual words (BoVW) is proposed for image classification. To this end, a new paradigm for histogram-like image representation is introduced and optimal transport (OT) distance is utilized for the similarity assessment. Any patch of an image is considered as a unique visual word and the image is represented as the uniform histogram of the visual words with the histogram bins associated to embedding vectors according to t...
