In order to evaluate image annotation and object categorisation algorithms, ground truth in the form of a set of images correctly annotated with text describing each image is required. Statistics on the WordNet categories of keywords collected from recent automated image annotation and object categorisation publications and evaluation campaigns are presented. These statistics provide a snapshot...

For the shortage of the traditional evaluation methods of the urban economy, A new evaluation model proposed, establishing an index system of evaluation and decision table on city economy, and extracting important properties of input data from Rough Set and neural network, and evaluation indexes reduced as input of neural network to realize the city's economic strength evaluation , then, using ...

Vanishree et.al proposed a novel unconditionally oblivious polynomial evaluation protocol and they claimed that can fulfill both sender and receiver’s security. Here, this protocol is cryptanalyzed. We find that it has a fatal fault which cannot implement the receiver’s security at all and show the detail analyzing process. Keywords oblivious polynomial evaluation, oblivious transfer, multi-par...

Segmentation is one of the basic steps for image processing. This paper enumerates and gives the comparative study of various image segmentation algorithms and their evaluation methods. Finally after a number of comparative experiments some valuable results are being given. Keywords-Image segmentation, edge detection, thresholding techniques, the evaluation of image segmentation.

This paper presents an evaluation of eleven locally adaptive binarization methods for gray scale images with low contrast, variable background intensity and noise. Niblack’s method with the addition of the postprocessing step of Yanowitz and Bruckstein’s method added performed the best, and was also one of the fastest binarization methods. Keywords— Locally adaptive binarization, Thresholding, ...

Folksonomies provide a free source of keywords describing web resources, however, these keywords are free form and unstructured. In this paper, we describe a novel tool that converts folksonomy tags into semantic metadata, and present a case study consisting of a framework for evaluating the usefulness of this metadata within the context of a particular eLearning application. The evaluation sho...

INTERSOCIAL Project Purpose: Implementation of tools for enhancing SMEs social presence. Results: We describe the architecture, implementation and the features of the SONETA tool. Additionally we report results from the evaluation performed from 3 SMEs with diverse profiles. Conclusion: Results from evaluation shows that SONETA geolocation and search based on keywords functionalities are concep...
