However,in most cases, the evaluation of these systems is related to eachparticular system.

Other difficult problems are alsoshortly addressed, such as obtaining relevance judgments and choosinga database for performance comparison. In this article we presenta fully automated benchmark for CBIRSs based on MRML, which can beadapted to any image database and almost any kind of relevance judgment.The test evaluates theperformance of positive and negative relevancefeedback, which can be generated automatically from the relevancejudgments.

However, CBIR true performanceis still difficult to quantify. Setting up a CBIR benchmark is aheavy task and can only be done via the collaboration of all partiesinvolved in the research and development of CBIR prototypes and relatedcommercial products. The Benchathlon effort proposes to create sucha context in which CBIR will be evaluated thoroughly and objectively.In this paper, we present the Benchathlon and its objectives in moredetails. The goal of CBIR benchmarking has been divided into variousparallel and inter-related sub-tasks. One essential such task isthe definition of ground truth data. Since no such data exists, theimage collection is to be constructed from scratch. Copyright issuesshould be resolved so as to be able to freely distribute, extendand modify this collection. Further, different sub-collections shouldbe available for different specialized applications. It is also acknowledgedhere that no unique ground truth exists. Techniques to account foruser subjectivity should therefore be developed. Considering theeffort involved, tools for easing the task of data annotation needalso to be designed. Related to this is the definition of objectivequantitative performance measures. These measures should be boththorough and orthogonal. In other words, they should allow for acomplete evaluation and highlight weaknesses and strengths of theCBIR system under evaluation. The goal being both to compare systemsand to help system developers to profile their techniques. To usethis data in practical evaluation, there is also the need for definingstandard test queries and result sets. Domain-specific constraintswill strongly influence the design of such test cases. Another aspectis the feasibility of CBIR benchmarking. This imposes the definitionof a flexible software architecture enabling automated benchmarkingwhile leading to little (optimally no) programming overhead. Again,legal issues about the openness of the systems under evaluation shouldbe accounted for. In our paper, we also shortly present the solutionsproposed by the Viper team at University of Geneva. These realizationsare gathered under the umbrella of our GIFT project where the centralfeature is the Multimedia Retrieval Markup Language (MRML), an XML-basedcommunication protocol that we think is a necessary tool for enablingCBIR benchmarking.

As a result, textual and visualfeatures are treated in the same way, facilitating true multimediaretrieval. The MRML protocol also allows other applications to makeuse of the search engnes.

This insight has spawnedtwo main directions of research: Query By Example (QBE) with relevancefeedback (i.e. learning to improve the result of a previsously formulatedquery) and the research in query formulation techniques, like browsingor query by sketch. Browsing techniques try to help the user in findinghis target image, or an image which is sufficiently close to thedesired result that it can be used in a subsequent QBE query. Fromthe feature space viewpoint, each browsing system tries to permitthe user to move consciously in feature space and eventually reachthe target image. How to provide this functionality to the user ispresently an open question. In fact even obtaining objective performanceevaluation and comparison of these browsing paradigms is difficult.We distinguish here between deterministic browsers, which try tooptimise the possibility for the user to learn how the system behaves,and stochastic browsers based on more sophisticated Monte-Carlo algorithmsthus sacrificing reproducibility to a better performance. Presently,these two browsing paradigms are practically incomparable, exceptby large scale user studies. This makes it infeasible for researchgroups to evaluate incremental improvement of browsing schemes. Moreover,automated benchmarks in the current literature simulate a user bya model derived directly from the distance measures used within thetested systems. Such a circular reference cannot provide a seriousalternative to real user tests. In this paper, we present an automaticbenchmark which uses user-annotated collections for simulating thesemantic gap, thus providing a means for automatic evaluation andcomparison of the different browsing paradigms. We use a very preciseannotation of few words together with a thesaurus to provide sufficientlysmooth behaviour of the annotation-based user model.

A suitably sparse set of colour and texture featuresis proposed. A scheme based on the frequency of occurrence of featuresin both individual images and in the whole collection provides ameans of weighting possibly incommensurate features in a compatiblemanner, and naturally extends to incorporate relevance feedback queries.The use of relevance feedback is shown consistently to improve systemperformance, as measured by precision and recall.}, owner = {steph}, timestamp = {2008.05.04}, url1 = {http://vision.unige.ch/publications/postscript/99/SquireMuellerMuellerRaki_scia99.pdf}, vgclass = {refpap}, vgproject = {viper} } @inproceedings{VG:MSM1999c, author = {Henning M{\"u}ller and David McG.

In particular, responsetimes of under one second are often specified as a usability requirement\cite{Nie97}. This paper compares several methods for improving theevaluation time in a content-based image retrieval system (CBIRS)which uses inverted file technology. The use of the inverted filetechnology facilitates search pruning in a variety of ways, as isshown in this paper. For large databases ($> 2000$ images) and ahigh number of possible features ($> 80000$), efficient and fastaccess is necessary to allow interactive querying and browsing. Parallelaccess to the inverted file can reduce the response time. This parallelaccess is very easy to implement with little communication overhead,and thus scales well. Other search pruning methods, similar to methodsused in information retrieval, can also reduce the response timesignificantly without reducing the performance of the system. Theperformance of the system is evaluated using precision vs. recallgraphs, which are an established evaluation method in informationretrieval.

This provides a rigorousmeans of choosing between competing image database organization systems,and of assessing the performance of such systems with respect tohuman judgments. Human partitionings of an image set are used todefine an similarity value based on the frequency with which imagesare judged to be similar.

We first derive a statistic, $\kappa_B$ for measuringthe agreement between two partitionings of an image set into unlabeledsubsets. This measure can be used both to measure the degree of agreementbetween pairs of human subjects, and also between human and machinepartitionings of an image set. It also allows a direct comparisonof database organizations, as opposed to the indirect measure availablevia precision and recall measurements. This provides a rigorous meansof selecting between competing image database organization systems,and assessing how close the performance of such systems is to thatwhich might be expected from a database organization done by hand.We then use the results of experiments in which human subjects areasked to partition a set of images into unlabeled subsets to definea similarity measure for pairs of images based on the frequency withwhich they were judged to be similar. We show that, when this measureis used to partition an image set using a clustering technique, theresultant clustering agrees better with those produced by human subjectsthan any of the feature space-based techniques investigated. Finally,we investigate the use of machine learning techniques to discovera mapping from a numerical feature space to this perceptual similarityspace. Such a mapping would allow the ground truth knowledge abstractedfrom the human judgments to be generalized to unseen images. We showthat a learning technique based on an extension of a Kohonen networkallows a similarity space to be learnt which results in partitioningsin excellent agreement with those produced by human subjects.}, owner = {steph}, timestamp = {2008.05.04}, vgclass = {refpap}, vgproject = {viper} } @inproceedings{VG:SqP1997, author = {David McG.
