Vision-Controlled Micro Flying Robots: From System Design to Autonomous Navigation and Mapping in GPS-Denied Environments
(IEEE, 2014)
Autonomous micro helicopters are about to play a major role in tasks like search and rescue, environment monitoring, security surveillance, inspection, etc. If they are further realized in small scale, they can also be ...
A Novel Image Retrieval Based on Visual Words Integration of SIFT and SURF
(2016)
With the recent evolution of technology, the number of image archives has increased exponentially. In Content-Based Image Retrieval (CBIR), high-level visual information is represented in the form of low-level features. ...
A LoCATe‐based visual place recognition system for mobile robotics and GPGPUs
(John Wiley & Sons Ltd, 2017-05)
In this paper, a novel visual Place Recognition approach is evaluated based on a visual vocabulary of the Color and Edge Directivity Descriptor (CEDD) to address the loop closure detection task. Even though CEDD was initially ...
Image Moment Invariants as Local Features for Content Based Image Retrieval using the Bag-of-Visual-Words Model
(Elsevier, 2015)
This paper presents an image retrieval framework that uses affine image moment invariants as descriptors of local image areas. Detailed feature vectors are generated by feeding the produced moments into a Bag-of-Visual-Words ...
Hybrid Cellular Ants for Clustering Problems
(Old City Publishing, 2014)
In the last decade the amount of the stored data related to almost all areas of life has rapidly increased. However, the overall process of discovering knowledge from data demands more powerful clustering techniques to ...
Image Encryption using the Recursive Attributes of the eXclusive-OR Filter
(Springer, 2014)
This paper describes a visual multimedia content encryption approach
based on cellular automata (CA), expanding the work
proposed in [4]. The presented algorithm relies on an attribute
of the eXclusive-OR (XOR) filter, ...
Multimedia Search with Noisy Modalities: Fusion and Multistage Retrieval
(ImageClef, Wikipedia Retrieval Task, 2010)
We report our experiences from participating to the controlled experiment of the ImageCLEF 2010 Wikipedia Retrieval task. We built an experimental search engine which combines multilingual and multi-image search, employing ...
Dynamic Two-Stage Image Retrieval from Large Multimodal Databases
(Springer-Verlag, 2011)
Content-based image retrieval (CBIR) with global features is notoriously noisy, especially for image queries with low percentages of relevant images in a collection. Moreover, CBIR typically ranks the whole collection, ...
Fusion vs. Two-Stage for Multimodal Retrieval
(Springer, 2011)
We compare two methods for retrieval from multimodal collections.
The first is a score-based fusion of results, retrieved visually and textually. The
second is a two-stage method that visually re-ranks the top-K results ...
Bag-of-visual-words vs global image descriptors on two-stage multimodal retrieval
(ACM SIGIR 2011, 2011)
The Bag-Of-Visual-Words (BOVW) paradigm is fast becoming a
popular image representation for Content-Based Image Retrieval
(CBIR), mainly because of its better retrieval effectiveness over
global feature representations ...
